your neighbour's router might be configured to issue out only one IP address so even if you have the key, if neighbours pc is on then you will not be able to obtain an IP address and therefore browse

I have the same issue but possibly with an even stranger twist. I have a wireless HP desktop which finds the network and gets into the internet fine. My laptop finds the network ("signal- very strong") but when I go to my browser, cannot get into the internet. All pages fail.

Then I take the same laptop to my office, and I am able to access the net there through that wirelss network with no problem at all.

So its not the router, or the HP desktop would not work. It can't be the laptop, or my net connection at work would not work. I am afraid to change any settings on the laptop, for fear that the it won't work at the office either. Please advise if possible.

Hi Jo-Gee, any chance you could drop me an email? I'm having the exact same problem as you and am wondering if you've figured it out yet?

my work laptop works fine at the office, but wont pick up the net at home despite two other laptops picking it up fine, its driving me insane!

would really appreciate it!

djbalts › k123 - Dec 18, 2008 1:05pm GMT

Did you ever find out how to fix the problem you were having with connecting to the internet? I am having the same problem>

k1234 › djbalts - Dec 18, 2008 1:11pm GMT

no I didn't! honestly i'm going mad here, even all the IT whizz-kidds don't know what the problem is and I can;t imagine why when there seems to be quite a few of us with the same problem! I honestly don't know what else to do. :-(

Karred › k1234 - Feb 14, 2009 1:17am GMT

sounds like a corrupted wireless profile, delete it and resetup the connection and it should work fine

charles › k1234 - May 16, 2009 7:33pm BST

find someone connected to network

start ,run , cmd then type, ipconfig ,on thier computer

go to network connections on your computer
choose the connetion your trying to make
right click, choose properties

choose tcp/ip for XP or 1pv4 for vista

choosee properties

choose, use this ip address

type in same info, but change last number

example

If 192.168.0.142

you type

192.168. 0. 143

or 144 or 154 or 152

this will work

Sho › k123 - Dec 22, 2008 6:43pm GMT

K1234,
Did you get a solution? I have the same problem. Not able to connect to internet from home network, but works fine at work.

k123 › Sho - Dec 30, 2008 2:43pm GMT

Hi All

well i finally figured out the problem, turned out there was nothing wrong with the modem, or the router, or the IP address, i just had the password wrong!

my landlord didnt realise that his password had been changed a while back and thats what was causing the problem, even though the failed connection kept saying it was the IP address thing.

someone has put a post on here about changing the last digit of the IP address, so I asked my landlord to look up his IP address with his provider and thats how we realised the problem.

maybe some of you guys have the wrong password too?

kc › k123 - Jun 15, 2009 3:09pm BST

apparently, i got the wrong password...thanks

liz › k123 - Sep 21, 2009 11:04pm BST

which password are you talking about? I have the same problem with not connecting but i cannot seem to figure it out.

e › k123 - Jan 13, 2010 8:19am GMT

thax man. i was entering wrong network key

Sho › JoGee - Dec 22, 2008 6:14pm GMT

I have the same problem as you described since last friday. Browser do not work from home, even though there is strong connection. Am able to VPN and connect to internet. The same borwsers, ie & FF works fine from work network.
Did you have any soultion for your problem?

Sho › JoGee - Dec 22, 2008 6:25pm GMT

Goe,
Did you get any solution to the problem? I have same exact problem. Tried all cmd promt - ping, tracrt etc - nothing worked. Its not working from home, but is ok at work network.
Please let me if you get any solution.

Sho › Sho - Jan 27, 2009 2:20pm GMT

All,
I fixed my problem. Restored the system to a date prior to when the problem started. Now I am able to use both ie & Firefox browsers.

Silky › JoGee - Apr 7, 2009 8:26pm BST

Hi, just wanted to know if you ever fixed that problem, my lapop is connectedthru wireless thru my local intenet provider and i can not get into anything involving the internet. It says i havea strong connection but get nothing. HELP!!

Vijay › Silky - Apr 11, 2009 5:53pm BST

Dear Silk...

Try this..

First connect your nertwork by 'connecting network'
then go to your CMD window
Type following in 3 steps, after every step use ENTER bUtton.
1. type IPCONFIG/ALL (then ENTER)
2. type IPCONFIG/FLUSHDNS (then ENTER)
3. type EXIT (then ENTER)
Please let me know if this work, then u can create a batch file rather than typing every time.
Thanks..
Vijay Pillai,ND

Hi! I need your help!
Windows 7 - I connect via my modem, but it says I am not connected to any network in the network and sharing center. Internet is working, but I am not able to share my internet connection via ad-hoc connection (because of windows not being able to recognise it is connected via modem) I solved this once by restoring PC to a prior state, but I cannot do that again!
Also, my wi-fi connection does not work - it seems like it is just ignoring the conncection, it shows NOTHING even though other devices connect without a problem. My wi-fi is functional, I can connect to other networks, but not to mine!

ForgottenHero - Jun 25, 2009 6:36am BST

Hey,
recently our internet stopped working so we bought a new modem, this didn't help so we called our ISP and they fixed it. Then our new modem stopped working so we reverted back to the old one. NOW we can only have one connection to the internet at a time using our old wired router. we plug in 2 with LAN cables and only the first one will work! and even when that one DOES work the internet is extremely slow! Please offer a solution as this is REALLY annoying!

rahman - Dec 18, 2009 11:03am GMT

ntt Jul 30, 2008 1:07am BST

Check and see if you have an IP Address confliction within the network. In other words 2 computers with the same IP addresses. If you do, just change the last number of the string.

Here's how:

Go to Settings (where the Start is at bottom left) and select Network Connections.
Find Wireless Network Connection. Right mouse click on it and go to Properties.
Highlight on the Internet Protocol (TCP/IP) and click on Properties.
At IP address: , change the last digit of the IP address. Chose a higher number. Chances are the lower numbers are all taken. Click Ok and exit out of all the settings.

Now try to open your internet browser again.

Hope that helps.

Hi ntt,

Thanks a million for your life-saver post on how to change the IP address to a higher number. Before that, I just couldn't figure out why FireFox keeps telling me that it can't connect to the server when I was obviously connected to the internet, as indicated by the Wireless Network Connection icon in the system tray.

I discovered that under Internet Protocol Properties, the Use the following IP address option was selected. I don't even remember ever configuring that :p. Anyway, I've changed the selection to Obtain an IP address automatically. Now everything is a-o-kay and I am back surfing the internet (^__^)

For anyone who's experiencing the same problem, of being connected but unable to load any webpage on the browser, should really give this solution a try.

Thanks ntt, your post saved my day!

hi, i have the d-link router WBR-1310 and i have it connected and everything is on, when i turn on the computer my desktop comp, i have a connection for about 10 min, or if i have a connection and log off for a while i come back and i dont have the connection, i dont know i have tried reseting the modem, i just dont know what the problem might be, could it be the firewall, or the d-link router connfiguration?

Greetings:

I have the same problem. All using Netgear, I have one computer that can get on the internet and two laptops that can't. But my lP is already set to "obtain IP address automatically." Any suggestions for me? Thanks for sharing your expertise.

mitchelli - Jan 5, 2009 3:41am GMT

Bless you for that answer...I had the same problem with a laptop that worked fine, but a desktop that would not work on IE or Firefox. When I checked the IP address where you said on the laptop the internet protocol had no IP addresses but the 'obtain DNS server address automatically' checked. I went into the desktop and checked the same button and damn if it does not work perfectly now. Thanks so much for getting me to the right place.

Dawn › mitchelli - Dec 13, 2009 12:35pm GMT

I cannot get any website to display in IE, despite having an excellent internet connection, and want to try the suggestions on this website. How do I find the check box for 'obtain DNS server automatically'?

cinqly - Apr 21, 2009 8:06pm BST

My computer is set to automatically acquire the IP address. Explorer or firefox still will not connect to the internet. What do you suggest?

VIVEK › cinqly - Jul 15, 2009 9:11am BST

i also have the same problem few days ago. I searched the solution for around 10 days, but all in vain. and after some days this probelem was automatically gone, so don't worry , u should wait for some days and u will get ur result.

miche - May 7, 2009 6:43am BST

I had the same problem as the person above, but my DNS was not on 'automatic' and that was my problem!

You saved me a sleepless night

This has been driving me crazy for a week, and no IT folks could help! I didn't think it would apply to me aa I'm a Mac user, but I just went to Network Preferences, and changed the IP address, and VOILA! Genius!! Thank you thank you!

barn - Dec 20, 2009 10:07pm GMT

Your suggestion and directions were excellent. There was an IP address in the setup and changing to automatically get an IP address was on the money. Thanks,

TJ Sep 8, 2008 8:33pm BST

To answer your question, have your neighbor do the following,
(Don't type the quotes just the command inside)
Click on start, then run
Type 'cmd'
hit enter

type ipconfig/all
hit enter

You need to have a different IP address than he has, so if his is 192.168.1.11, pick the last number and add 100 to it to be safe, so yours would be 192.168.1.111 (just an example)

Your netmask will be the same as his, 255.255.255.0
your gateway will be the same as his

You also need to have the DNS servers that are listed, there should be 2 of them, write both of them down.

So, on your sheet of paper, you will have a unique IP address, the same netmask and gateway, and 2 dns servers.

Go to your PC, start, control panel, network connections, right click on Wireless Network Connection, then select properties, On the general tab screen, Select Internet Protocol (TCP/IP), and click properties,

Then enter your unique IP address, netmask, gateway, and both dns servers. Click ok, then ok again.

Then on your notebook/pc, click on start, run, type cmd, hit enter
type 'ipconfig/all'
hit enter, your info should match your neighbors except for the IP address
type 'ipconfig/flushdns'
hit enter
type 'exit'

now try to get online with internet explorer, you should be successful, if your not, post back on here with your results and I'll get back to you.

Randy › fullypacked - Jan 4, 2009 3:30am GMT

You know what it is? It's Skype. I had the EXACT same issue. (Cannot load browser windows, when clearly online) I used "System Restore", and chose a point before I had installed Skype, and I didn't have any issues. Originally, I had thought it was a Windows Update or something that did it.

I then downloaded Skype a few days later, and BAM. Problem returned. I did "System Restore" one more time, and haven't had any troubles since. I don't know how to fix the problem, but at least you now know what is causing it.

Rob - Jan 5, 2009 8:17pm GMT

Thanks TJ, followed your instructions to the letter and the wireless is now working on both work and home laptops.

Alexander - Jan 11, 2009 12:09am GMT

Hello TJ,

Sorry for the trouble, but you are the only person that seem to know about the confusion over the dsl->wifi router->pc problems out of the whole bunch of forums I have gone through during the past 3 days.

I carefully looked at the suggestions you were posted, but could not exactly match them to my situation that I am hoping you would be able to help me resolve.

So, my problem is, when I am connecting my laptop tp the ADSL modem (speedtouch smth, I believe), I have no prob accessing the internet. Although, when I try using the internet through the Lynksys WRT300N V1.1 router, I cannot open any web page neither in IE, nor in FF. My skype is connected though, no problem calling, talking, messaging...

This problem drives me nuts, as I disabled all the security features in the router, except for mac filtering, tried mac cloning and whole bunch of other suggestions I found on the WWW.

I saw somebody else having similar problems in the forum, but did not see your response with a solution to this particular problem and figured you might have sent it via e-mail.

I will greatly appreciate your help on this TJ, and will be looking forward to your reply.

Alexander

VIJ - Mar 15, 2009 5:19pm GMT

TJ,
This is my first post oremail in this site. I am happy to tell you that my wifi internet connectivity problem is solved by following your instructions. i had probem for last 6 months on my new Aspire 5920G vista!!!
I went thru many site, technical experts on respective make of my PC, MODEM and serive provider.
Today it get connected and thank you so much and respect ur knowledge on networking.
Since I get just connected now, i have to watch for sometimes and probably come back to you for a 100% clear connectivity.Even though internet get connected, I could see 2 problem. Every time I have to manually type IP address on IP/TCP-4 setting, Automatic detecting is not working. At command prompt, when I type ipconfig/flushdns, it shows 'The required operation requires elevation' (even though internet get connected).

Let me ork couple of days and check how it works.
Thanks in advance
regards
Vij..

SeaGirl - May 25, 2009 4:54am BST

Hi TJ

I am not piggy backing service off anyone, but have same issue as the others. Can connect hard line, but not wireless.

I did everything you suggested - no luck.

I have Comcast service - Netgear - Averatec computer

Changed the IP address and when I perfomed the ping command, the address did change, but still no go.

I have been fighting with this issue for 7 months off and on (b4 I go crazy), so any other suggestions? The obvious thing I think I am missing is the DNS servers.Where do they come from?

Thanks!!

Hi, when you fail to connect to the internet, go internet options and delete all temps, cookies etc. Restart ie7, it will not connect right? but now go back to the cookies and copy paste what it shows.

I'll will be very interested in the answer to Jules as I have a similar problem. At home, I have the router connected to my PC and my daughter has a laptop with wireless. All this worked fine before she left for the summer. Now that she is back, her laptop sees the internet wireless connection but does not connect to the Internet. Now two weeks later, I moved my PC to another room and the same thing is happening to it. Connection is there but can't access the Web. I know that the adapter is working properly as I use it on my work laptop and everything is fine. Got any ideas for me too?

Thanks

tjmartineau - Sep 20, 2008 6:55pm BST

Gab,

If the adapter works on a different device, then we know the router, modem, and adapter are working correctly. That leaves both your PC and other laptop.
Let's start with your PC,
click on start,
then control panel,
then network connections,
then right click on Local area connection (Or wireless depending), and select properties.
On the first window, select TCP/IP, then click the properties button,
Obtain an IP address automatically and DNS automatically should be selected. (if not, do so for now)

If that's ok, close the windows, click on start, then run, then type cmd and hit enter

Type ipconfig/all and copy and paste what you get on here.

A problem where the devices can see the network, but not the internet, usually has to do with the DNS Servers, so after you do your ipconfig/all, type the following,

ipconfig/release (then hit enter)
ipconfig/flushdns (then hit enter)
ipconfig/renew (then hit enter, and wait, it may take a minute)
ping news.google.com (then hit enter, if this replies, then you have internet access, if not, last step)
ping 74.125.19.104 (then hit enter, if this replies, you have internet, but not DNS, so you cannot type names to get to websites, and the fix is a tad more complex.

Let me know the results.....

TJ

TwoTone12 › tjmartineau - Oct 1, 2008 6:28am BST

Hi.

I'm having similar problems and was wondering if you can help. You were helping someone and told her to ping news.google.com. I tried that and I could not find the "host". Then I pinged 74.125.19.104 and got a response. You stated the fix is a bit complex.

Can you tell me about this fix. Thanks!

Anna › tjmartineau - Oct 11, 2008 1:02pm BST

Hi TJ,

"ping 74.125.19.104 (then hit enter, if this replies, you have internet, but not DNS, so you cannot type names to get to websites, and the fix is a tad more complex.

Yes, this is what is happening to me as well. I tried everything but it seems it is not working. I have used the laptop on a different network and it works just fine.

How can I fix this problem?

Many thanks,

Anna

Jeanette › tjmartineau - Oct 15, 2008 6:48am BST

I cannot ping names of websites only numbers. The ping states packets are sent and dropped. Please can you type the solution for me, as you state it is a little more complicated to sort out the DNS. I phoned my cable company and they said I need to update my TCP/IP settings but couldn't help me! The LAN settings state computer is connected, I can use my laptop off the wireless, but cannot type web addresses to get internet. Get message stating this page is unavailable. Please can you help?

went through previously listed fixes and with ping of both webpage and ip address, i get sent 4 packets but 0 received 100% loss for both

what's next?
thanks a million in advance

Puds38 › tjmartineau - Dec 26, 2008 3:13pm GMT

I think I'm having a similar problem. I was on the phone with Comcast tech support yesterday and tried the config/release and config/renew trucks but no go. The modem appears to eb working, the router appears to be working. I have an IP for the router and nothing for the internet and I keep getting the low/no connectivity message.

Dawn › tjmartineau - Dec 13, 2009 2:23pm GMT

Hi, TJ.

We have three wireless computers (one desktop, plus two notebooks), two of which are connected to the internet with no problems. My notebook works for Skype, but not Internet Explorer --it "cannot display" any website (name or IP address). The modem connection is excellent.

I tried netsh winsock reset catalog and netsh int ip reset reset.log . I tried ipconfig/release >> flushdns >> renew. I am able to ping both news.google.com and 74.125.19.104. Nothing is checked in TOOLS > INTERNET OPTIONS > CONNECTIONS > LAN SETTINGS. My notebook is set to automatically obtain IP and DNS. I have checked the IP addresses of all three computers and they are all different.

Can you suggest anything else to try?

Bless you for your knowledge and clear instructions!

Thanks in advance.

Dawn

thank you very much, TJ, for getting back to me. Still not working. I thought it would be best for me to copy here the response I got for both the laptop and PC. Hope it helps to figure out what is wrong.

Your help is greatly appreciated. Thanks again and I will look forward to see if you have something else I can try. Have a great day.

To get to the config page...

Take your laptop and connect directly to your router.

Click start
then run
type 'cmd' then hit enter

type ipconfig
hit enter

the gateway ip address should be the modem's ip address. (Like 192.168.1.1 or something...)

Open up internet explorer, in the address bar, type that address, hit enter

Login - username is admin password should just be blank

The home networking thing....that's what we're going to accomplish here...

Hey so I have the same problem as above, and I was messing around on the config page. I reset the router/modem, and now I can't even access the config page. Any suggestions? Do I need a new router/modem and will it work with the ISP? Send me an email if you have something, I'd love anyone's anwers to this. After I do connect to the config page, what settings do I need to put in? I messed it up and lost internet, though the DSL light works, ports work, cable works. I know enough to screw it up, not enough to put it back together again. Thanks,
Hal

htyler › htyler - Oct 1, 2008 10:47pm BST

Well, not exactly the same problem. I can connect (sort of) to the network, it gives me an IP address but no DNS clients when I check it through msconfig. I assume that means the DNS isnt working, how do I fix that? I can't even connect to it....

I had the same problem. My internet stopped working after re-installing Norton (NIS). Solution is to install the wireless driver after installing(or re-installing) the anti virus program.

Forgot to mentioned that at the Internet Protocol (TCP/IP) Properties, the Default Gateway must be the same of the router that it is used. If you're not sure, ask your neighbor to look it up in his/her computer and see what is that number and set it to the same number.

Website that utilize "sitemeater" (www.sitemeter.com) that has tracking code that counts visitors to our site was causing visits from Internet Explorer to crash. SiteMeter is bringing down every site where its counter code is loaded when the visiting browser is Internet Explorer - The text of the error is â��Internet Explorer cannot open the internet site.â��

Tens of thousands of publishers use sitemeter to track their content, including thousands of bloggers. Internet. If you plublish your own site or blog, with site meter, you can regain control by removing sitemeter's code from your HTML - for now. If you're visiting sites you'll just need to wait for them to figure it out.

Andi,

A bunch of quick questions to help us narrow down the problem,

What type of wireless router are you using?

Does it work when your laptop is plugged in with a network cable?

Also, does it work when you "automatically configure" the IP Addresses and DNS Servers...(I assume not, because if it did, you wouldn't have posted here, but just to be safe).

When did this last work for you?

Have any updates been installed recently? If so list them.

Are you 100% certain that your Wireless adapter is installed correctly? (You do see it as an available option in network connections and such?)

Are you able to connect to others networks? (Meaning does this just happen at home, and not at work/the library...)

Sorry for the questions, it will help tremendously though.....

TJ

Andi › TJ - Sep 11, 2008 2:29pm BST

Its working now.
It was the new windows update thing.
I did system restore and it was fixed. :P

Thanks for the help.

Jules › TJ - Sep 19, 2008 2:39pm BST

Hi TJ,

I have a similar issue - we have 1 desktop and 1 laptop computer, the desktop is wired directly into the modem and the laptop connects wirelessly. The laptop connection is working fine, but the desktop is saying the modem is connected but is not allowing internet pages to be viewed and programs with internet connections to work. I have had 2 updates on my computer this week, and when I tried to restore (as Andi had done) it tells me that my computer has not had any updates, so I am a bit stuck.

Any advice you have would be greatly appreciated.

Many thanks,

Jules

TJ › Jules - Sep 20, 2008 6:43pm BST

Jules,

How do you have both your PC and Laptop connected to the modem? You do have a router connected...right? Or is your modem doing both for you. (If you can grab what make/model your modem is that will help). Are you using windows XP, if so, and this did work before the two updates that you had. Launch system restore, (Click, start, then help and support), Pick a date from last week, or even the week before, just a date that is bold, and when clicked on, states "System Checkpoint" on the side. If that still does not work, I've got other ideas, but let's start there.

Jen › TJ - Dec 18, 2008 5:45pm GMT

TJ,

I have a similar problem to the ones described in this thread. Here is the timeline and symptoms:

I use a cable modem and a Belkin wireless router to connect one desktop and three laptops (at various times) to the internet.

Mon night - All is well; main computer (ethernet-connected Dell Desktop) and Toshiba laptop (wirelessly-connected) both access internet.

Tuesday - Desktop is fine; Laptop will connect to wireless network, but not to the internet.

Wednesday - tried cycling power on modem & router; called cable company, Belkin, and Toshiba; walked through many troubleshooting scenarios; unplugged and replugged modem & router at least 5 times; powered computer off and on many times; hard reset of Belkin router; after 3 hours, determined that laptop would connect to internet with ethernet; after troubleshooting with Toshiba in SAFE MODE and restarting, laptop connected to internet!! Wonderful. However, email would receive but not send. Will work on that in the morning....

Thursday - Laptop will not connect to internet again! Ugh!

Judging from the questions above, this must be a common problem. Do you have a procedure to fix this connection problem?

Thanks,
Jen

Jen › Jen - Apr 21, 2009 4:30pm BST

Well, a few days after I wrote the post above, I was finally able to get my internet connection working again. I tried everything, it seems, and as best I remember it, changing the IP address of each laptop is what fixed the system. Makes no sense, really, as I didn't DO ANYTHING to bring this problem on myself. I spent HOURS on the phone with Belkin, Toshiba, Cox, etc. What a waste of time. These systems need more redundancy and reliability.

K9,

Your laptop cannot connect with a wired connection correct? If it's not getting a link light, (your orange one), you may have a bad cable, or a bad wired nic. can you connect your laptop to another's modem/router wirelessly? (At school, the library, work?) Did you recently have a power failure at your house? I've seen many a laptop lose a wired Network interface because of a surge....

Let me know....

Gab, you didn't lose me, I got caught up with way too much other things...my apologies.

On your desktop PC, you either have one of three things, a bad cable, a bad network card (Built in most likely), or my suspicion is a bad port on your router.

On your laptop, if it cannot receive an ip, which we all realize via the router's DHCP server, it should, I'm also suspecting your router.

Do you happen to have a spare around? Wired or wireless, it doesn't matter right now, we just need to see for sure that you can hook up a different router, and get an IP from both your desktop, and laptop. You may be able to search Craigslist and get one really cheap, else try a big box retailer to get one cheap and quick for probably around $25 or so, you don't need anything fancy like "Wireless N" or any of that, you just need a basic wireless router.

With that being said, what type of router do you have, you could try factory resetting the router, plug the PC into a different port, with a different cable, and see if it works. Get me the make/model and I'll talk you through it.

dasa - Nov 15, 2008 10:42pm GMT

Hi TJ,
I have a strange problem. We have a router and 2 computers. One runs on vista and other on XP.
The one with vista, wont open websites in IE or Firefox(thought skype gets connected and i have done voice chatting which mean there is an internet connection). i tried to do repair /diagnose and it says windows cannot repair this connection, contact admin, might be problem with your Domain Name Server DNS configuration.
The other computer with XP just works fine with no issues. I tried changing cables and everything , but my vista computer doesn't seem to work. I did ipconfig and the router did assign a IP to the one with vista , but when i ping any website it cant connect.
i am wondering why just only skype works and why shoud it when there is no internet connection?
please help me out. i tried a lot of things but no success so far.
dasa

Dadafz › dasa - Dec 28, 2008 2:28am GMT

Hey Dasa and anyone else with this problem (IE/FF not working, but Skype working). I just fixed this on my friend's computer, at least temporarily.

After checking IPCONFIG and PING, everything seemed fine.

What it turned out to be, was that PROXIES had been setup for both browsers to point to a fake server.

I think Ad Aware removed the nasties, but the browsers were still wacked.

In IE, go to TOOLS > INTERNET OPTIONS > CONNECTIONS > LAN SETTINGS. Make sure that NOTHING is checked. if it is, uncheck it. Click OK, restart IE. You should be fine now.

In FF, go to TOOLS > ADVANCED > NETWORK > CONNECTION > SETTINGS. Make sure that you have DIRECT CONNECTION TO INTERNET selected. If anything else is in there, check off the first option as I suggested and erase anything else.

Hope this helps someone!

shiane › Dadafz - May 30, 2009 4:05pm BST

Thank you so much, dadafz. After trying every solution in this thread (ipconfig commands, verifying that ip/dns were set to automatic, running winsock fix, system restore, DNS manual/automatic setting, etc.) your solution, which took all of 3 seconds as it only involved unchecking two boxes , had me browsing in IE7 in no time.

Thank you TJ. Sorry, I did not mean to be impatient and no need to apologise. Of course, I understand that you have other things that need looking into.

My work laptop, thanks to which I am still connected to the Internet, uses my D-Link wireless adapter and my router (a D-Link too) so I know all that is working fine, which is why I am sort of baffled by all this.

tjmartineau 25Posts September 19, 2008Registration date Sep 23, 2008 3:25am BST

You need to get onto the D-link router's configuration page....see if by chance there is a limitation with the number of DHCP clients that are able to connect. I sometimes only set that number to 1 or 2 depending on the client's connections so that way any other connections are rejected. Set it to a range of 10 or so if it's not.

Also while you are in there, there should be a status page, or a page that states something like, DHCP Client's list. Click on that, and see if there are any connections other than your work laptop. If all is like you state, there should only be one DHCP connection, your laptop. If there are any other connections, your security may have been breached if you have it enabled, if you don't, you'll need to enable some sort of security because your neighbors may be pulling off your network.

Look onto the back of your PC for a second, where your ethernet cable plugs in, do you have a green link light back there (a tiny green square should be lit right above the cables connector). If that is not lit, the adapter or the cable, or the port on your dlink is bad. First, try a different port on the dlink, if it lights up...good...if not...it's the cable or nic.

Let me know if you see anything odd in the dhcp client listing....I sure hope so....if not, and you do have a link light on your pc, we're going to have to factory reset the router and reconfigure it to see if that helps you. I'm heading to bed so I may not reply until morning...(I'm in Omaha, Nebraska, Central Time)

Good Luck and keep me posted...

Thank you TJ. Where can I see the router's config page? Is it possible from my work laptop or should I reconnect my PC directly to the router as it was before I moved it? I looked for it on this laptop but to no avail, maybe because I am connected with an adapter. Would it work if I try to connect my daughter's laptop directly to the router? I'll fill you in on the results later this evening.

Have a great day,

Hope you had a great day. Well I did connect my daughter's laptop directly to the router and everything is working fine. Now my problem is locating the config page of the router. Still searching around for that but not sure what I am looking for. Also should I be setting up a home network? Would that help? Just wondering.

Take care and I'll look forward to hearing back from you.

weeAlec - Oct 20, 2008 3:35pm BST

hanibal -

I've had the same problem which started strangely at about the same time you reported yours...~4 weeks ago.
I don't have a full fix yet, but have traced part of the problem to an infection by a DNSChanger trojan which Norton didn't pick up. All the connections that were assigned were of the "169.xxx.xxx.xxx" variety.
I have a Dell Dimension 3000 using Windows XP as the os.

Running CounterSpy did ID one of the culprits, as well as a few other malware programs on my desktop PC. Unfortunately, I had to call my ISP to make sure the modem and DSL service were both intact & functioning. As of this moment, I can get to the internet ONLY BY TYPING IN THE IP ADDRESS of the site I want to visit...and even then I cannot use any of the links on the target page which require a DNS. If the links are IP addresses then it apparently works fine...but who does that on their websites these days?!

Get a free trial of CounterSpy, or other anti-malware, run it & quarrantine the indicated programs after creating a system setpoint. You may have to call your ISP & get the DNS addresses, etc, and force your machine to use them until you can isolate the keys in your registry which have been corrupted. The place to do that is in the connections tab of the IE you're using.

I have a new ethernet card from NetGear which is performing fine (the computer's built-in adapter I have deactivated for now), and had swapped out the modem for one I knew was working OK. Both are working fine, and my connection to the DSL is not in question. All the drivers for my original Intel Pro VE card were reinstalled from the maker's website, though they proved NOT to be the problem.
There is a trojan in my machine somewhere, but I'm still trying to pin it down & kill it. I'll be running through the registry with REGEDIT later today to see if I can find the "169.*" addresses in there.

And w/o internet ability, it is even harder to update anti-spy/malware definitions, and I have to ferry those items by mem stick to the infected desktop from where I am now (work). Whatever the thing is that's infecting my machine, I think it's a newer variant of the DNS trojan....

If/when I get the final fix or ID of the offender, I'll post more details.

TJ Martineau - Nov 16, 2008 3:14am GMT

Hannibal,

If another computer works fine, you've tried another NIC, and reformatted/reinstalled. The problem could very well be you network cable. You didn't mention that you've changed that.

Wee Alec's post might work for him, but you're not going to have that problem because you know your internet works just fine with another PC. You also have reformatted your hard drive, which is a simple way of erasing a trojan that is on your hard disk.

I've been on vacation with no internet for a while, so my apologies for not getting back to anyone. (It was a great month though!)

To see your present DNS, open connection status>Support>Details

Hope it works for others as well
