Statut : Not resolved

Hello,


We have a Modem that goes into a router which goes into a like 20 port high speed switch, then there is 1 line that goes to each room. Some rooms are quads so guys have their own routers, but sometimes the internet gets cut off because my computer gets assigned an IP from their router not the internet router. Also they are only plugged into the switch part of their routers in a sense extending the big switch. And finally there is a wireless router which we have set up which doesn't seem to interfer with the rest of the set up. What should I tell the guys, that they need to buy network switches without routers? any ideas?
Configuration: Windows XP
Internet Explorer 6.0

Hello


Like you say, you need to breakup the broadcast domains. If they have a DHCP server running on your ethernet segment w/ no broadcast filtering, than the first DHCP server to reply to a request will be used by the client -- and you get the wrong address/gateway.

So maybe you can:
-Disable the DHCP server in all the routers where it's not suppost to be
-use static addresses instead of using DHCP
-Put all your ports into different vlan's on the switch & the gateway in all vlan's. This'll fix hte broadcast domains, but will break LAN connectivity between the hosts.
