If these laptops are both relatively new they should come with the wireless networking feature already installed. Once your network is set up on your base computer, I am assuming from your statement you have this hooked up already, on each of the laptops you will need to configure each of them to connect to your network (ie....your router). When you set up your router you had to apply your network name, password, you would have chosen to protect probably using the WEP, WPA feature (WPA stronger). You use those same items to set up each laptop..... Go to START, then on the right choose NETWORK, look towards the top of the box and you will see NETWORK AND SHARING CENTER. Another box will open and on the left side choose SET UP A CONNECTION OR NETWORK. Then choose "Manually connect to a wireless network", hit NEXT. You will then enter the same information that you used setting up your router..... NETWORK NAME (example: Dawn's Network), then the security type (WEP or WPA as I said earlier), then insert your passphrase, then put a check next to " start this connection automatically", then click on NEXT. The next page you will choose "CONNECT TO....." and then hit close at the bottom. You will now be connected to your network (router). You follow the same steps for each computer you wish to add to your network. I hope this helps.... Good Luck!
