So everytime my girlfriend tries to connect to our wireless network from her laptop it PRETTY much SHUTS our internet down. It will knock the desktop and printer off and it won't even connect itself. I tried connecting my laptop after this happened and it worked great, connected COMPLETELY and the desktop and printer STAYED online... I'm confused as to why only her laptop does this and would appreciate and advice on how to fix this situation. I also tried shutting the firewall off and this did not help. ThanksWild Wireless Woe. 
What you describe is very unusual. We would like to have a little bit more information. Especially some information about what kind of router you have. And what brand sand model of laptop are you using.
Do you mean to say that your printer is also wireless? And the  desktop also connect through the wireless? Are you able to connect from the router directly to your desktop?
It cheers that the laptop in question is causing interference to the wireless connection. Have you tried moving that laptop further away from your stuff lip to see if interference stops?the router is a linksys but it also has cisco on top of it... The laptop is a Toshiba not even a year old with VISTA on it... The printer is wireless but that doesnt matter, what's bugging me is being in the middle of something and when she turns her laptop on and tries to connect it kicks me off on the desktop. The desktop is not wireless, it's hardlined in from the router directly... Hopefully that helps. Thanks again
