    Hi. We have 3 computers connected to our router via cable and the network works just fine. Recently 2 friends of ours have joined our network with their laptops via wireless and it still worked fine. However, when another friend stopped by and wanted to connect (again via wireless) as soon as she connected to the router the whole network stopped working for everybody. I tried to give her a static IP so there wouldn't be a conflict anywhere but that didn't help. If I connected her through the cable, then everything was fine. But as soon as she tried wireless, the whole network stopped working again. None of the other computers cause this problem, just hers. Whenever she tries to connect, the network always stops working for everybody.
    All the systems are win 7. the router is : cisco RangePlus Wireless Router, WRT110

    Make sure she has the latest and correct wireless driver (from the laptop manufacturer's site if the adapter is integrated).

    Just did. The drivers are up to date. I tried removing the password from the network to see if it helps but no. as soon as the laptop joins the network, the internet connection gets lost on all the computers (and the router cannot be accessed). As soon as I disconnect her laptop, it works fine.

    There have been a few other cases of Vista or Windows 7 crashing a wireless network. No solution that I know of other than try a different router or different wireless adapter. Or, if it's a guest, tell 'em to switch the wireless off and use the ethernet. :(
