I have a wireless network at home, to which I connect using a laptop and a desktop. Everything has been working well for several months, but recently my desktop (WinXP) developed a problem: it drops the network connection, then reconnects, then a few seconds later drops it again, reconnects, etc.
The signal strength shows up as "Excellent". The laptop (Win7) still connects to the network without any trouble. So I would have guessed that the wireless card in the desktop has gone on the fritz... except that my workaround seems to be rebooting the router! Whenever this starts happening, I just reboot the wireless router, and now the desktop connects and stays connected... until the same problem recurs a couple of days later.
Any ideas what might be going wrong here?
