Wifi
Maddening problem. My wireless router packed it in and I bought a new one from Linksys. It would not allow three of my family's computers (I work from home and have three, they have three also) to log on to the network. I took that back and bought a Belkin, which allows those computers that work to operate faster, but the same three (that worked fine before and the laptops continue to work when out of the house) either will not log onto the network, or when logged on will not allow the browser to receive a signal. No packets are returned. All computers use Windows XP, they all have different wireless adapters, some built in and some plug in. The range is around 25 metres but even if the laptop is in the same room as the router it does not help.
I have tried all variations in security, to no avail. One of the laptops belongs to my wife and of course it is all my fault that she can no longer get onto the internet. I have wasted days on this, and if anyone has a suggestion please let me have it...
