You wrote "Windows XP' and just 2 months ago we had the opportunity to test old XP (notice no service packs?) to see what WiFi support there was. It was very basic and only allowed 802.11b/g networks with no password and some WEP protected networks.
To fix this to work with newer networks we connected with ethernet after turning off the WiFi (very important step it turned out) and let it update to SP3 and the other 200 patches. Even then we were not done. A new WiFi driver had to be hunted down from the laptop maker and installed.
Finally we could connect to all the office networks.
You bring up a good question. Do you think Microsoft should correct this area so folk don't have to be network/Windows experts?
My daughter's laptop can no longer connect to the internet. It is a relatively old laptop and she just uses it when she goes awaay, but now she can't connect to any new wireless networks or even connect directly with a cable. The computer can see the networks. It asks for the password to join secured networks but then it goes no further. No error message or anything. What can the problem be? It used to connect without any problems.She doesn't want to buy a new laptop because she uses it so rarely. It is running Windows XP. Please help. We have tried with three different networks. Other computers and cellphones can connect with the home networks, so the problem can't be with that.
