I have a Dell Latitude D800 with Windows XP OS. I have never had a problem connecting to wireless/direct ethernet networks. I just moved from my home in PA to CO and moved into a sublet with 3 other people. These people are able to connect (wireless) just fine to the network they set up awhile ago. I have not been able to connect to the network here since I moved in 2 weeks ago.
When I try to connect, the dialog box says that its trying to connect for about a minute or two and then just goes away, with out an explanation of not connecting. The other people that are able to connect to the network have the network properties on their computers set as "Network Authentication: WPA2-PSK" and "Data Encryption: AES". I have set the properties the same on my computer. There is a network key that I know is correct. The roomates here have had others come and use there network just fine by typing in the network key. I can actually connect to networks at Best Buy, and two coffee lounges. But I can not connect here and also can't at another house.
Best Buy told me to make my settings "Automatic" and then do a power cycle with the modem and the router, then if that didnt work (which it didn't) to try to connect to the ethernet cable from the modem directly...which does not work either. I went back to Best Buy and they "reset the Windsock" on my computer, thinking it would connect then. It still does not- I even did another power cycle afterward and it did not. Best Buy's Geek Squad doesn't know what is going on. They are now recommending that I check forums first, and then reinstall Windows XP to fix it.
