|I recently bought a Packard Bell netbook with a built in atheros AR5007EG wireless adapter, and also got a Wisacom USB 200, which uses a Realtek RTL8187 chipset.|
When I got the computer the Atheros would connect to the wireless network without problems, but the USB wouldn't. It'd either sit for a minute on 'waiting for network' or 'aquiring network address', then result in 'limited or no connectivity' with some non 192. ip address.
Then I installed Xubuntu and reinstalled XP, and now I have the same problem with the Atheros.
Both adapters are working fine because I warwalked some unsecured networks in the city and they connected to about half of them. The other half got the above errors in Xp, in Xubuntu it's just 'connection failed'.
I've been using some other network utilities and both cards are working fine for those.
Thinking it seems like a DHCP issue, I tried manually setting my IPs, which resulted in very quick connections but no gateway and no connectivity at all.
I've tried uninstalling/reinstalling and updating the drivers etc.
This is really weird. I have no idea what the problem is.
