Net connection problem in Vista through wireless network

PLEASE HELP!!!

So I have a Netgear WPN111 wireless adapter connecting to a Netgear WPN824 Router which is connected to the internet. It's been running fine on my Windows XP setup but last night I installed Vista on my machine as well and now can't get the thing to connect to the internet at all! I installed the Vista adapter driver from the Netgear pages and it did connect to the router but wouldn't give me an Internet connection. Windows Vista also finds my wireless network but can only connect to it with a 'limited connection', and still no internet. Can anyone help me out?

Also, as an aside, I tried to uninstall the WPN111 software to reinstall it but for some reason it won't remove itself! I tried the uninstall option in the start menu a few times coupled with a system reboot but it did not remove anything. I similar thing happened when I tired it in the add/remove programs section. It would run but not actually remove anything, not even the entry in the add/remove programs window! weird. Any help?

Thanks.
