I used to be able to connect to our campus WPA Enterprise WiFi with my older N810, until they upgraded the server from Windows 2003 (IAS) to Windows 2008R2 (NPS). I also now have an N900 and it is also unable to connect.
There is a long list of devices which connect just fine to our campus network, some of which I've set up for professors myself and others are confirmed to work in other colleges and divisions:
Blackberrys, HTC smartphones, Apple iPhone/iPod/iPad, Motorola Droid, the Archos 5 Internet Tablet, and more.

I've been using the settings talked about in post #10, since they are the same as we use on campus, with the key step being to set the domain\username under the Advanced/EAP tab, which I understand is the step that people tend to not know about until they research it.

I just can't see how it can be anything I'm doing wrong at this point. I've tried putting in the information over and over and over and over, on and off for the past three weeks (somehow thinking it would magically work the next time, putting in the same information)

And yet, I just recently set up an iPod Touch and it was connected in less than a minute. My Windows XP and Windows 7 laptops connect just fine as well.

If there is no bug in the Nokia code, then I'm really at a loss here.

Actually, I don't want to get someone mad at me for muddying the waters, but I also find it interesting that a professor with a Nokia N82 is also unable to connect. Other than the Nokia N900, N810 and N82, the only other WiFi -capable device known not to be able to connect to our network is the Zune HD.
