finally, i'm able to connect to my uni's wlan network, this is how..
there are 2 networks in my uni, UConnect & UConnect-Setup, i connected to UConnect-Setup, login by entering username and password and obtain and register an MAC address first. i had to do this with Ubuntu as well but i didn't need to do this last year..

I Could connect it with the PR 1.1 but now i can´t.
Can you help me please? I follow all the instructions!
Sorry for my English!

I found N900 *much* *much* easier to setup for WPA-EAP-PEAP-MSCHAPv2 than Symbian (in fact, in supporting two WiFi networks like this, the only phone that was easier to set up was iPhone, as if it can't validate the cert it asks you to accept it). Symbian has most common EAP and PEAP modules disabled, and gives a very cryptic error message when you don't have the CA certificate installed on the phone.

Maybe the Symbian "features" (EAP-PEAP, EAP-TTLS etc. disabled by default, MSCHAPv2 disabled by default etc.) were ported to N9 :-/
