802.1x WiFi connection problems

[Guest Pinko_Commie]

I'm having issues connecting my Desire to the WiFi network at work.

It works perfectly on my Nexus One, yet my Desire never connects. Interestingly, when I run the Desire rom on my Nexus One, then it doesn't connect either.

It's 802.1x PEAP-GTC with no certificates involved.

On my Nexus I choose:

EAP method: PEAP

Phase 2 authentication: GTC

CA Certificate: N/A

Client Certificate: N/A

Identity: username [this is my AD username on its own, no domain prepended]

Anonymouos identity: [left blank]

Wireless password: password [my AD password]

On the Desire there is no drop down for the CA or Client certificates, I never get any error, sometimes (for instance when i comes out of screen blank) it says connecting, but then always just goes back to "Remembered, secured with 802.1x EAP". I can press connect as many times as I like and it never connects.

Any ideas?
