N900 School WIFI problem
 

I am trying to connect my N900 to Texas A&M Wifi, but I couldnt make it work. I had tried some many things but still didnt work
here are my settings:
1. infrastructure, WPA with EAP
2.EAP type: PEAP
3.SELECT certificate: NONE, EAP method: EAP MSCHAPv2
4. my school doesnt not require domain name sl
Username: username i had tried with both with and without domain
Password: xxxxxxxxx
5. advanced, on EAP manual user name checked and manual username i had tried both with and without domain name.

after all, none of the above works. My school network requires the things that i just put. WPA-PEAP-MSCHAPv2, i am assuming the problem is certificate, i couldnt able to find any certificate to it, but i found the certificate on certificate managerment: it is godaddy

please help. thanks
