linux PEAP MSCHAPv2 problems

Archived from groups: (More info?)

I'm trying to connect to a user-authenticated campus Wifi network using
PEAP.
This is the quick connect settings guide from the campus website.

SSID (Network Name) TTUnet
WEP data encryption Enabled
Automatically provided WEP key Enabled
IEEE 802.1x authentication Enabled
EAP type Protected EAP (PEAP)
Protected EAP Authentication Method Secured password (EAP-MSCHAP v2)
EAP MSCHAP v2 Properties - Automatically Login Disabled

I am using a laptop with Mandrake 10.0 and a builtin broadcom wireless g
adaptor(I had to use ndiswrapper to make it work). The system connects to
both WEP and open APs with no problems. The new variables here are PEAP,
autmatically provided WEP key, and the login after association. I have
the username/password that's required.

I tried using Xsupplicant, the only utility I could find on the subject,
but I get inconsistent log errors and many "the network is down" errors.
I know this network is functional since my XP fiends are doing just fine.
I am not confident that I configured Xsupplicant correctly, but I am lost
on finding the error.

Any suggestions?
