Special Wi-Fi authentication I got access to a Wi-Fi network which claims to use PEAP-MSCHAPv2 authentication. My phone (X10 mini pro with Android 1.6) was able to detect it as a WPA-EAP network. It even asked for the password to connect to it (which I have), but as far as I know I have to use an user name with PEAP-MSCHAPv2 too.
The question is: can I somehow connect to that network with my username+password? If not, will it be possible after the 2.1 update for X10?
Yes, connecting to a PEAP-MSCHAPv2 network with 1.6 is not possible due to a lack in the network manager. After an upgrade to 2.1 or 2.2 it is possible.

Alternatively you might want to root the device and enter your login credentials in your wpa_supplicant.conf file manually.
