Title:
Precise 12.04 cannot connect to wpa2-enterprise network using
PEAP+MSCHAP2
Status in “wpasupplicant” package in Ubuntu:
Confirmed
Bug description:
I upgraded to ubuntu 12.04 a few days ago, and lost the ability to
connect to my works wpa2-enterprise network. I just had the chance to
reboot off of a 11.10 live CD to verify that 11.10 works, and thus
that it is not some problem with the wireless network.
Looking at wireshark, 12.04 sends a Client Hello which the AP reponds
to with "Alert (Level: Fatal, Description: Bad Certificate)" while
11.10 seems to accept the Client Hello message.
I upped wpasupplicant to debug log level on both attempts and am
attaching the part of syslog where I was attempting to connect to the
access point.
The question
https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/183754
looked similar, but their workaround of upgrading the firmware seemed
unlikely after I checked that both 11.10 and 12.04 are using the same firmware
version.
I'm using a thinkpad with an intel wireless card:
