Public bug reported: 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: root@myrada:/root# sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm *-network description: Ethernet interface product: 82579LM Gigabit Network Connection vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 logical name: eth0 version: 04 serial: f0:de:f1:6f:be:a3 size: 1Gbit/s capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=1.5.1-k duplex=full firmware=0.13-3 ip=131.215.54.184 latency=0 link=yes multicast=yes port=twisted pair speed=1Gbit/s resources: irq:17 memory:f2500000-f251ffff memory:f252b000-f252bfff ioport:5080(size=32) *-network description: Wireless interface product: Centrino Advanced-N 6205 vendor: Intel Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 34 serial: a0:88:b4:6a:44:3c width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.2.0-21-generic firmware=17.168.5.3 build 42301 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn resources: irq:20 memory:f2400000-f2401fff No LSB modules are available.
