I don't believe this is certificate-related this time. In the linked bug Zacharias Steinmetz says: "Same on my PC running Vivid (3.19.0-22, BCM4313), both with certificate added and ignored."
In my case, it is a Toshiba Satellite C50-B-15N with Vivid 64, same kernel version as Zacharias, but a Qualcomm Atheros card (Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01), running with the ath9k module). Walter Garcia-Fontes suggested on the linked bug that this new one could be hardware-specific, but here we see that the issue comes up with at least two different brands of wifi cards, i.e. Atheros and Broadcom. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1473088 Title: network manager peap mschapv2 authentication stopped working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1473088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
