I reverse bisected the upstream kernel, and determined that the fix is in commit 16c426f. I also believe that this is (upstream) already set to be merged into the 3.19 kernel (please let me know if that's not the case).
Specifically, there is only one small change in this commit, which adjusts the way the shared bluetooth antenna works. Inspecting the code, I also determined the following test and workaround - turn off the bluetooth, and then restart. I attempted this on the latest Ubuntu 3.19.0-15-generic kernel. If the computer is booted with the bluetooth turned off (i.e. from a previous session) then the wifi will work. If the computer boots with the bluetooth turned on, the wifi will not work, even if you first turn off the bluetooth. A restart is needed. Let me know if there is more I can do. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1442411 Title: Intel 3160 wireless card no longer able to connect to wifi networks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442411/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
