The next thing would be to test the latest upstream kernel with the newest (-17) firmware. If that fixes the problem we can try to find the fix and backport it to xenial, otherwise we know there's a firmware regression that should be reported to Intel.
Please install the kernel from the link below and let me know how well it works. http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7-rc7/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602051 Title: 5Ghz link no longer works on 16.04 - iwlwifi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1602051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
