Thank you for the workaround.

Just tried the mainstream kernel "4.10.0-041000rc5-lowlatency" as mentioned above and I do confirm the very same problem exists there too. Just to give a hint - this regression was introduced approximately in the first two weeks of 2017, so it shouldn't be that difficult to trace back the change, which could then point to the actual root cause. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1658016 Title: Intel AC7260 wireless (iwlwifi) stops working after computer sleep/wakeup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1658016/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
