It sounds like maybe @peterpall isn't doing what @kaihengfeng asked: btcoex_enable=0 bt_ant_diversity=1

Actually it sounds like the fix @peterpall needs is just: btcoex_enable=1 Which is what the title of the bug says too :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746164 Title: [ath9k] Enable Bluetooth-Wifi coexistence by default (bluetooth audio and network skip on Wifi activity) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746164/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
