[Kernel-packages] [Bug 1746164] Re: Enable Bluetooth-Wifi coexistence by default [bluetooth audio and network skip on Wifi activity]
Right. So we agree your patch should be applied by default to ath9k. Just as coexistence is enabled by default for Intel wifi.

[Kernel-packages] [Bug 1746164] Re: Enable Bluetooth-Wifi coexistence by default [bluetooth audio and network skip on Wifi activity]
The user won't probably want to do that: - The new default reduces the Wifi Speed only while bluetooth is actually trying to send (which isn't too often if the user isn't currently listening to Bluetooth audio) and - If Bluetooth/Wifi coecistence isn't enabled Bluetooth (when trying to send on the same frequency as the WiFi) tends to make the Wifi packet impossible to read => The WiFi packet has to be retransmitted => WiFi might get even slower than with Bluetooth-WiFi coexistence enabled. - Also since I have enabled Bluetooth-Wifi coexistence my wifi connection has stopped dropping from time to time => my guess is that if Bluetooth can send while WiFi does, this destroys packets and this happens to happen with every packet for a while the connection WiFi might drop as the Bluetooth one might in this case. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1746164 Title: Enable Bluetooth-Wifi coexistence by default [bluetooth audio and network skip on Wifi activity] Status in bluez package in Ubuntu: Invalid Status in linux package in Ubuntu: Confirmed Bug description: By default BT audio works fine on Ubuntu - if there is no WiFi active: Both work on the same frequency range, 2 WiFi channel is about 20 Bluetooth Channels wide and every time a WiFi package is sent bluetooth risks a packet loss.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
