Title:
Wifi randomly disconnects [AR9462]
Status in linux package in Ubuntu:
Confirmed
Bug description:
my hardware : laptop Asus N751JK Network controller: Qualcomm Atheros
AR9462 Wireless Network Adapter (rev 01) Subsystem: AzureWave AR9462
Wireless Network Adapter
I was runing Ubuntu 20.10, 21.04 up to Ubuntu 21.10 with Ubuntu Kernel 5.13.0
without any problem.
When migrated to Ubuntu 22.04 which installs Ubuntu Kernel 5.15.0.x (which
corresponds to Mainline Kernel 5.15.5) then the problems started.
The Mainline Kernel 5.15.4 corresponds to the Ubuntu Kernel 5.15.0-12.12
(date 2021-11-21 13:32:06)
The Mainline Kernel 5.15.5 corresponds to the Ubuntu Kernel 5.15.0-13.13
(date 2021-11-25 09:35:53)
I upgraded and tested unsuccessfully the following Mainline Kernels :
5.15.28, 5.15.36, 5.16.14, 5.16.20, 5.17.4, 5.17.5
I disabled the power save as explained at
https://askubuntu.com/questions/1403773/22-04-wifi-keeps-disconnecting-for-a-few-seconds-frequently/1404471#1404471
without improvement in any of the Kernels tested.
Also the "intel_iommu=off" mentioned at
https://groups.google.com/g/linux.debian.kernel/c/RFpPIp0cncA/m/v9ELDxLICgAJ
Bug#994590 didn't help.
I downgraded and currently running without any problem using the
Ubuntu Kernels 5.13.19-051319-generic or Mainline Kernels 5.15.0 or
5.15.4
There is no problem in my airpoint (router) nor my internet access, I have
other different computers and devices working correctly on wifi.
In addition my N751JK works correctly when using the Ethernet adapter for the
physical cable.
seems to be something between Mainline Kernels 5.15.4 and 5.15.5 that
is also propagated to 5.16.x and 5.17.x
