** Description changed: - (started at https://bugzilla.kernel.org/show_bug.cgi?id=215918 where log - files were attached) - 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 Kernel 5.13.0 without any problem. When migrated to Ubuntu 22.04 which installs Kernel 5.15.5 then the problems started. I upgraded and tested unsuccessfully the following 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 Kernel 5.13.19-051319-generic. Kernels 5.15.0 and 5.15.4 also runs ok There is no problem in my airpoint (router) nor my internet access, I have other different computers and devices working correctly on wifi.
