Public bug reported: 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. In addition my N751JK works correctly when using the Ethernet adapter for the physical cable. seems to be something between 5.15.4 and 5.15.5 that is also propagated to 5.16.x and 5.17.x (started at https://bugzilla.kernel.org/show_bug.cgi?id=215918) ** Affects: kernel-package (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970965 Title: Wifi randomly disconnects [AR9462] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kernel-package/+bug/1970965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
