** Description changed: 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 Kernels 5.13.19-051319-generic or 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 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) + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu82 + Architecture: amd64 + CasperMD5CheckResult: unknown + DistroRelease: Ubuntu 22.04 + InstallationDate: Installed on 2021-02-21 (432 days ago) + InstallationMedia: Ubuntu 20.10 "Groovy Gorilla" - Release amd64 (20201022) + NonfreeKernelModules: nvidia_modeset nvidia + Package: linux (not installed) + Tags: jammy + Uname: Linux 5.15.5-051505-generic x86_64 + UnreportableReason: The running kernel is not an Ubuntu kernel + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: N/A + _MarkForUpload: True ** Attachment added: "ProcCpuinfoMinimal.txt" https://bugs.launchpad.net/bugs/1970965/+attachment/5585193/+files/ProcCpuinfoMinimal.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1970965 Title: Wifi randomly disconnects [AR9462] Status in linux package in Ubuntu: Incomplete 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 Kernel 5.13.0 without any problem.
