I moved and noticed this problem went away with a different router (SAX1V1K) even on the older kernel.
The other network was a eero mesh - so there was like two WAP devices that I guess are same SSID or something, and maybe it was bouncing back and forth between them (poorly?). I don't know if other devices in the house had the problem, using the newer kernel seemed to help so I had assumed it was something weird about the hardware in my IBM x1 5th gen thinkpad, but maybe it's just hard to get mesh networking right and I was just sensitive to the interruptions on my work laptop. -- 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: 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 (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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1970965/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
