Similar behavior, wifi keeps disconnecting and malfunction 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. I migrated to Ubuntu 22.04 which installs Kernel 5.15 then the problems started. I upgraded to Kernel 5.17.4 no improvement I disabled the power save at /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf by passing from 3 to 2 NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave NM_SETTING_WIRELESS_POWERSAVE_ENABLE (3): enable powersave without any improvement nor with Kernel 5.15 nor 5.17.4 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 the kernel to 5.13.19-051319-generic and the problem has disappeared. There is no problem in my airpoint (router) nor my internet access, I have other computers working correctly. In addition the N751JK works correctly when using the Ethernet adapter for the physical cable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968391 Title: Unreliable wifi with loads of CTRL-EVENT-BEACON-LOSS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wpa/+bug/1968391/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
