Could not reproduce the issue with 4 additional trials.

@Kent Can you put the logs for when it worked?
I see some complains about AX211 not working with 6.5 when first installed, but after a reboot, it works, but no fixes upstream

My Thinkpad T440p with intel 7260 does not have such issue

Yesterday, my kubuntu jammy upgraded from 6.2 to 6.5; my wifi connects, but it's very very unstable, constant drop connections with ssh, chrome hanged...

Rolled back to 6.2 kernel, which works perfectly.

Motherboard is Asus X670E-F with Mediatek AX211 802.11ax WiFi 6e Module.

dmesg command output

Hi, I have the similar issue.
There is no working wifi starting from 6.5.0-14.
It connects well to the hotspot of my OneplusOne phone but does not connects to my AlexL wifi router network.
I attached the logs above.

Same issue as J. Antonio (#25) describes. Update from jammy 6.2 to 6.5.0-15 causing wifi to be highly unstable. Will drop connection repeatedly (every few seconds), hangs when it is connected. Turning off/on wifi sometimes corrects the issue for a short time. Also happened with 6.5.0-14 - was hoping update to 6.5.0-15 would fix it but it persists.

FTR Kernel 6.5.0-25 fixed the problem for me; using > 2 weeks now.

I posted the previous comment #29 (can no longer edit it) about how previous 6.5 kernels caused unstable/broken wifi.

Prior to the 6.5.0-25 update, was using grub to force kernel 6.2.x so I could maintain reliable wifi. Happily the bug seems fixed now, in my case at least.
