I just found out that my Lenovo dock also affects this situation -- when
I undock my T480, wifi starts working properly. (No, the dock doesn't
have ethernet cable attached.)
Still, I had problems already before starting to use the dock, but wifi
performance was bearable then. With dock it is not.
I have similar problem with similar dmesg output with Lenovo T480 (Intel
8265 wifi) and Huawei router.
The problems started after upgrading from 18.04 to 20.04.1 about a week
ago.

Comment #28 seems to offer some good insights about the best path
forward here, also supporting that this bug should be reopened. Note
that with a Google Wifi router, there is no capability to reconfigure
the router to work around this issue, as the poster mentions.

I have a X1 Carbon 6th gen, kernel 5.3.0-22-generic and the error
remains. I've also tried moving to static channels on my router (1, 6

I am using a HG8245H Huawei router right now. Has anyone with a similar

On my X1 Carbon 4th gen, kernel 5.3.0-22-generic seems to have
completely fixed the issue. Yay!

It is because of the way Intel updated the firmware upstream. The
