Ubuntu 20.04LTS: Ralink RT2561/RT61 keeps deauthenticating

Question

Recently backed up the home folder from a 16.04 LTS install, wiped the disk and did a fresh install of 20.04 LTS, and restored the home folder from the backup. Since then, wifi connects but is slow and regularly drops authentication.

I've tried reloading the wireless kernel module, changing the wifi powersaving settings, and deactivating the N-mode of the driver, with no results.

I think I might need to either recompile the wifi drivers or adjust the kernel version, but I'm not sure which, and I'd rather not touch the kernel if I don't have to. Can anyone offer any insight into which one is likely to be the issue?

Was there only your personal data in that directory or may their have been some system data in it that could be the problem? — David, Oct 03 '21 at 05:43
@David I copied the whole home directory, including hidden folders, so it's possible it could be affected by some system data. Any in particular that I should check? — Boxbot, Oct 04 '21 at 06:19
Have you examined the logs on your wireless AP? Is it receiving the authentication attempts? — James S., Oct 07 '21 at 19:40
I am noticing a discrepancy in the width output of sudo lshw -C network . The width of your ethernet interface is 64bits. The width of the wireless interface is 32bit. I think this could be contributing to your problem. When I ran that same command all interfaces show 64bit. — , Oct 09 '21 at 14:41
Try reinstalling the drivers of ralink using the github page that will definitely help. — Error404, Oct 10 '21 at 02:48
@TBr Is that something I can change on the wireless interface end or the network settings end? I suspect the Ralink is old enough that 32bit is its limit. — Boxbot, Oct 11 '21 at 09:12
@JamesS. As far as I can tell, yeah; I'll take another look just to be sure. — Boxbot, Oct 11 '21 at 09:12

The only way I could see making a change from 32 bit to 64 bit is through a driver that is 64 bit. Again it's just something I noticed but may or may not be contributing to your issue. — , Oct 11 '21 at 16:19
Here's a related question but it refers to ubuntu 16.10. https://askubuntu.com/questions/839479/ubuntu-16-10-wifi-trouble-rt2561-rt61 I'm not sure if anything there will help in your case but could be worth looking at anyway. — , Oct 11 '21 at 16:28
This may actually help, it's in regards to a similar issue with a different wireless card for 20.04. https://askubuntu.com/questions/1230140/wifi-keeps-dropping-out-ubuntu-20-04-and-broadcom-wireless-adaptor?noredirect=1&lq=1 — , Oct 11 '21 at 16:45
