Same issue here.
Did you find a solution? Im on pop_os as well.

[TheGreatHalva]

nope. using built-in driver right now, but the performance on my TP-Link adapter is far from good.
funnilly enough, this driver worked perfectly on arch. may this be one of ubuntu-specific bugs?

+1 Manjaro with kernel 5.10.42

Same here

Same with Debian11 on kernel-5.10.0-9.
Nobody solved this yet??? older version on kernel-4 was all fine
