I am having some issues with wifi on essentially a brand new computer (Lenovo Thinkbook 13s, about two months old, ubuntu 22.10) and figure it shipped with a defective wireless adapter since every once in a while it will stop being recognized and not even show up on lspci (usually after one of ubuntu's hard crashes while waking from sleep which are frequent on this machine). It's a dual boot and sometimes won't even show up in windows, so I figured it must be a hardware problem.
My solution was to buy a cheap USB wireless adapter (Ralink MT7601U) which was advertised as being compatible with Linux. All the prior threads I have seen regarding this adapter are very old and it appears the driver has been part of the kernel for a long time now. It didn't work out of the box (came up on lsusb and could display networks, but couldn't connect) but after some messing around with it, it finally started working, though I'm not sure exactly what fixed it. Now it is working sporadically but will sometimes go back to displaying networks without being able to connect.
Airplane mode is turned off, the network password is correct, have tried turning it off and on again. Anyone else have this issue or any ideas?

EDIT: I should add that I can USB tether to my phone with no problem.
