After a recent upgrade noticing wifi disconnects randomly, speeds vary
back and forth from 0.1Mbps to 100Mbps within a few seconds, can be up
for a few seconds, or a few hours, not predictable.
This might be some relevant information, but I looked through the
modules and don't see anything like `rtw_8821ce`, there are `rtw88_*`
modules which might be relevant, but in any case I can't map these to
any packages as far as I can tell.

This was the best reference I can find: [WiFi frequently and randomly
disconnects, rtw_8821ce driver][1], but even though it's in the "Newbie
Corner" section, I'm not able to follow what they're doing. Like "Have
you tried connecting with just wpa_supplicant (and a DHCP client if
needed)?" is way over my skill level.

This is the relevant output from `iwconfig`, I had just rebooted, as
that sometimes helps for a bit, so the stats might not be
representative:
```

And another output a few minutes later:
```

And after a few hours, note the speed looks really good, but the
connection isn't working. I'm running off a hot spot now.
