WiFi cuts in and out randomly

I’ve installed Manjaro 20 Plasma onto an HP ENVY x360.
The WiFi has started to drop to 0 bytes up/down without disconnecting, at seemingly random intervals.
Sometimes it’ll drop twice in five minutes, sometimes twice in five hours.
It’s not yet happened during a Zoom call, although it has happened during Chromium file downloads.
Disconnecting and then reconnecting from/to the network can stop it temporarily.

I’m not sure how to diagnose this, so here is the output of some hopefully relevant commands.
Thanks in advance for your support.

First step is to upgrade to Kernel 5.9, 5.8 is at end of life, then recheck.

Oh I didn’t realise I was still on 5.8. I’ll change that and report back.

It doesn’t seem to be as horrible on 5.9 but it definitely persists.
Hopefully the various network/driver changes in 5.10 fix it.
Until then I’m open to other suggestions.

Are you using bluetooth at the same time?

My Bluetooth’s been disabled.

I suppose you could try GitHub - lwfinger/rtw88 it is in the AUR. You will need to install DKMS and Kernel Headers for your kernel/kernels.

This is assuming that there is nothing in the surrounding area that is causing interference. You can also change the transmit channel from your router and see if that helps.

My Windows desktop’s fine with it, so it’s likely not outside interference. I’ll look into the dkms module, good thing it’s in the AUR. Thanks :slight_smile:
