Network card rtw_8821ce repeatedly stops working on Ubuntu 20.04

sj flag

Hi I have a lenovo ideapad l3340 with installed ubuntu 20.04 with network card rtw 8821ce. I read that a lot of people have trouble installing drivers but that was never my case, which is a bit different.

So after turning on the laptop everything is fine and after about 30 minutes to 5 hours my network card stops responding. Nothing, not even localhost is working, and resetting network manager and so on doesn't help. Only thing which works is to restart my laptop but this is pretty annoying because every day this is happening 3-10 times.

I have had this laptop for about one year and a few months ago I had this problem for about a week and then it stopped happening. I don't know if it was one of thousands of things that I tried or it was pure luck but now it started to happen again and I don't know what to do.

Also after I restart my laptop I often get some errors, everytime a little bit different but something like [3211.826282] rtw_8821ce 0000:07:00.0: failed to poll offset=0x5 mask=0x2 value=0x0 despite this, after restart everything is fine.

And, of course, there's a UEFI update (maybe) that already addressed the issue.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
