Wifi misbehaving

I’ve got Realtek RTL8822BE 802.11q/b/g/n/ac WiFi adapter, rte_8822be driver on my laptop. Sometimes wifi just turns off saying ‘disconnected’, while inxi -N still shows both ethernet and wifi drivers present. Other times wifi adapter just straight-up disappears. Sometimes a few resets fix the problem.

Have you tried upgrading to 5.4 LTS (Long Term Support) or 5.10 (LTS candidate) yet?

:crossed_fingers:

i upgraded to 5.11 hoping it would fix the issue lmao

it used to be 5.10

Had a similar issues with a realtek card on one of my desktop machines. Nothing would fix it, tried 4 or 5 different kernels, manually compiling drivers, etc. It was a usb wifi adapter, but i’m pretty sure it was the same driver (I’ve slept since then)… Anyway, I know it’s not a fix but I ended up getting an intel card and problem went away.

Yeah, that sucks
Don’t think you can switch a wifi chip in a 4-year-old laptop though

Can you try both:

  • linux54
  • linux54-rt

Please?

Yes you can, because Intel UEFI drivers are generally included in Intel Core i5-8250U machines. but before we go down that road, try the above first.

:crossed_fingers:

Seems like a new version of Realtek drivers that just came out and fixed the problem on kernel 5.11.

havent changed it yet, still 5-11

You’re lucky I’m an editor here, so I’ve edited that crucial information into your answer so that the next person that has the same problem as you won’t have to read the entire thread but see the following at the top:

Next time please do that yourself by clicking the 3 dots below your post and pressing the pencil as I won’t be trolling all of your posts and fixing them for you all of the time!

:grin:

ah, sorry, didnt get it
