WIFI suddenly disapperead (3days after installation) [SOLVED]
« on: January 02, 2019, 12:12:50 pm »
Hello there.

I'm completely new to linux and recently bought a cheap windows 10 notebook to get started with it, and was delighted by Peppermint during the first few days.  Great work!  However, now I have a chance to learn more about the working of this operating system because for no apparent reason to myself, the WIFI doesnt't work on the third day.  It's a few days since the occurunce; I have started to understand more about linux and the terminal and have read around various forums but i feel like Im completely new to it and I need to ask more experienced people who can read the output from my terminal, and hopefully guide me on the way to more knowledge of this problem and eventually to fix it. Can anyone guide me in the right direction?

Hi Hek,

Welcome to the forums

You need to encapsulate the terminal output with the Insert, Code # function.  For extra long outputs, please use the Spoiler, Sp function.  If youíre a Chromium Browser and/or a Google Chrome user, please don't combine these functions.  For some reason, they donít work well together with these browsers.  The formatting gets all goofed up.  Only use one or the other  ;).  These forum functions preserve the original format of the output.  This makes it easier for future visitors to relate to their own issues.  These functions are found in the forum editor, above the,  :-[ Embarrassed and  the :'( Cry emoticon respectively.  Use the Preview button to check how it'll look after you post it to forum.  I hope this helps  ;)

I have done it for you this time

Regards Zeb....

ps answers to your problem should arrive soon :)

Do you get any output from:
Code: [Select]
lsmod | grep r8822be
if not, does wireless spring to life if you run:
Code: [Select]
sudo modprobe r8822be

Okay, try disabling "secureboot" in your BIOS.

I'm guessing there's been a firmware update and the new firmware for that hardware isn't signed.

That's done it!  WIFI is working again, thanks a lot!

For reference it's a HP Stream 11 laptop.

Thanks again!
