Wifi broke after updating

Post by markusviktorius » Thu Aug 22, 2019 1:19 pm

Hi,

Installed 19.2 the other day with wifi working and all.
Updated through update manager, rebooted and then wifi wont show up.
Thought it had something to do with the latest RTL8111 driver.
Reinstalled 19.2 and wifi works. WITH the latest driver.

Dont know how much of the other posts about a broken wifi will apply to my problems as i dont want to loose my wifi as of now.
Anyone have a clue?

It's strange.... You might benefit from freezing your current kernel and firmware:

Code: Select all

sudo apt-mark hold "linux-generic*" "linux-headers-generic*" "linux-image-generic*" "linux-signed-generic*" "linux-signed-image-generic*" linux-libc-dev linux-firmware
This shows the frozen packages:

Code: Select all

apt-mark showhold
(no sudo needed)

If you wish to undo the freeze:

Code: Select all

sudo apt-mark unhold "linux-generic*" "linux-headers-generic*" "linux-image-generic*" "linux-signed-generic*" "linux-signed-image-generic*" linux-libc-dev linux-firmware

Thanks for the tip. What do i lose if i do this freeze?
Would you know what package that could have been the culprit when I updated?

Probably the -58 kernel (4.15.0-58.64) or the linux-firmware package 1.173.9. Kernels and firmware are the usual suspects for things like that.

By freezing your kernel and firmware, you eliminate that risk. At a price, of course, but usually that price is acceptable (definitely so as temporary measure).

Last time i did a snapshot before i updated but the wifi-option still was not avaliable (only wired).
Im afraid to do a snapshot again and if i update wifi will be broken again even if i revert to the snapshot.

Would you know why the issue still persisted even though i went back to the snapshot?

No, that's even more strange. Check the settings of your WiFi network; it should have the following characteristics:
- WPA2 Personal
- AES only (no TKIP)
- SSID visible (not hidden)
- optimal wireless channel for your situation, preferably fixed (not automatic/dynamic)

Good to hear! With a bit of luck those updates may have solved it.

You're welcome! I started it in 2009, so it's a decade of work. If it's your hobby, you don't count the hours. :)
