Wifi Connectivity issues <SOLVED!!!>

Post by kroggan »

I just made a clean installation of Linux Mint MATE 20.2 Uma 64-bit
It's Kernel is : Kernel Linux 5.4.0-90-generic x86_64
And MATE is : MATE 1.24.0

Till earlier this morning the Wi-Fi was working completely fine, I have just recently installed libicu66 security update this morning.
I can't connect to my Wi-Fi network, when hovering the mouse over network icon on taskbar it says configuring the xxx network and in the connections it shows connected but then it disconnects and i can't access internet in the meantime (i.e. it shows connecting indefinitely and then disconnects).

The follwing commands give:

Thanks in advance. :)


EDIT: I have tried many other solutions posted on the forum but none of them worked.

EDIT: I am a total newbie green user, and have had only a limited contact with ubuntu and understand how to operate the terminal and browse the file system with it and that's it!
EDIT: The name of the update was icu and its origin was Ubuntu/focal-security

If you have one, restore a Timeshift snapshot. Then test whether the culprit really is the package that you suspect. If so, restore the snapshot again and blacklist the offending update.

Furthermore, whatever you do, also do this:

Do I restore the original timestamp the second time?
Also, how do I blacklist the "offending update"?
Do I need to reboot after the first timestamp restore?

:)

EDIT: It really was the update.
After restoring the timestamp my wifi started working smoothly.

If I recall correctly (can't test it right now), right-clicking that update in Update Manager should give you the option to blacklist it. Roughly that approach; in any case, it's not complicated or hard to do. :)
