Hello Leirundo,

in order to help you, we need informations of your system and especially of your wired/wireless cards. Can you please open the terminal (Ctrl+Alt+T) and run the following commands:

Code: Select all

inxi -Fxz
(if typing, the F is a capital letter)

Code: Select all

lspci
You can highlight the results in the terminal and with the mouse right-click menu, you can copy & paste it here. For better readability you can highlight the pasted results here and press the </> button above the text box, so they will appear in codeblocks.

Hello Leirundo,

until now the only thing is, that the 5.3.0-26 kernel, which causes many issues, is the culprit for your problem. Can you try to boot with a previous kernel? Reboot and go to the "Advanced options" in the grub menu, choose the previous kernel for start and see, if wifi is back again in Linux Mint.
