Can you try booting into a previous kernel before we try something else, you should be able to from the grub select which kernel you want to boot.

 

[begad]

wdym?

 

[f33dm3bits]

wdym?

Translation?

 

[begad]

i mean what do you mean do i turn the pc of and reopen it or what?

 

[f33dm3bits]

Yes restart your system, then you should see the grub menu, select Advanced and then boot the previous kernel from there. See attachments, except for I only have one kernel installed because it's a fresh install.

 

[begad]

ya i tried the old kernel before it didnt work

 

[f33dm3bits]

I forgot that broadcom drivers aren't opensource, can you try removing.

sudo apt remove bcmwl-kernel-source

Then reboot and install this.

sudo apt install broadcom-sta-dkms

And share the output of.

ip a
