no wi-fi on MB

[freshtamatic]

Hi everyone.
I had a Macbook 2008 that was runninmg Manjaro XFCE rather well.
I upgraded its HDD to a Sandisk SSD, that with the 4GB RAM made me confident to try Linux Cinnamon.
I've run into a wi-fi problwm, or the lack of it If you will.
It works fine with ethernet, with wi-fi it sees nothing.
Any magical fixes from you guys?
TIA!

No magic, but post results from terminal for

Code: Select all

lspci -nnk | grep -iA3 net

And I might have some ideas

Try in terminal

Code: Select all

sudo apt update && sudo apt install firmware-b43-installer

Then reboot, see if it works

Jeremy, I am still trying. Boot times have gone to 1/3 of the speeds I was getting with Apple's HDD. I just bought the SSD today, so I can't understand it.
As soon as I have the results, I will update you.
Thanks!
