Back over on the MBP 5,4 Manjaro MATE edition, tried to find “lib/firmware/b43” and it isn’t in there?? I checked Add/remove and I see that b43-fwcutter is installed (wasn’t sure, since I added and removed it with the other package). I did see a “brcm” directory, but no “b43” itself, although I did search “b43” and it showed “firmware” as its location, but couldn’t actually navi to it…
Other issue, trying to just add in your “b43-firmware” package . . . I don’t know what a “yay” is, if that means just run “sudo aur-helper” then that might be easiest?? I searched Preferences >>Third Party . . . and in MATE there is nothing in Preferences that says “Third Party”?? I opened a number of options in Preferences and didn’t see “Third party.”
So, it seems like the solution should be at hand . . . “we” just can’t get it done as of yet.
Open ‘Add/Remove Software’ (this app is the GUI of pamac) >> Preferences > > Third Party and activate AUR Support. Then search in Add/Remove Software for b43-firmware and it will be there.
Success!!! I thought you were talking about “System Preferences” rather than in the Add/remove app . . . . So, indeed, after adding Third Party support the “b43-firmware” package appeared and installed it . . . . Shut down and on cold boot “enable wifi” is now checked on and I was able to add the wifi connection to type this post.
That now makes the Manjaro system “operational” for a laptop . . . thanks kindly for your patience on it. I just haven’t had to mess with my other Manjaro install other than routine pacman upgrades, so never had any need to get under the hood on any of it, so I had no clue how to go about getting it done. Again, a tad bit odd since the desktop machine has the same wifi card and it set up wifi on the install, never had to do anything there either.
