Here is something I did to temporarily fix a WiFi problem I currently have if anyone is interested.
I couldn’t use driver manager in Mint. No Internet connection on Mint because of broadcom card. Couldn’t connect to router (too far from my position at present}. I think I ran driver manager in Mint 18.3 through its auto sequence but broadcom still didn’t work, unless I missed something doing it. I don’t know mint much, first time using it. So I tried an experiment. I used time-shift to restore Ubuntu Mate ( both system and home) from an external HDD on the mint machine and it worked and works well so far. Now I have two machines with the exact same operating system on them, password and all. The only thing is it left mints home folder behind in Ubuntu’s home folder which to me is no big thing, just a little less drive space. Now, I can delete the mint home folder as “sudo” or just leave it alone. Till then I’ll get another computer which I’ll re-install mint on then.
Oh, I connected an Ethernet cable between both laptop computers, the Acer computers wifi quit working, which I didn’t expect, so I connected both computers via “Shared to other computers” method under ipv4 tab. The other computer is the server and the Acer computer is the client. Now the acer can connect to the Internet from the other computer through the Ethernet the cable connecting to both computers.
