[SOLVED]BCM43142 Wireless Invisible to Mint 19.1 on Inspiron 7347

Post by Grail Arnica » Sun Jun 02, 2019 11:15 pm

Finally thought I'd jump to Linux Mint-the old Dell Inspiron 7347 was choking on Windows 10. Did an OEM install from USB with no problems until...yes, there is no way to connect to the Internet but through the now-invisible Broadcom wireless adapter. I've tried reinstalling the bcmwl-kernel-source twice now, with reboots, but the adapter remains invisible. I've tried most of the command line recipes in this forum with no success. Anything you can do to help would be great.

Nothing yet...waiting on dongle...

I did work through the suggestions one by one, except for the obvious (no Ethernet connection available, this is not a dual-boot setup) and did get to finally SEE a Network Settings/Network Connections dialogue when I hit the icon in the system tray.
I choose to call this progress, and it makes me feel as though this situation is not insolvable.

So, not a SOLVED yet...

Thanks for the excellent reference, though...!

Re-worked through ALL the suggestions that applied (nothing that required Ethernet connection, obs, because there ain't one)...and finally up on wireless! Hard to say WHICH solution worked, I think it was several in combo with repeated sufficient warm boots...Good luck to all those who haven't had it work yet, if I was able to get this brain-dead little Dell Inspiron i3 to work, I know you'll be just fine...

Good, I guess it doesn't matter what worked as long as something did. :)
