No wireless after new install (card is Broadcom BCM43142)

Post by jmelton » Tue May 01, 2018 8:09 pm

Put a new SSD in my old Dell Inspiron 3520, and although my wireless connected just fine from the USB stick I was installing from and it appeared to install everything perfectly, when I reboot I have no wireless access or even detection of wireless capability when I click on the network settings icon. But lspci shows both the wireless (Broadcom BCM43142, a.k.a. DW1704) and ethernet cards. I have wired access, and wireless still works fine when I boot from my old disk, which is now in an external case. Is the kernel that comes with version 18.3 one that won't work with my card?

Update: I fixed this issue from the Driver Manager by selecting the bcmwl-kernel-source option. (I assume that's the name of the driver?) I thought I'd leave the post up in case it might help someone else. Now to figure out how to get it working in my other distro, Elem. OS.

in Cinnamon the driver manager can be found in Menu>Administration. Our you can install it via the terminal with this command

Code: Select all

if you do not have internet access follow the instruction on this page:
