Tried using this: Installing Broadcom Wireless Drivers, but the [14e4:43a3] (rev 08) isn't listed.
Here's the pertinent output from:
sudo lshw -C network
*-network UNCLAIMED description: Network controller product: BCM4350 802.11ac Wireless Network Adapter vendor: Broadcom Limited physical id: 0 bus info: pci@0000:3a:00.0 version: 08 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: memory:dc400000-dc407fff memory:dc000000-dc3fffff
I thought it was a kernel issue, but output from:
The wireless was working recently, but between updates I think something happened.
Any thoughts? I tried running through https://help.ubuntu.com/lts/ubuntu-help/net-wireless-troubleshooting.html, but to no avail. Thanks for any help.
Per request, the output of:
dmesg | grep brcm

sudo dpkg -s bcmwl-kernel-source and got:
dpkg-query: package 'bcmwl-kernel-source' is not installed and no information is available Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents.
I Ran the purge anyways.
Really not sure what I did, but it's working now. Maybe I made a change before all of this, and it just needed the reboot?
Anyways, thank you for the help and I hopefully wrote up something in case someone else has the same issue.
