My wifi connectivity has recently stopped. I am using an HP Probook with elementary OS 0.4.1 Loki.
I use the app manager to maintain my software state. As far as I can tell the device is still there.
It would seem I have a Broadcom card!
I have read a few posts and have run the following the diagnostics.

I have uninstalled & reinstalled bcmwl-kernel-source 6.30.223.271
Any ideas?
