Fedora 24 was released a month ago, which means Fedora 22 is losing its support. That pushed me to upgrade my box to the next version, which is Fedora 23, which has 1 more year of support. (I tend to use a version previous the latest release for a bit more stability :D) So, yeah, after that os upgrade, which is now easy via dnf, I started to apply fixes to each issue as they came... and continue to come ;)
One of the issues I got was with my Broadcom BCM4350 wireless. My WiFi just went AWOL while I was fixing another issue. HAHA I've always had issues with Broadcom wireliess on Fedora so it's not really a surprise.
Anyway, i tried my previously noted procedure that worked on Fedora 22 (http://linusramos.blogspot.com/2016/03/xps-13-9350-broadcom-bcm4350-fedora-22.html), but it didn't work. The Broadcom card was not detected as a "network controller" So, I tried to refresh the drivers installed. I removed broadcom-wl and restarted my box. To my surprise, my WiFi worked. Yep, just like that.
The following commands now show...
