[SOLVED] Broadcom BCM4352 WiFi adapter drivers (Dell XPS13 2015)

Alright, I've been using the broadcom-wl driver for my BCM4352 WiFi adapter with Network Manager in GNOME but it suddenly stopped working...
Network Manager is not listing out any SSIDs and I can't manually connect to a specified  SSID.
Any help is much appreciated.

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

32 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

Thanks!

I happen to have the same problem with the same hardware. Did you manage to get past these WLC_SCAN errors ?

Unfortunately no, I've tried reinstalling the entire system and installing fedora instead but the error persists.
Updating to the latest A03 BIOS firmware didn't help either.
My current workaround is a USB WiFi dongle.

Still new to linux, so I'm not sure what happened exactly, but after reading this, I made it work.
I run on GNOME, I use broadcom-wl drivers and NetworkManager.service is started/enabled.

Woah! Thanks man! I got it working again!!!

Summery of the problem for future readers:
Wireless communication features can be disabled on a hardware level.
It is toggled by pressing Fn+PrtScr (next to F12) on the XPS13 2015.

All my previous machines didn't have such a feature..... (facepalm)

Re: [SOLVED] Broadcom BCM4352 WiFi adapter drivers (Dell XPS13 2015)

Woah !!!!!!

THANK YOU guys ! I wondered how those WLC_SCAN errors happened while nothing changed on my laptop, no upgrade or install.
I remember though that I tried to change the backlight, which makes sense I may have missed and put my finger on PrintScr as well.

Note in the firmware I inverted the behavior so that I have to press Fn to trigger these "hardware extension" keys.

Somehow it makes sense with the little antenna on the key, but I supposed an OS function had to be programmed for that.

Again thanks ! And facepalm too...


This should be mentioned in the wiki by the way, as there's no indication anywhere in gnome or rfkill.
