Broadcom wireless issues with Fedora 27 wl.ko exists but not detected by modprobe

asked 2017-11-14 09:54:27 -0500

I just installed Fedora 27 and installed broadcom-wl from the rpmfusion non-free repository. I then upgraded my system's packages with sudo dnf update -y (as broadcom-wl was built for a newer kernel than the one I had freshly after installing F27) and rebooted. When I logged in I noticed something bizarre there was no WiFi icon in the menu at the top-right hand side of the screen (where Battery, volume, bluetooth, etc. options appear). Running nmtui (after installing NetworkManager-tui) also does not show any WiFi option either. I verified that broadcom-wl was installed with sudo dnf install -y broadcom-wl and it was. I then ran sudo modprobe -a wl and it returned:

modprobe: WARNING: Module wl not found in directory /lib/modules/4.13.11-300.fc27.x86_64


find /lib/modules/4.13.11-300.fc27.x86_64 -name "wl.ko"



so clearly something is up with the Broadcom wireless as the module exists but it's not detected by modprobe. Any ideas what the problem is?

Is there anything in dmesg or journalctl -b output about this issue?

That message from modprobe is a warning. I think that means it found the module somewhere, but not where it expected it. If it couldn't find it at all, it would give an error message instead. Does lsmod show the module loaded? Try running depmod -a. Also, as mentioned earlier, check the journal for more info on what's happening.

That (depmod -a) worked perfectly, running afterwards modprobe -a wl caused my WiFi to work, thanks!
