Hi all, after flashing EndeavourOS (i3wm) onto a Dell XPS 13, the WiFi doesn’t connect. After running lshw -C network, the wireless internet driver is marked with “UNCLAIMED”, which from my research means the drivers aren’t installed. However, I’ve followed the instructions on the Arch Wiki and installed linux-firmware.
I’m not sure how to fix this, feel free to ask for additional information!
Does it still show as unclaimed?
Edit: also what command did you use to install linux-firmware?
Yes, it does.
I used sudo pacman -S linux-firmware, it’s in the official repo so I assumed that’s what I had to do.
Do you have brcmfmac4350-pcie.bin inside /lib/firmware/brcm?
Edit: btw this thread seems very close to what you’re experiencing, just with an older model
I have /lib/firmware/brcm/brcmfmac4350-pcie.bin.xz, not sure if that’s the same thing.
Weird that it still didn’t load after a reboot. Hopefully someone more knowledgeable can chime in.
Another detail is that for some reason after running lspci -nn, the PCI code for what’s probably the WiFi adapter is 14e1:8100, which doesn’t look right.

Also, I just realized that after running sudo lshw -C network, the wireless connection has disappeared (I only see the Ethernet one that I connected over USB-C)
Do this:
Shutdown your computer, then turn off all power supply (if on a laptop unplug the battery) for at least 30 seconds. Then power back on and run the same commands again, please.
By “unplug the battery” do you mean disconnect the charging cable, or take apart the laptop and remove the battery?
Remove the battery. There are chipsets, that are cheap and carry bluetooth functionality with them that sometimes require this.
But…
…before you have to do that, please post your inxi -Fxxc0z | eos-sendlog
It shows the device isn’t up, and BT is on a different chipset.

So it must be a missing driver-issue (and you don’t need to take out your battery!) 
Yes, that’s what I suspected in the beginning. And whew, disaster averted lol.
But from what I’ve read, linux-firmware should have the required drivers. I also have broadcom-wl-dkms installed. What else would I have to do to get them?
Just came across this: The Dell XPS 13 seems to have a hardware-switch for WiFi (Fn + F2 button)?
As such things many a time get overlooked, could it be that simple?!
That might be on another model, Fn+F2 for me is volume down. I wish it were that easy though!
F2 alone, or Win + X ?
Also, someone disabled their BT in the BIOS settings to get it to work. - Speaking of BIOS, you might want to look into a BIOS update, which potentially could fix things.
Are you dualbooting with Windows?
I’am asking because it happens that Windows may “hijack” the wireless card if it has fast startup or hibernation enabled.
I’m hoping pebcak is right because I got stuck at that same step yesterday. The wiki page for those drivers was describing:
“Copy brcm/bcm43xx-0.fw and brcm/bcm43xx_hdr-0.fw to /lib/firmware/brcm (or wherever firmware is normally installed on your system)”
But it didn’t make a whole lot of sense to me.
