I have a huge problem. I can’t connect to wlan0, my WiFi, whether on my Live USB or on the actual installation itself. Strangely, I could connect to the internet using iwctl on Arch Live USB, but not on EndeavourOS for some reason, even though EndeavourOS is literally just Arch on easy mode, so anything Arch will apply here, right? Because I coudn’t connect to the internet on my Live USB, I was forced to install Endeavour OS with the offline method with XFCE and Endeavour OS theming. When I tried ip link, it only showed the ‘lo’ connection and the ethernet port. No ‘wlan0’, which means Endeavour can’t recognise my router. It should be noted that I am pretty new to this. The only way I’m forced to connect to the internet on Endeavour OS is through iPhone USB tethering and that’s annoying. Any help is appreciated. TY
welcome at the forum 
To see what is the issue it would need at least any info about teh hardware…

The reason you’re seeing Apple Mac as my host is because I’m dualbooting Endeavour OS and MacOS, just to let you know.
please use code tags…
could be you have to remove broadcom-wl package.
can work on live usb too
sudo pacman -R broadcom-wl-dkms
sudo rmmod wl
sudo modprobe brcmfmac
sudo systemctl restart NetworkManager
wait should I run the thing again but with root?
it worked tysm. I rlly appreciate the help.
Alr, but Ihave another problem. iwctl doesen’t work. When I try running it, it says ‘Waiting for IWD to start…’ but when I write ‘sudo systemctl start iwctl’, it says: ‘Failed to start iwctl.service: Unit iwctl.service not found.’ Strange.
we have NetworkManager enabled by default… not sure if they can be used side by side?
NetworkManager ships with nmcli and nmtui plus it is integrated in almost all DEs
Why do you need iwd? As @joekamprad said already has network manager. According to Arch WiKi, one can use iwd and any other network manager side by side. But why?
but i bet you can not use them both enabled at the same time…
And i bet user is simply only try to find the tool to setup wiereless connection and stumble over iwd…
Yeah, can’t have two wives in the same kitchen 
Only a problem if they’re both yours?? 
Well, one would be current the other would be my used-to-be current. (hypothetical, I’m still single.)
There are those who contend that the hypothetical kind of wife is the BEST kind…
Nope - not going there!
