Newtork interfaces not workingafter install [SOLVED]

Hi,
I installed ArchLinux alongside WIndows 10. During installation, the WiFi interface was available and working. After install and booting into KDE, the network interfaces are all down and not working. Can you help me with that please.

Thanks

Re: Newtork interfaces not workingafter install [SOLVED]

did you forget to install linux-firmware? most if not all of the current wifi drivers/firmwares are in that package.

I started learning linux under Debian, and this is what I hope for every time I interact with the awesome Arch community.

Did you enable anything that would handle the network? The interfaces are present but it just looks like don't use anything to actually make use of them.

No, it's installed, version is 20210919.d526e04-1.

I tried using iwctl, but it just hangs with message "Waiting for IWD to start...".

I also installed dhcpcd during install, and can connect to a wired network, but when trying to connect to WiFi I get a timeout.

You need to start/enable iwd if you intend to use it.

I did that, then used iwctl to connect and it works! Thank you very much.

I also added the following lines to /etc/iwd/main.conf:
[Settings]
AutoConnect=true

as I read that's needed for auto connect.

However, before that I tried using wifi-menu, and it fails every time. I find it more convenient than iwctl. Can you please suggest what can be done in order to get connections with wifi-menu?

Then you'd need to disable iwd, potentially remove the package and instead set up netctl: https://wiki.archlinux.org/title/Netctl
