Cannot connect to wifi using iwd

normalaccount · 2020-12-31 18:45:18

Hey,

Been using Arch for a couple of months and for the last months, I was able to connect to a single network using iwd. I was only able to connect to one network and had issues, so I'm trying to fix it now but I don't have access to the wifi at all now.

I can connect to networks using iwd, but I don't have access to the wifi which is weird. Per example, pinging Google will return a failure in name resolution even though I'm connected to my network.

I thought it was a driver issue, so I downloaded the driver files for my ax200 card on the Intel site and pasted them in the /lib/firmware folder. That didn't help.

When I do the "ip link" command, wlan0 shows up also the interface even though my interface is wlp59s0 as shown on Ubuntu.

Any help would be appreciated. I've reinstalled iwd, I've made sure that no other conflicting network backends were in use, but nothing seems to work so far

Sounds like you haven't set a nameserver: https://wiki.archlinux.org/index.php/Do … resolution

That is expected and set by usr/lib/systemd/network/80-iwd.link

Thanks for the answer. I've set a name server using the systemd-resolved default configuration with NetworkManager and /etc/resolv.conf returns the following lines:

"# Generated by NetworkManager
nameserver ::1
nameserver 127.0.0.1"

However, pinging returns the following error:

"Name or service not known"

Any idea on how to fix that?

You should explain exactly how you did that instead of vaguely describing it.

The recommended mode of operation for systemd-resolved is to symlink /etc/resolv.conf to the stub resolver:

# ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

NM should automatically use systemd-resolved if this is done, at least according to the ArchWiki.

Personally I prefer to list the desired nameservers explictly in /etc/resolv.conf (ie, without a symlink). If you want to do this with NM then see https://wiki.archlinux.org/index.php/Ne … esolv.conf
