No network connections are working

English Network/Internet

A strange thing happened to my laptop: I installed no updates and didn’t make any configuration changes after I booted yesterday (and I had no issues yesterday), and yet this morning when I booted up, I did not have any working network connections. I can’t connect to wifi, and it’s not even connecting to a hotspot on my phone.

I had been affected by the iwlwifi update a few week back, but even with that issue, I was able to connect to my phone’s hotspot.

I tried booting from old snapshots (both pre and post the aforementioned iwlwifi issue), but they all have the same problem. The only thing I did between last night and today’s boot, was charge the laptop while it was off.

When I do ip address show, it shows the following (below the loopback entry):

2: wlp0s20f3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether <redacted>

sudo nmcli dev status
shows:

DEVICE    TYPE        STATE         CONNECTION
lo                loopback   unmanaged  __
wlp0s20f3  wifi            unmanaged  __

The NetworkManager service is active. rfkill shows nothing blocking wifi.
I have an Intel Raptor Lake PCH CNVi on a Dell XPS-15 9350.

I just tried booting from a live USB, and was able to connect to wifi, so it seems to be unique to my Tumbleweed installation, and not a hardware issue. The issue occurs in multiple desktop/WM environments.

Any suggestions on how to further troubleshoot this issue? Any help is appreciated.

I would be inclined to look at the output of rfkill - I wonder if the device was disabled somehow (possibly a keyboard shortcut.

rfkill list shows “no” to “soft blocked” and “hard blocked” on both “hci0: Bluetooth” and “1: phy0: Wireless LAN”.

(I would copy and paste the output, but I am typing this response on a phone)

NetworkManager is treating the interface as ‘unmanaged’. Any config file in ‘/etc/NetworkManager.conf.d/’ (or /usr/lib/NetworkManager/conf.d/) explicitly setting the interface as unmanaged? You can of course override this.

What is reported here?

systemctl status network

Happy update: it resolved itself. I’m not sure why, but this time when I clicked “enable network” it worked. I had tried that before and it hadn’t.

Thanks for jumping in to help. I’ll report back if it happens again.
