Network suddenly unmanaged

[TomDalla]

The network suddenly decided to stop working on my Manjaro KDE laptop.
I was surfing the web when suddenly the network interfaces seem down.

This is what the network icon looks like now (toggling the Wi-Fi icon doesn’t do anything):

I wasn’t installing or updating anything, and haven’t updated packages in couple days.

A few nmcli commands to illustrate the problem:

    ~  nmcli dev set wlp1s0 managed yes                                                                                                                                                                                 ✔  root@yoga

Any idea how can I get the network back?
I tried previous kernels as well as the fallback ones without luck (same issue).
It’s not a hardware issue as I am currently posting this from my Windows dual boot on the same laptop and the wifi still works fine.

Have you tried?

No wifi visible or can connect to any wifi unless I restart my pc

Edited the OP for proper inxi information formatting. If you have tlp installed, you can remove it and see if the issue persist, or keep it and disable power management on that USB port the wifi is connected to. tlpui can give a graphical interface for that. Also make sure is not a USB3 port. You could disable MAC address randomization in /etc/NetworkManager/NetworkManager.conf and change it to have this lines: [device] wifi.scan-rand-mac-address=no save it and then run from terminal: syst…

Frequent wifi disconnects after updating to 21.2.3

While I understand perfectly, using an LTS kernel might be the only thing that works. LTS stand for Long Term Support, so contains more bugfixes than others. Therefore, it might contain newer, updated drivers for the card that a normal kernel doesn’t. I have seen many problems with this specific adapter, and while I can’t remember the exact solution, I think it was using a different kernel. Edit: This page on the Archwiki had this to say about the Intel Wi-Fi 6 AX200: For models with the …

Yes, none resolved my issue.

For the first one, the wifi is not DORMANT like the person in that thread. It’s already DEFAULT (and DOWN):

 ✘ uzer@yoga  ~  ip link

3: tailscale0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1280 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 500
    link/none

rfkill also shows it’s not blocked

For the second one, I’m already using an LTS Kernel, and tried different ones (5.15 and 5.10).

Disabling power save as mentioned in the thread did not resolve the issue.

Now I have another theory… I use ExpressVPN which has a network lock feature (when disconnected from the VPN), and was connected to a bad public network with low reception that kept connecting/disconnecting and I suspect ExpressVPN might have stuck the network in a locked state…

[TomDalla]

Bingo. It was ExpressVPN that had locked the network in a bad state.

If anyone in the same situation… how I resolved was to disable network lock and try to connect (which obviously fails but then unlocks the network when doing so).
