[Solved] wifi not working after update

NetworkManager does not scan for wifi and does not connect to saved network

$ nmcli radio wifi on 
$ nmcli device wifi list 
IN-USE  BSSID  SSID  MODE  CHAN  RATE  SIGNAL  BARS  SECURITY

$ ip link show
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DORMANT group default qlen 1000
    link/ether 7e:f2:1f:45:7c:78 brd ff:ff:ff:ff:ff:ff permaddr 50:c2:e8:0c:71:39

$ inxi -N                                             
Network:
  Device-1: MEDIATEK MT7921K Wi-Fi 6E 80MHz driver: mt7921e
  Device-2: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
    driver: r8169

Tried iwd as well, not scanning either.
To be clear, it was all working out of the box, all I can imagine doing to break it is update.

Re: [Solved] wifi not working after update

Does the LTS kernel still work?

Please post a complete system journal

sudo journalctl -b | curl -F 'file=@-' 0x0.st

and the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Ceterum censeo: Is there a parallel windows installation?

linux-lts does not have the drivers

Re: [Solved] wifi not working after update

There're no issues logged (particualrily no parallel runs of iwd and wpa_supplicant)
On a random guess, try to disable https://wiki.archlinux.org/title/Networ … domization

Also

Ceterum censeo: Is there a parallel windows installation?

It does:

No I don't and disabling randomize mac doesn't work

It does

It does not load though

I reinstalled the whole system by the way, still doesn't work.
Silly to me because apparently it isn't working on archinst iso either

Re: [Solved] wifi not working after update

Did you reboot and check the journal to make sure the MAC was no longer altered?

What do you mean "it doesn't load"?
Do you have a journal for the LTS kernel?

Silly to me because apparently it isn't working on archinst iso either

To be clear, it was all working out of the box, all I can imagine doing to break it is update.

Are we sure there're any SSIDs in range and did you maybe just got a lease using the Realtek RTL8111/8168/8411 ?

Re: [Solved] wifi not working after update

nmcli m would have these output

Networkmanager is now in the 'connecting' state

and as for my android USB tethering

Re: [Solved] wifi not working after update

I'm going to tell a bit of a story.
My laptop has a default RGB colour of blue, and I have an automated script to make it purple, because every time my laptop shut Down for a while it switches it back.
I was working on my network problem for a day or so, and I realised that I haven't see a blue keyboard for quite a while. Since I reinstalled the system, that shouldn't be right.
I shut it down and unplug the power adapter, wait for about 30 seconds and boot it up. Here I am, blue keyboard backlight and working wifi.

I am sorry for Seth trying to help me with my problem, we are both wasting our time apparently.
