Wireless interface keeps disconnecting and reconnecting.

Hi!

After a pacman -Syu my wireless interface won't stop dissapearing and reappearing. I cannot connect to wifi.

I'm using wpa_supplicant and NetworkManager and they've worked just fine up until this update.

• journalctl -b -g wlo1:

• uname -a

  Linux sarahkitty 5.4.2-arch1-1 #1 SMP PREEMPT Thu, 05 Dec 2019 12:29:40 +0000 x86_64 GNU/Linux

• Package versions

  iw 5.3-2
  networkmanager 1.20.8-1
  wpa_supplicant 2:2.9-2

It seems to repeat this error over and over again, each time increasing the index of the wireless interface. I've already tried downgrading:

• The Linux kernel / headers / firmware

• NetworkManager

• wpa_supplicant

What can I do?

Re: Wireless interface keeps disconnecting and reconnecting.

https://bugs.archlinux.org/task/64703

Edit: I was under the impression that downgrading the Kernel would work around this.

Re: Wireless interface keeps disconnecting and reconnecting.

To rule out another cause what is the output of

systemctl list-unit-files --state=enabled

Re: Wireless interface keeps disconnecting and reconnecting.

Hi, sorry for the late reply-- I read the bug report, and I was downgrading to a still broken version. Downgrading to 5.3 fixed it.

Thank you for the help!
