Wifi disconnection while updating/installing packages in KDE Plasma

Hi, newbie here! I recently freshly installed EndeavourOS with KDE Plasma. I’ve been experiencing wifi dropouts or even disconnections while using pacman -Syyu and updating mirrors, either by using Reflector or the eos ranking mirror command. My internet connection seems to be fine as there is no connection problem in my other devices.

After the first one, I tried another fresh install, then update the system/mirrors in the live session (xfce) and there was no problem, everything went normal.

This is my inxi -na and iwconfig output:

Network:

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:61   Missed beacon:0

Interestingly, the wlan0 state from the inxi output goes from up to down (matching the connection dropouts).
This is what I’ve already tried but with no success:

  • the modprob option nohwcrypt=1 from arch wiki
  • using LTS kernel
  • disabling IPv6 as mentioned in solutions from a few years ago or so. Apparently a problem with kde wallet.

Thanks in advance!

Have you tried disabling this? Not an expert just having a guess

How do you know? Did you also try?

btcoex_enable=1

Possibly also add

blink=1
