[Solved] Wifi connection drops very frequently

ethem · 2021-05-31 19:42:46

Hello! I installed Arch Linux a few days ago. My wireless connection drops very frequently. I tried to turn off power saving mode and looks like succeed. But the problem is still exist, nothing changed. I used manjaro, debian, ubuntu etc on the same laptop but I never had similar issue. What should I do next?

dmesg

wlan0: deauthenticating from <mac-address> by local choice (Reason: 3=DEAUTH_LEAVING)

iw dev wlan0 get power_save

Power save: off

systemctl status NetworkManager

I'm using NetworkManager, wifi card is Intel, driver is iwlwifi. I can add outputs if requested. Thanks in advance!

Start by stop/disabling dhcpcd and iwd if you want to use networkmanager.
Then report back w/ an updated journal if the issue remains.

I restarted both, and unfortunately issue remains
full output of journal (did a reboot): https://gist.github.com/ethmtrgt/c82300 … cbec70b1a6

Who said anything about restarting? They compete w/ networkmanager and each other and you end up with the tree stooges syndrome

Ah sorry for misunderstanding. Wlan0 disappears if i stop iwd.

seth · 2021-05-31 21:22:21

sudo systemctl disable iwd
sudo systemctl disable dhcpcd
sudo reboot

Thanks a lot seth, I had lots of disconnection events too and it seems it was caused by the iwd service.
You solved my problem too

Note for other with similar problem that iwd is a dependency of NetworkManager and that you shouldn't uninstall it if you use NetworkManager but disabling the service is okay.

Thanks,

BT
