Wifi Disconnect After A Short Time

Hello everyone,

I use netctl to connect to the wifi and every like 5 minutes I have to run

sudo netctl restart <templatename>

and it stays connected for the next minutes. I am not sure if it only disconnects when I am reading (and not actively using the wifi) or if it disconnects even if I am using the wifi. Maybe it has something to do with power saving...

The

iw dev wlp3s0 get power_save

returns off, thats what I already tried. And I tried instead of netctl connman. But the same issue.

Thanks in advance and please give me the command I've to enter in the console if you need more information.

Edit: When I rund the command 'dmsg' I get the following:

wlp3s0: deauthenticating from d4:d1:84:4a:fa:15 by local choice (Reason: 3=DEAUTH_LEAVING)

But I already disabled the power safing feature mentioned here and in the BIOS settings I cant find "PCI-Express power management".

Re: Wifi Disconnect After A Short Time

Could you post the output of ls -l /etc/systemd/system   ?
I want to ensure you have only enabled one service that will try to control the network connection.

Re: Wifi Disconnect After A Short Time

The output of 'ls -l /etc/systemd/system' is:

total 32
drwxr-xr-x 5 root root 4096 Aug  7 15:31 .
drwxr-xr-x 5 root root 4096 Aug  5 03:57 ..

-rw-r--r-- 1 root root  654 Aug  1 07:48 systemd-fsck@.service

I just saw, that after a reboot the 'iw dev wlp3s0 get power_save' says that it is on....

Maybe my udev rule isn't correct:

ACTION=="add", SUBSYSTEM=="net", KERNEL=="wlan*", RUN+="/usr/bin/iw dev %k set power_save off"

But even if I disable the power safing in the current session I get the disconnects every minute.

Re: Wifi Disconnect After A Short Time

That list of services looks fine.
I don't have your hardware, so I cannot help beyond the generic stuff.  I think you are on the right track with the power save.

Does it behave this way on other access points?
How far are you from your access point?
I know it is not a running service, but do you have NetworkManager installed and is it possible that something (like a desktop environment) is starting it?

Re: Wifi Disconnect After A Short Time

Does it behave this way on other access points?

I installed arch 2 days ago. Haven't had the change to access somewhere else.

How far are you from your access point?

Like 5 meters trough the wall. I can connect, and when I am connected the speed is super fast. It just disconnects me after some minutes (2-3).

I know it is not a running service, but do you have NetworkManager installed and is it possible that something (like a desktop environment) is starting it?

I tried wicd, networkmanager, connman and now I am back to netctl. I should have removed them correctly (disabled them & stopped them with systemctl and deinstalled with pacman).

And the desktop environment is i3wm and should not load anything network related.

Thanks for trying to help me. That means a lot!

Edit: Okay, I am a little bit confused. When I

killall wpa_supplicant

the connection is back... Thats strange. And I tried to stop and disable wpa_supplicant. But that doesnt care wpa_supplicant.

Any ideas?
