Hello

since almost one week, when I power on the laptop, I experience for almost 15 minutes continuous disconnections from the AP.
Than the connection get stable and it does not disconnects anymore.
I got the same problem with NetworkManager and IWD
here is a log:

Please use [code][/code] tags. Edit your post in this regard.

Try

sudo iwconfig wlan0 power off

if that doesn't help, please post a complete system journal for a boot covering the disconnects:

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

thanks a lot for your answer
but if I power off wlan0, how should I connect to the AP?

I'm not sure who typed the above, but it certainly wasn't my brain… sorry

sudo iw dev wlan0 set power_save off

Edit: fuck
