Connection drops out after a few minutes

hallofangels · 2021-08-20 00:48:03

My connection drops out after a few minutes, sometimes it comes back, sometimes it doesn't. This notably happens when I do anything stressful to it, like downloading games on steam or watching 4k video on youtube.

dmesg: http://ix.io/3wv1

sudo journalctl -fb after it happened a few times:

it also happens when i use usb tethering from my phone, so it's not a problem with my dongle i don't think, but just in case i'm using a TP-Link TL-WN722N

The dmesg only shows wlp0s20f0u8 disconnects, typical reason for the symptoms are concurrent network managing services.

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

which could be due to https://wiki.archlinux.org/title/Power_ … utosuspend
nb. that userspace power managers like TLP can and typically will override that at runtime, so you'd have to configure the behavior there or disable them for a test.

In doubt post the system journal ("sudo journalctl -b")
