After a while in game my ethernet connection turns off

Hi, Every time i try to game in arch after a while my wired connection turns off, i can just connect to it again but in game i need to close and open it again. This happens with the NM + iwd setup, NM only and iwd + systemd_networkd. This is the "find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f "output:

Please use "code" tags for the find output.

Why using iwd (a wireless daemon)  with a wired/Ethernet connection?

Sorry for the missing tag, and I was using iwd only for wireless connection with nm or networkd for the wired connection. And the wired connection disconnects and connects again outside games too.

What does NetworkManager say when the connection is dropped?

journalctl -b | grep NetworkManager

There is another device in your network claiming the address "192.168.1.106" - with a MAC address belonging to "LiteOn Technology".

Resolve this IP conflict.

Thank you. I disabled my dhcp and made a static ip configuration and it solved the issues with my wired connection.

Re: After a while in game my ethernet connection turns off

Doing that on other system is what caused this in the first place. You need to figure out how you want your overall network set up. Don't run a DHCP server that's handing out the same IPs as you have static for a start.
