Wifi and Ethernet Randomly Disconnect after replacing router

Hi everyone!

I’m posting here because, as said in the title I’m facing random disconnection problems (every 5 seconds to 1 minute). They are simply displayed with the basic disconnected icon.

The weirdest thing about all of it, is that this doesn’t happens when I try with my smartphone’s Wifi, and also doesn’t happens when I connect from the same machine on Windows.

When it occurs, journalctl -f -t NetworkManager displays these 2 errors:

<warn> [1622073518.2308] device (wlp2s0): failure to start DHCPv6: failed to start client: Adresse déjà utilisée (means address already used)

<warn> [1622073518.2353] device (wlp2s0): Activation: failed for connection [wps name]

Thank you very much in advance for your help guys!

Disable IPv6 and also mac address randomization.

Thank you very much, I’m going to try this in a little while.

Well I finally did a bios update (probably a bad idea), and this made me have to start on a clean install. Anyway thank you very much for your help!
