Hi! After long years I’m back to linux and specifically, I’m using the latest Manjaro with KDE.
All is great so far, except networking is iffy at some times.
The problem is IPV6 drops and stops working, all requests are then routed through IPV4 which still works. It will start working again if I reconnect from NetworkManager applet.
Providing some logs below.
By looking at NetworkManager and avahi I see that when this happens, it’s because avahi replaces my global ipv6 with link-local. Is it possible to know why and to configure just to maybe try getting a new one if lease expires?
