Router connection is sporadically disconnecting on LAN1 for FB6660. I couldn't find a reason behind it. It is a new router and also a new generation, what avm is doing? Looks like is an old issue. I have also installed the latest lab version of the firmware, without any change in behavior. Reading this thread, I have changed on different LAN port. But soon I will be in need of the 2,5G port. I hope AVM will fix this soon.
