ICMPv6 RA: ndisc_router_discovery() failed to add default route.

[Sum_Guy]

I see another thread on this topic, but just checking to see if the solution in that one (bad copper connection at the street) applies across the board: https://forum.telus.com/t5/Internet-Home-Phone/Internet-Dropping-Out-Daily/m-p/115403.

Telus has said no issues with my line.

I have all but one or two of my devices connected to a modem behind the T3200M. I've been having problems with one of my devices losing its internet connection, so I decided to connect it directly to the Telus modem/router. I'm still having problems.

I factory reset the Telus modem/router to see if it would clear up the following errors.

Just curious, are they anything to be worried about or can I ignore them?  Could they be causing a device to drop its connection?

I got the same issue as you. My connection keeps dropping out during the day. I also asked to replace the modem/router but I didn't help at all. I wasted my time to call them customer service many times since it didn't work.
