G3100 router dropping internet connection

[Maryeo]

My wife called that the Internet was out. When I returned home around 6 pm I reset the router and the problem resolved. I copied some of the log information showing the problem occurred around 9 am this morning. The first dnsmasq err line is repeated continuously up to the router restarting.

There is a repeated warning of a possible DNS-rebind attack detected. 192.168.1.89 is the ip address of our Synology NAS.

Anyway, I am interested in whether you can shed any light on what happened. The router (G3100) was sitting with its regular white circle and was supporting wifi connections but no internet connection.

They are having major DNS issues. I am experiencing the same problem and it appears many others on the forum are as well. Unable to resolve certain sites intermittently while others work fully.

Same for me too, I had to reset it also.
