I'm CenturyLink VDSL customer with bonded-pair service.
In my opinion, Century doesn't have router with features I need (NAT loopback, advanced port forwarding, 5GHz WiFi...)
So, I was using Technicolor C2000T as a modem, in a bridge mode plus T-Mobile router (which is re-branded ASUS RT-AC68U).
Router configured to connect via PPPoE.
And I noticed, that I often (few times per hour) losing my Internet connection for brief periods (5-15 seconds). While that happening my router shows Internet status as DISCONNECTED.
While troubleshooting I removed the router and enabled build-in router of the Technicolor C2000T and now it much better.
Here is link to Before (T-Mobile router) / After (Technicolor C2000T) graph as drawn by PingPlotter:

I was thinking, that it is only modem responsible for Internet connection, and router just handles my LAN. Obviously I was wrong. But I do not understand - why is it? How router can contribute to WAN disconnects?
Should I get new router or can I somehow configure it to be more stable?
