What could this be? I swapped the whole router. Still seems like we're having issues. Before the outage, the interface counters were clear. After the router came back up I had whole bunch of CRC errors, interface resets, unknown protocol drops.
When I called ISP they always tell me that there is nothing causing this on their end. I am starting to think that it might be an issue between my router and the circuit box on the wall. I swapped the cable but still nothing. ISP is constantly blaming that its a config issue on the router. Any ideas? I have a very simple config. VPN tunnel, NAT, and thats all
