My husband & i also have TWC & had packet loss via routing through hubs at Cogent Co & iweb. I contacted Cogent Co & this was their reply...

Dear Cogent Customer,

The latency and/or packet loss that you are experiencing to this destination is due to occasional high traffic with [Time Warner]. We have repeatedly requested augments to these congestion points and hope [Time Warner] will comply soon. While this has been escalated internally to the CEO level, we encourage you to also contact [Time Warner] customer support with your concerns and complaints. Their delay is a major impediment to internet traffic overall and contrary to net neutrality requirements. Our peering engineers will continue to address this on a daily basis until resolved.

Thank You,

Cogent Communications

Not sure if this is legit or not. We have called TWC & they say it's not their issue. No one will take responsibility it seems.
