TWC supplied me an Arris DG1670a when I started with them 60 days ago, and frankly it works well. I prefer the configuration it has with 2.4GHz wireless, 5 GHz wireless, and four Ethernet ports. Due to my equipment setup I at home, my preference it to have an onboard Ethernet router for the gateway.

This device has been bulletproof and the wireless signals are carrying far better than the Netgear gateway I was using when on DSL. I'm on a 50M/5M plan at TWC, but actually get 8% faster speedtests. Yet for the $8/month I'd like to determine what my payback period is if I buy a new gateway. Yet I want a device that has the same port configurations. I don't see an Arris device in TWC's official BYO replacement links that match the DG1670a capabilities. Thoughts?
