The Hidden Cost of Your New Xfinity Router

An anonymous reader writes "The battle over Comcast's public WiFi network that is hosted on your cable modem continues. Comcast responded to Speedify's earlier power measurements by rushing them a new Cisco cable modem. The new modem proved to be more power hungry than the last, and also introduced some tricky IPv6 problems that caused major headaches for the team."

As someone who had the DPC3939

[Lothsahn]

The device has stability problems as well, as mentioned in the post. In normal (routed) mode, it worked fairly well, although I noticed odd lag spikes and other issues I didn't experience with the old modem. However, once you place the router into bridge mode (disabling all wifi features so I can use my modem direct), the router would reboot itself every 3-8 minutes.

I eventually, after talking to 20+ Comcast reps, got them to put a different modem back in. Even though my plan is 250d/30u, I'm only getting 30d/5u, because the modem won't provision with my plan. However, it works, so I'd rather have that than a laggy, rebooting faster plan.

I strongly recommend avoiding the DPC3939 until the problems are resolved. It lalso ooks to me like all of the problems are software related, not hardware--usually they can be avoided by changing configuration options, etc.

He said he switched to OTA, so he likely dropped a pricy cable TV plan at the same time he dropped them as his ISP, hence the savings. After the special deals as a new customer expire (i.e. 12 months into the 24-month contract), several of Comcast's TV plans exceed $150, so even if he was paying the same for Internet with DSL, he could be saving $150 simply by having dropped cable TV for OTA.
