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."

It's in a wholly-different subnet (un;less you've changed the default to 192.168.1.0) and those connections get an IP out of a different pool (50.n.n.n v4 block here) than the pool serving your gateway (76.n.n.n).

      How can it when it has to do all that for v4 as well? I found a reference to 80% of sites being v4 only (2009, so old, but not that old). So 80% of your resources are spend on v4, and you have to have a separate process for v6. I've looked and I've never seen anything anywhere, other than you, that claimed dual-stack was less resource intensive for CPE/end-user than v4 only. Everything I've seen indicated that dual-stack would have been used more extensively if it wasn't more resource intensive than v4 only.

      My preference would be to do v6 only (customer and core), with NAT64 for the 20%of the Internet that's not v6, but that'll work for getting to almost everything on the planet but Skype.

      There's cost in buying and managing v4 addresses, and dual-stack doesn't fix that. So v4 only is "cheaper" and easier than dual stack.

      As soon as MS fixes Skype, I'll be pushing for v6 only, but if they don't put out a new version this month, I'll be forced to run v4 only and maybe eventually dual-stack for a transition period. But dual-stack indefinitely for no reason than a religious affiliation with v6 is stupid and wasteful.

      I blame Skype. They are the *only* roadblock to v6 at this point. No other popular protocol/app is hard-wired to v4-only.

      No, I'm not going to punish my customers to appease your religion of v6. When v6 compatibility hurts the customer, the ISPs should reject it.

      You know where this logic is headed, right? It won't be long before you won't be able to buy a bunch of v4 addresses for them. Or maybe you will, but they'll be expensive enough to seriously impact your bottom line. Will an extra $5/mo on each customer's bill be enough to count as an inferior experience for them? What about $10/mo? $20/mo? (Not just your bill, mind. Their Netflix bill too, or anybody else they pay for any services that need a server to run. Or maybe the service is free, but shut down because servers are too expensive due to the IP cost.)

It also assumes you are giving out multiple public v6 addresses to end users, when I've not seen that in practice.

    Which you can do if you buy your own.

    Those all-in-ones are trouble in two big ways:

    1) Failure due to heat. When you start trying to jam all the components in to one box, it gets hot. They can't go for a big case or fans or something like that, because consumers won't like it. So they run hot, and tend to fail sooner. No guarantees of course, but my informal observation shows that separate units work for longer.

    2) Limited and expensive upgrade path. If one component of the system is outdated and you want to replace it, well you get to toss the whole thing and buy a new unit... assuming you can even get one. Like on Cox, all their all-in-ones are still only N wireless, no AC available. If you have separate units, you can upgrade them as you need/want to.

    I find it much nicer to pay more up front, and have the better setup and options. Personally I have a Cisco cable modem, Edgerouter Lite router, and Netgear R7000 wifi bridge (it could act as a router, but is set not to). They work nice and stable, never needing reboots, I have the latest WiFi technology, and I can upgrade any piece as I wish. As a practical matter the WiFi will probably get upgraded first, in a few years, the cable modem next, whenever they start offering speeds in excess of what an 8x modem can handle, and the router not for a very long time, since it can handle a gig of throughput.

    So while my up front costs were high, there's no monthly charge, I have excellent performance and stability, and support for the latest stuff.
