You're correct... or, in my case, I have the higher-speed tier, and there
wasn't much of a question: they gave me a modem.
I had a router from them previously. Like someone else said here, I really
don't want Comcast inside my network at all. I didn't want them to have
control over my WAP, either, and they didn't offer 802.11n at that time. At
one point, IIRC, the router/WAP package ("home networking package"?) specified
the ability to have 5 home devices. I haven't had any issues with my setup
with them. I don't see any advantage to a technical user having an
"all-in-one" modem/router/WAP.
I tried at first to even purchase my own DOCSIS 3.0 modem so I could even
control that part of the equation. The Motorola SB6120 wasn't available at the
time to purchase, but I see Amazon has it for $81. And there may even be
people on this list who have an old DOCSIS modem in their basement they would
be happy to part with - I gave mine away last year.
Comcast is actually doing some fairly good things these days, from my
perspective. They are working on IPv6 rollout; they have 6to4 access and 6RD
(I don't think my IOS-based Cisco supports 6RD, so I am using a tunnel from
he.net for the moment) and they are trying to help with things like botnet
detection. One of their guys gave a good presentation at NANOG recently on
their plans... for what I pay, I think the service is pretty good.
Some months I might get a bit closer to the 250GB transfer limit than I'd like,
but they even introduced their own traffic monitor so anyone can see what their
usage is (I'd written my own before this). But like any other company in
technology, there are certain questions I just know I'd be wasting my time
asking (like a colleague who called their "business class" sales guy and asked
about BGP...).
Happy to help with any specifics or pointers offline if your friend needs the
help.
