Comcast Triple Play and Router? Edward 06-30-07

My brother is going to get the Comcast triple play, phone internet and
TV.
My questions is, does he have to use THEIR cable modem, or can I get
him one of those Linksys cable modem/router combos?
Can I use a router if there is going to be a special Comcast cable
modem?

You need a modem that supports VOIP and I would keep the modem separate from
the router (you'll thank me later).

So get an Comcast approved VOIP modem (or rent theirs [unless it's free]) and
buy a spearate wireless G router with integrated 4-port switch to handle your
PCs.

The TVs are handled by splitting the BB cable (usually at home entry point) and
the modem will be on the first leg of the splitter and handle your other
needs.

Router technology is about ot go to 'N', we are currently at 'G'. 'N'
reaches out and can touch your neighbors or backyard easily and is
also faster. It is currently called "pre N" because the standard has
not been written and accepted by all the companies involved yet. When
it does come out, your modem/router combo will be outdated and you
will be stuck buying a new setup. Buy them seperate!

I'm not entirely certain how their digital phone service works, but I
believe it uses a separate connection that is then tied into your home's
phone lines. It is not traditional VOIP like Vonage, but something
unique that is specifcially designed for cable. Your TV and Internet,
along with the phone adapter, just split the incoming cable. In other
words, the Internet is only for your computers and you can treat it as
normal.

The main potential issue could be a weak cable signal due to the 3-way
split you may end up with.

I think they use an adapter to the existing cable modem, so I'm probably
wrong about needing a VOIP modem. They do use VOIP over a private network
I believe, but the adapter allows them to connect up to a regular cable
modem. I think they have plans for a combined modem/adapter.

I'd try to go with a standard Motorola mode and Linksys/Netgear G router
until N is solid. Then you should only have to connect their adapter to
the modem to add phone service - TTBOMK.
