I live in Massachusetts and I get my broadband cable through Comcast .
It seems that my cable falls off only during part of the day ( early to
mid morning ) and is fine at other times . Comcast support says that it
seems like like a modem problem . Are modems tempermental ? Any help
appreciated . BV

I've been with Comcast (S. Calif) for about 3 years using the USR
"shark fin", and I've been using the Motorola 5120 for about 10 months
with not a single problem from either of them. What kind of modem do
you have and does it have clearance on all sides for convective cooling?
Tell us the modem, and someone here might be able to tell you how to
read its web page. In all likelyhood, though, the problem is not the modem.

What are your RF readings from the modem's status page ?

TVs are plain hot in back esp. up top where they vent. Try moving at
least 3 feet away from the TV, but it's probably not the TV unless
it's plasma.

If you're renting, I'd be looking to upgrade to a DOCSIS 2 modem -
your modem is older than many of the active poster's kids. :)

What did support say beyond "seems like"? Did they check anything or
was it just "the modem is the problem" without checking, or with
little explanation?

Is this a house, condo, apartment?

I can't speak to Comcast, but you will find an answer. It's taking me
awhile to accept a dumb/passive device could go bad.
