Hello!
Here is more details:
1.Modem config page is disabled so no info is available.
2. TV is a regular analog TV-set (2 year old 27" Sony) located about
8-10 feet from the modem. modem located about 2 feet from the
wall/outlet
3. There is only one signal split (and splitter) on the cable line in
my bedroom 2, the main line splits into 2 lines, one goes to the TVset
the other to the modem.
Now here is an interesting thing (I wasn't clear enough in my first
post). What makes me think it's a signal strength issue is that when I
use either regular (for $5, 1GHz, RCA, no other info ) or monster
(already returned) splitter, the modem is not working even with TV
cable unplugged. It looks like (to me) that the signal after the split
is too weak. I mean too weak for the modem since TV always works fine.
So I bought an amplified splitter

which I am also thinking about returning) and there is an improvement!
Modem works fine with the splitter on the line (which I interpret as a
stronger, amplified signal ) but under one condition: TV cable has to
be unplugged. This suggests me that with TV cable on signal gets weaker
(is that true?) and modem stops working.
My another choice would be a signal booster with very good reviews:
http://www.circuitcity.com/ssm/Motorola-Signal-Booster-484095-001-00/sem/rpsm/oid/44964/rpem/ccd/productDetail.do
But I am getting a kind of tired of driving back and forth and
returning items one by one. And I am not completely sure if it's only
the signal strength what causes this weird behavior.
Thank you for your reply, problem still not solved!
