In most "CABLE" ISP setups your ISP MODEM must be the first TAP, not a
splitter, a TAP - the TAP is specific because it can attenuate the
signal strength so that your ISP signal is not to "hot" for your Cable
Modem.
The TAP looks like a "T", but one side will have a attenuation drop
leg/value, the other side is just passed through from the source.
So, your Cable Modem needs to be the FIRST connection, from the TAP, and
you do not use Cable TV from/connected to the TAP side....
WORLD ------ TAP PASS THROUGH ----- SPLITTER ---- TV's
TAP ATTENUATION side ---- Cable Modem
