As others have said, the best thing would be to run a separate cable for
the modem, but you might be able to get away with your current setup by
using directional taps instead of simple splitters. A splitter sends
half the incomming signal to each outlet, so the first jack in the chain
gets 1/2 the original signal and sends 1/2 along the chain, the next
jack in line gets 1/4 of the original signal, the jack after that 1/8,
then 1/16, etc. Taps, while harder to find, split the signal unevenly
so that most of the signal is sent along the chain with only a small
amount being sent to the jack, which keeps the signal level from
diminishing so quickly as you go along the chain.
If you still need an amplifier, you must get one that has a return path
(bidirectional). Simple unidirectional amplifiers block the cable
modem's upstream transmissions, which keeps it from working.
I think we need to change the rules. -- Calvin
