Two bedroom apartment, both bedrooms with TV outlets. Bedroom 1 has an analog TV enabled outlet, bedroom 2 runs a RoadRunner cable modem. This works fine, but I'd like to have a tiny TV-set hooked up in bedroom 2 too. There is TV signal coming from the outlet in bedroom 2, but surprisingly TV and cable modem don't want to work together at the same time (splitting the signal). TV works all the time but cable modem works only when "to-TV" cable is unplugged.
Yes, I bought a good splitter (2GHz monster cable for $25) - did not help. Then I tried an amplified 4-out splitter from RadioShack ($50, HDTV & high-Speed ready, gain is 8dB on each output) and still the same. When only modem is connected it works fine. When I plug in the TV cable to the splitter the modem becomes dead after 10-15 seconds and is not able to reinitiate the connection until I unplug the TV cable.
Any ideas what's wrong? Is it a signal strength issue or maybe I am missing something? My Internet transfers are pretty good up to 4Mbs.
