Signal boosters (amplifiers, or 'amps') usually cause more noise on the line which will result in disconnects. Also it will kill the upstream signal (out of spec). Amps on a cable modem are never a good idea. Think about it this way: an amplifier is basically "screaming" at the cable modem. You can't "listen" very well with someone "screaming" at you, can you?

Bottom Line: avoid any "booster" or "amplifier" devices on your modem's line.
