Cable signal boosters....

[Sphexi]

Get the 15-2505 Bi-directional 1-to-1 and put it as the first thing after your cable comes into your house. It'll boost the signal enough to fix your problems, and won't interfere with digital cable boxes or your cable modem. It's $31 at RS, works perfectly fine.
