Query: signal booster

I have 8 tv's in my home and internet. Two of the tv's are hd. Needless to say we had a signal problem. But after I installed the booster AFTER the internet modem. It all works great. I had the modem on the boosted side but it didn't run properly.All in all it's well worth the price.
