Ha, I wish.
Comcrap was giving me about -5 dBmV a few years ago. I needed a drop amp just so I could do some splitting. The Motorola amp I wound up using supports a low loss return path and I had no problems using my cable modem with it.
The sad thing is the bozo management at Comcrap sends their installers out with very very little equipment. I had signal strength problems before dropping them years previously, so when I had my Comcrap install I asked the guy to check the signal level and/or quality. Nope, no can do. Hasn't got the equipment, and as long as my 1 TV in the garage had a viewable picture the guy was done!
Contrast with my recent FiOS install. They guy knew WTF he was doing. He even had some sort of hand-held gadget that checked the signal at multiple freqencies at each outlet in my house. No wonder Comcrap gets voted the worst company in America.
