I had to put the modem in my room instead of where it used to be connected at and I am wondering if I should get some cable from Comcast and run a new line for it?
I don't know what the levels on this new Modem are supposed to be.
Any links on where i can learn more about this style off connection and teh proper levels would be greatly appreciated.

Here is a decent guide to look through about signals http://www.speedguide.net/read_articles.php?id=1197

Thanks. It looks like I am about perfect. I am wondering though why I show up as DOCSIS 2.0 upstream when the information I read about my speed Tier says I am supposed to be DOCSIS 3.0

Well it could be that modem is only docsis 2 or maybe the isp is still using version 2 instead of 3 that's what the modem is reading.
