Thanks for the feedback. I couldve sworn the Netgear rep I spoke with said the power shoudl be .5 dBmV...but maybe Im not remembering correctly. I shouldve put in my original post, the first thing I did when getting connection issues was have the ISP come out and check out the lines. Everything according to them is good. They checked the signal to the modem and there are no splitters at all in the house. I didnt ask them specifically if they provisioned the modem correctly so I can check on that. I also can check to see if RG6 is being used. Thanks for the advice...much appreciated. Ill check out the links you posted as well.
