I added a new Motorola SurfBoard modem about 2 months ago. Everything was fine for about 6 weeks but now every once in awhile I while surfing the internet I get redirected to a page that appears to be the Comcast registration page. Sometimes the page has one box asking me for my Comcast account number and other times the page displays two boxes asking for my Comcast ID and password. I have scanned my pc for trojans and it appears clean. Could this be a phone web page tring to get my Comcat info? The address appears legit as it reads something to like http Comcast Netminder Agent Reg". Or is it a modem reg issue?

You have a bit of a connection quality issue which 'may' be causing the issue. Are there any excess/unneeded coax splitters in the line leading directly to the modem that can be eliminated ? Also try refreshing all connectors within your reach and insure that that are tight. It may still be a provisioning issue with which a phone call will be necessary. If you can't get that upstream power level down below 50dB a tech visit is indicated.
