Posting in the Forums does not mean you are talking to anyone in Comcast that can fix your problems. We are customers just like you, that volunteer time here trying to help fellow customers.
You need to call 1-800 comcast and have a Tech come out. OR- You can post the problems you are having in detail here, and someone will try to help you- if it can be done without a Tech coming to your home. But you need to give some specific details for anyone to help in the Forums.
