I took my old modem to the local Comcast location and traded it for another one because it was not working properly. I set up the new one and have not been able to get past the welcome screen (download software screen). I have downloaded the software and tried reinstalling it probably 10 or 12 times in the last 72 hrs and every time I complete it successfully I can't get any other webpage besides the welcome screen. I have been calling Comcast's 1 800 number for 3 days, estimating a total of over 100 calls and I have not been able to talk to a single person!!! Is anyone there?!?
I turned off my computer and unplugged my modem for a few minutes and booted back up. I was able to make it back here almost long enough to submit my reply. It went to a page not found screen. This is my second attempt. I called the different phone number on my cable bill but it took me to the same automated response with no hint of a person. It eventually just hangs up on you. I expect to be returned to the welcome screen at any moment. If I disappear, that's what has happened.
..I had this happen to me the other day after replacing my modem..try this,...(worked for me)...first...I'm assuming you have a router...pull the power from the router....with no power going to the router, pull the power from the cable modem...wait a few minutes....power up the cable modem...after a few minutes when the modem has completely powered up and went to all green...plug in your router...hopefully this will work....my 4th tech call told me this and it worked. good luck..

Had that issue when I swapped out my modem last week. Check your IE settings and make sure that it's not trying to use a proxy. Apparently when I tried to run that same software, it had enabled a proxy server that was causing all kinds of issues.
