I have comcast internet with a wireless router. I am having a terrible time browsing the internet. When I try to go to a site it will say different messages depending on the browser but they all basically mean the site cannot be found. I have to hit refresh or try again up to 20 times and then finally the page will load. Comcast says that according to their system they show a full connection coming into the house. My email never goes down, my wireless connection to Xbox Live never disconnects, and when I listen to Sirius online it never interrupts so it does seem that the connection from Comcast is working. I have rebooted everything including the modem and router several times over the last few weeks. I have tried my laptop and PC with Chrome, IE, and Firefox on each one and hard wired directly to the modem and it's the same problem mo matter what.
