I am having problems with my Comcast internet connection. When connecting my computer to the Comcast modem I get an error message saying “limited or no connectivity”. If I reset the modem (unplug the modem, wait 10 seconds and plug back in) I am able to get an internet connection. However, when I unplug my computer and plug the internet connection into a different computer I get the error message again “limited or no connectivity”. If I reset the modem again I am able to get a connection. What can I do to avoid having to reset the modem every time I change the computer connected to the Comcast internet connection.
