im having an issue with my cable modem. All the lights on the modem stay on, but all of a sudden it loses internet connection, i ping a website, and the request times out. I check to see if im keeping my ip address in the network connections, and the ip address is staying the same. ive tried calling comcast, which says everything on there end is good. ive replaced the coax cable going to the modem, ive unhooked the network cable and hooked up the modem through the usb. ive cut off windows firewall. im all out of ideas here. whats making me think is that the lights are all staying on, like nothing is wrong. i cut the computer on this morning, soon as i got into windows and tried to load a webpage, samething, then all of a sudden it will work, then a few minutes later, its out. internet games is impossible like this. im leaning towards it being a bad modem. i have a motorola surfboard 5100 modem. what do you guys think? thanks for all the help in advance.

Your modem is probably crapping out when transmitting. I would contact comcast for a replacement. You will probably have to pay for it.

I don't think it would make a difference. I usually stick with Motorola.
