ot: do modems die?

[eddief]

Have had Comcast installed for a few years. That is triple play with phone, net, and TV. I was renting my modem for a long time and then decided to buy my own instead of rent. Think I paid upward toward $300 for the modem. Yesterday when I woke up the modem seemed dead. No lights blinking at all.

Called Comcast and they tried to troubleshoot over the phone and reboot the modem from their office. No luck. Sent out a live tech and he tested everything and thought my modem was dead. So now I am renting their modem again .

Why am is suspicious that Comcast could kill my modem if they wanted to? If they can re set it over the line, could they just as easily kill it?

Regardless the uptime over the years has been great and their service yesterday was exemplary.
