So my cable modem has taken to randomly shutting off. There is no reason that I can see for it to happen. When it happens all the lights on the modem die except for the power light. The windows event log records an event of ... Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address **MAC ADDRESS**. The following error occurred: The operation was canceled by the user. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server. The thing about that is I DIDN'T CANCEL ANYTHING! Sometimes it happens while I'm in bed, sometimes it happens while downloading and sometimes in the middle of a WoW raid, its happened 14 times today (5 since I've been typing this). So there isn't anything obvious thats causing it, and I know its not my computer (what with the lights shutting off and all). I've called the cable company, they have replaced the modem, the cabling, the ac adapter, basically everything. I've changed my plan (they suggested I MIGHT be downloading too much, course they don't know how much is too much) and it still happens. Are there any other ideas out there?
