Might try this as well, Re-load the v.7 FW or might try loading FW that was available last year and see if the reset still happens. You can emulate a power outage by pulling the power cord for say 15 seconds then back ON.
Seen others post regarding factory reset after power loss. I saw this early one with mine but have not since.

Lots of criticals that your ISP needs to look into.
What FW version is currently loaded?
Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

Thanks for the reply. Im not sure what criticals are but by the time stamp the modem has already reset itself and is trying to reconnect to the internet and is failing because well it factory reset itself and has to be set up. again not knowing much about modem and routers, even if there was a problem with my ISP, why would it still factory reset after i unplug it or reboot it or if the power goes out? are you saying the ISP is responsible for that?
FW: V.2.1.3.7
when i log into the modem via firefox there is a message saying a new router firmware upgrade is available. i click that and it say No New Firmware Version Available.
The coax cable comes directly from the street straight to the modem, one cable, no splitters. its whatever cable the cable company ran.
I NEED to be sure its the ISP before having them check anything because if they find no problems then they charge me $500. i had to fight this before so i already know.
