2 wire 1000sw

Hi!
Kindly check if you are using the same 2wire power adapter that came originally with the whole package, also try plugging it in another power outlet, like the kitchen or bathroom, & see how long the power light stays on. Plug it straight in the wall socket. If power light keeps going on/off even if you have plugged it in another power outlet, maybe you need to restore this modem back to its default settings. That can be done by doing a hard reset on the modem, push the reset button (found between the ethernet & usb ports), but be sure you have a record of your username & password on your internet account.
