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.

    All of the above have been done. I was on the phone with my ISP multiple times trying to troubleshoot this device. Once again, I cannot access the unit so I can't post a status page of any sort. The connection works fine using my older Netgear modem/router, so it's not my ISP. Factory reset does nothing. I tried resetting, unplugging it for up to 10 minutes, used different ethernet cables. On my browser i have tried routerlogin.com, routerlogin.net, 192.168.0.1, 192.168.1.1 but I cannot connect the the router interface at all. I have owned many Netgear routers so I'm familiar with troubleshooting and so far nothing I know is working.
