Its the modems configuration page, click on the SIGNAL tab on the left.
If your Signal To Noise Ratio is higher than like 40db, you could have too many splitters, normal installation is one out and one inside, but you dont need more than that. If you do have more than that call your cable provider and see if they can get it down to 2 splitters or less. GL
I have the same cable modem as the thread starter and have never had any problems, my Signal To Noise Ratio is under 36. That motorola modem is a very good modem.
Also go into the LOGS tab and see what error messages you are getting, they could help in troubleshooting your reset problem when contacting your ISP.
