Replace faulty modem
Two to three times a day the cable modem (XB7, rented) goes down. I've checked and everything inside the local network works fine during the outages and I cannot log into the modem during these times. I've tried both rebooting and factory reset but neither works.
What do I need to do to get the modem replaced?

Chances are the XB7 is OK, and the problem is the link between your gateway and Comcast's network. Network connection problems are often due to poor coax connections or damaged coax cable, usually in or near your home. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power.
If you want to troubleshoot this yourself, please see Connection Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your modem or gateway (from http://10.0.0.1):

If you can't find the problem or you'd rather have Comcast take care of it and an employee does not respond to your message here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit (approx $100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.

As an FWIW / FYI, with many models of modems, the user interface pages can not be accessed if the modem isn't online / synchronized with the ISP's system. Perhaps that's the case for you.

Please also post the channel ID or number, frequency, and modulation type for each channel. It isn't possible to interpret the stats posted without this information.

Thank you. The signal stats look OK except for #48 (850MHz) where the power level is borderline (too low). The error counts on that channel are a bit high as well, along with some of the other channels. If you can't correct these using the troubleshooting tips it would be best to have Comcast send out a tech to find and correct the problem.
