Wrong Device Shown in 'Device Info'

... When I go to the Device Info page (https://www.xfinity.com/support/devices/#auth), it lists my current device as the ARRIS SBG1000 (which is incorrect and incompatible) instead of the ARRIS SBG10 (which is the device I own). ... How do I fix this?

It's been broken for over two years, so if it's ever fixed, I doubt if it will be anytime soon. See https://forums.xfinity.com/conversations/your-home-network/re-routermodem-keeps-rebooting-arris-sbg10/602db073c5375f08cd2e9710?commentId=602db085c5375f08cd315b6d.

... Do you think I should go ahead and just purchase a DOCSIS 3.1 modem ...

Connections problems are most often caused by the link between user devices and the modem/router gateway, or the link between it and Comcast, rather than the device itself.

Are you connecting via Wifi or Ethernet? If Wifi, it's best to switch to an Ethernet cable connection if possible for testing. That would allow you to determine whether the problem is the Wifi signal or the link between your gateway and Comcast's network. Network connection problems that affect both Ethernet and Wifi devices 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 Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed the following information from your gateway (from http://192.168.100.1):

• downstream: power levels, SNR, and error counts
• upstream: power levels
• event log, if available (Be sure to remove or blot out any MAC addresses. Forum security processing considers them "personal information" and may prevent the event log from posting if these are present.)

If you can't find the problem or you'd rather have Comcast take care of it, 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 ($70-$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.
