I use my own modem for Comcast Business. It's from Arris, model SB8200. I used to login to it by using 10.1.10.1. This and 10.0.0.1 does not work anymore. I can login to Arris through 192.168.100.1. But this is not Comcast interface. What am I missing?
Hello, how are you? I hope your day is going well and my reply reaches you at a good time. My support is limited with owned equipment, but I will be happy to share what comes to my mind. I have a few questions if that's okay. Have you tried logging into your equipment from all devices and if yes, are you experiencing the same issue on all devices? Also, is the issue happening while using a device that is connected with an Ethernet cable?
If you have reset all your devices. Computers, mobile devices, and your modem/router and the issue is still happening while directly connected with an Ethernet cable it may be worth considering resetting your equipment to factory defaults and setting up your network again. I would only do this as a last resort after trying to call the equipment manufacturer.
