Solution (not a workaround) to the issue of not accessing the SB8200 Webinterface
I have been banging my brain out trying to get my Linksys MR20EC router to access the SB8200 modem's webinterface. Every thing I have tried based on available information on the web did not work. And I mean everything. This method does not require you to touch your primary router, you know, the one that will not allow you to view your modem's webinterface. All this was tested with two older router/AP boxes and it works. This is specifically for the Arris SB8200 which has two ethernet ports. If you modem only has one, sorry, I can't help you. Here is a solution that does work. You will need another router, or a wifi extender that can work in AP (access point) mode. The SB8200 has two ethernet ports,you will connect the second router/AP to the open port. Please read this through twice so you have a mental picture of what you are doing. Configure the spare router or wifi extender (in AP mode).IP Address:192.168.100.2 Mask (if asked): 255.255.255.0 Gateway: 192.168.100.2 DHCP: 192.168.100.
