I am trying to enable the built in MoCA adapter on my SBG6782-AC arris surfboard. I follow the instructions on this article: https://arris.my.salesforce-sites.com/consumers/articles/General_FAQs/SBG6782-v8-4-x-MoCA-Setup

However, on the web interface when I customize the settings to enable the built in MoCA adapter, most of the lights on the router turn off, and it stops working and I cannot connect to it or get back into the web interface. I have waited over 30 minutes and the router still was not working. The only way I was able to fix it was by factory resetting it, but then the MoCA setting was disabled again. Anyone know how I can turn it on and still have the router work?
