TG1682G Disable All Wi-Fi Including Hidden Networks - Need Help!

I need to disable all Wi-Fi signals on my TG1682G including the hidden networks.  They're causing massive problems, making the gateway unusable to me.  I have WiFi analyzer and I've done my homework.  I've turned off the public WiFi networks, xfinitywifi, and enabled bridge mode but the gateway continues to broadcast.  I tried to request help from customer support but chat is down and the Xfinity store is closed.  How can I get some help?
