Guest Wi-Fi not working when BGW320-505 gateway is in passthrough mode
My BGW320-505 gateway is in passthrough mode connected to a managed firewall/router for my LAN. I've enabled Guest Wi-Fi on the gateway for access to the Internet but not to my LAN. The AT&T Smart Home Manager cellphone app shows that Guest Wi-Fi is enabled (button on right and shows green) on the "My Wi-Fi" page but the "Wi-Fi name (Guest)" SSID I've entered doesn't show up as an available network on any device. Also, there doesn't appear to be any way to chose the Wi-Fi channel for guest access. Does "Guest Wi-Fi" not work with the gateway in passthrough mode? If not, is there an alternative or workaround?
