WiFi Setup

Problem Statement

"Is there any way to ping the WiFi devices from my wired network?"

"No. Both are Private local networks. The G-Wifi Primary has a NAT firewall that prevents unsolicited IP traffic from entering on its WAN port. I suspect you have an implementation that is creating a double NAT situation, i.e. the WAN port of your G-Wifi primary has a 192.168.0.x address. G-Wifi is design to assume that the WAN port has a Public IP Address, not a Private IP Address. If you want your hardwired devices to be able to interact with the devices attached to the G-Wifi network, they must all be on the same subnet, i.e. 192.168.86.x and physically connected off a G-Wifi LAN port or switch attached to it."
