b. Verify that the Fan device is connected to the wireless network.
While still in the Config tab, click the Wireless0 interface in the left pane.
In the configuration settings, the HomeGateway network should be listed in the SSID box. Verify that the DHCP is selected in the IP Configuration settings, the IP address is 192.168.25 and the default gateway is 192.168.25. This indicates that the fan is connected to the network and is receiving IP configuration information from the home gateway.
