The WAN Interface will then need to be configured. In this example, the WAN interface will obtain its IP address by DHCP.

In the Wireless Basic Settings the Mode needs to be set to ‘AP’, and the Disable Wireless LAN Interface checkbox needs to be

unchecked. The SSID can also be changed at this point, if desired.

These settings enable a basic routing access point.

Access Point Client Mode

This device can be configured as a wireless Ethernet adapter. In this mode, the device can connect to the other wireless

stations (Ad-Hoc network type) or Access Point (Infrastructure network type) and you don’t need to install any driver.
