On the computer that you are using to access the product, configure the Ethernet interface to a static IP address on the same subnet as the wireless access point (e.g., 192.168.0.5). If you have connected our product to your network already, it may have obtained a DHCP address. In this case, disconnect it from the LAN and use the reset button on the PoE injector to restore the default settings. Then, connect it directly to the computer for configuration. Once complete, connect the wireless access point to the network.
