The IOGEAR Universal Wi-Fi N Adapter allows you to connect an ethernet device to your network via wifi.
You plug the adapter in to the ethernet port and use WPS to connect to your wifi.
I configured the wifi adapter and tested it using a laptop so I know the adapter is working.
But when I connect the adapter to my VoiP phone the phone can't connect to the network.
