Most any WAP (Wireless Access Point) will support a "client" mode.
Normally a WAP is used to provide wireless devices a connection to a wire network.
In "client" mode a WAP is used to provide devices on a wired network a connection to a wireless network.
It sounds as if this IOGEAR device is intended to function by default in "client" mode (it may only have "client" mode) so it should, in theory, work just fine.
