I purchased one of these for $75 earlier this year and have been using it on my XBOX 360 as a wireless bridge. Works very well after a few teething moments during setup. Beats paying over $100 for the official XBOX version. For $25 each I went and picked up 2 today, one for my old XBOX and one for a mate for Christmas.

The Wireless Pocket Router/AP might be small in size, but is huge in functionality. The DWL-G730AP supports multiple operation modes including: Access Point (AP) mode to create a wireless connection; Router mode to share an Internet connection; and Wireless Client mode to connect an existing wireless network. Easily switch between these modes by using the 3-way configuration switch located at the bottom.
In AP mode, the DWL-G730AP can be used to create a wireless network in a room where a single Ethernet port is provided. Now multiple wireless clients can connect to the network at the same time to share resources and files.
In Router mode, the DWL-G730AP can be used to share a single broadband Internet connection, such as in a hotel room. The internal DHCP server automatically assigns IP addresses to ensure everyone in the room can connect to the Internet. In addition, the DWL-G730AP supports VPN Pass-through and firewall features including Network Address Translation (NAT) and MAC filtering to protect your wireless network from malicious attacks.
How did you manage to pay $75 if the page says the retail price is $54?
