Customer Reviews of Buffalo AirStation WLAE-AG300N IEEE 802.11n (draft) 300 Mbps Wireless Access Point
I used two of these to convert an Ethernet WAN port on a router into a wireless connection. This allowed me to use a Sprint Overdrive device as the Internet provider for my network of Ethernet devices. It worked great. Not the easiest instructions but I was able to get it working by using the Ethernet converter Manager software that comes with the unit.
