Buffalo AirStation explained

Buffalo AirStation is the name given to a series of wireless LAN equipment sold by Buffalo Technology.

Products

• Residential gateways
• Wireless LAN cards

Use with third party firmware

Many of Buffalo's residential gateways use Broadcom microprocessor chipsets, allowing a variety of third party open source firmware to be installed. Some of their most recent routers with Atheros-based chipsets are shipped by Buffalo with a branded version of DD-WRT already installed.^[1]

CSIRO controversy

In late November 2007, Buffalo announced they would temporarily stop supplying wireless LAN products in the USA due to the ongoing lawsuit filed by the 802.11a, 802.11g and 802.11n patent holder CSIRO.^{[2] [3]}
