The WA4020 Wifi adapter is compliant with IEEE 802.11 B+G. This means it can work in both 802.11b (maximum raw data rate of 11 Mbit/s ) and 802.11g (maximum physical layer bit rate of 54 Mbit/s).

It has "FCC ID: KFY-WA4020" wording on the sticker. You might want to make sure your Wifi adapter has the correct FCC number before you proceed to download and install this driver, as using a driver not meant for your hardware might crack your system and you might lost valuable data and maybe need complete reinstallation of your operation system. Always do backup before making changes to your PC system.
