My wife's laptop only had a 2.4Mhz card. Received this and plugged into the USB port. Followed the instructions and installed myself. Works on both 2,4 and 5 bands. It receives 170 to 185 MB/s in the 5 MHz band over Wi-Fi from a wired system running at 305 MB/s. Pretty cute stuff! (Don't forget to go back to settings and turn off the old Wi-Fi card and set it as default).
