 Some combinations of Country and revision codes are invalid, and will not work together. For example, if you set country to USA, and change only country to "US" and leave revision at "12" that would be invalid. You need to change country / region to "US" and country revision to "0" to have a working combination. Some combinations of Country and revision codes are invalid, and will not work together.

-Beamforming is a performance feature included in Wi-Fi protocols starting with 802.11n.  Beamforming radiates signals more directly towards the receiver, instead of in an omnidirectional pattern, like older equipment. This can result in a higher signal-to-noise ratio and data rates between the two devices exchanging data.+Beamforming is a performance feature included in WiFi protocols starting with 802.11n.  Beamforming radiates signals more directly towards the receiver, instead of in an omnidirectional pattern, like older equipment. This can result in a higher signal-to-noise ratio and faster data rates between the two devices exchanging data.
  
-Traditionally, most Wi-Fi routers and access points included omnidirectional antennas. These radiate radio energy equally in all directions. This is not the most effective/efficient way to exchange radio signals to another device. Much of the signal goes off in directions away from the or other wireless device.+Traditionally, most WiFi routers and access points included omnidirectional antennas.

 With 802.11n, several beamforming methods were allowed, but no standard method existed. A lack of standardization meant beamforming usually provided little performance improvement. With 802.11n, several beamforming methods were allowed, but no standard method existed.
