去掉WIFI 14信道

路径：frameworks\base\services\java\com\android\server\WifiServer.java的218行:
  /**
     * Number of allowed radio frequency channels in various regulatory domains.
     * This list is sufficient for 802.11b/g networks (2.4GHz range).
     */
private static int[] sValidRegulatoryChannelCounts = new int[] {11, 13, 14};
更改为{11,13}或者private static int sValidRegulatoryChannelCounts = new int(13);
 
注意：这样修改后如果一个人买了一个到另外一个国家要用14信道 将会导致用不了14信道。请知悉
