  1. “Wirelessmon” will detect the distribution of wireless channels in the environment.  If the channel color is either red or yellow, it means there's strong wireless interference on the channel. If the channel color is either green or blue, it means there's weak wireless interference on the channel as shown in Figure2:

  1. Choose a 2.4G wireless channel among Channel 1, 6 or 11 if neither of them in the above figure is red or yellow. Otherwise, choose the channel with the shortest bar as your 2.4G channel.
