In some regions, not all channels are available. Do not change the channel unless you 
experience interference (shown by lost connections or slow data transfers). If this 
happens, experiment with different channels to see which is the best. 
When you use multiple access points, it is better if adjacent access points use different 
channels to reduce interference. The recommended channel spacing between adjacent 
access points is four channels (for example, use Channels 1 and 5, or 6 and 10).
10. To change the mode, select it from the Mode menu.
Up to 145 Mbps is the default setting, which allows 802.11n and 802.11g WiFi devices to
