Our MR56 AP's are reporting acceptable channel utilization (usually ~2%, up to 10%). However, devices on the ground show much higher utilization with 3-5 SSID's per channel. The AP's are mounted to the ceiling 20 feet high.
Should we manually assign channels based upon what the devices are showing, or leave the AP's in auto selection mode? Should we trust the AP's are devices more? Our channel width is set to 20MHz and using 5 GHz.
In the manual settings for the channel, there is an option for dual 5GHz mode, however am unsure how to enable this. Selecting a different channel changes the active channel, and will not allow us to select two, even in separate lo and hi channels with the 2.4GHz radio turned off.
