On the 5 GHz band, set the channel width to 40 MHz and see if that improves reliability. Keep in mind that 80 MHz and 160 MHz channel widths may carry the promise of extra speed, but will also interfere with, and receive interference from, many more sources than 40 MHz.
Read moreWhat is channel bandwidth?
The channel bandwidth is defined as the effective bandwidth multiplied by the frequency reuse factor , where the effective bandwidth is the operating bandwidth that is appropriately scaled by the uplink/downlink ratio.
