XR500 only showing 20mhz channels

I noticed that the only channels I can select from the dropdown in the XR500 DumaOS menu are the 20mhz channels. The 40, 80, and 160mhz channels are not available to select whatsoever. Any idea how I can gain access to these channels?

You can't - because (except in the Wifi Channels Wikipedia, and with some legislation bodies documentation) there are no such channels! The the higher bandwidth is always achieved by using multiple 20 MHz channels, where one of the 20 MHz does act as the primary channel, and the others channels are added as slaves, dynamically in fact, depending on the client capabilities. And I'm not even convinced the 20 MHz channels must be in a direct sequence. Certainly in 160 MHz modes, the two blocks of four 20 MHz channels don't have to be in sequence at all. Don't remember on how the DumaOS UI does show it - the classic Netgear implementation does show a pull-down for the 5 GHz wireless mode, like "up to 800 Mbit/s", "up to 1733 Mbit/s" - this mode defines the max. bandwidth permitted.

What the Wifi Analyzer Apps are showing is mostly a model - and not reflecting any kind of spectrum analyzer capability. No

Last, the max performance you can archive depends widely on the wireless client capabilities, and not on the maximum marketing numbers. There are no 160 MHz capabale mobile devices (so no way to "detect" anyhting the like inn an App, the low cost wireless devices use 1x1 radios, the majority of notebooks and mobiles come with 2x2, few with 3x3 - and virtually none with 4x4.
