XR500 Wireless Question

[revoit]

On the XR500 dashboard Wireless Status it says Channel: Auto(5(s)+9(p)) for 2.4ghz and this seems to be 40mhz if I am not mistaken. And then for 5ghz which seems to be 80mhz channel width it has 149+153(p)+157+161. Does the 's' and the 'p' stand for primary and secondary? For 2.4 ghz, there are 2 channels 20mhz channels that combine to make the 40mhz bandwidth. For the 5 ghz I assume the process is similar. For 2.4 ghz, is the channel 5 and upper, or is it 9 and lower? And for 5ghz is it 149 upper or 161 lower? Both of those upper lower questions obviously in the syntax that I stated in the beginning: Auto(5(s)+9(p)) 2.4ghz and 149+153(p)+157+161. I've also noticed that 149-161 in general is a common range for 80 mhz.

Primary and Secondary yes, I think the primary is the upper but I can't be certain, it's a NG implementation
