APX320 on Sophos XGS

This is not possible due the implementation of the APX Hardware. 

I'm currently running my APX320 in dual 5GHz mode and the the one radio is on Channel 100. Which is the trick: the default 2.4 GHz radio can be run in the upper (100+) 5 GHz range, but the default 5 GHz radio will only run in the lower 5 GHz (< 100) range. I gave up 2.4 GHz and left three old devices behind, but dual 5GHz is very nice.

Hi,

ok. i will try this. But i think it will not be possible because my customer(s) often need to have 2,4GHz as well

Yes. There are two radios in the APX320. Radio0 is doing 2.4 GHz or the upper Channels of 5 GHz. Radio1 is doing 5 GHz lower channels. 

So you have to pick between 2.4 GHz or Upper Channels. 

Depending on the customer and how many 320's they have and their spatial layout -- and whether they are maybe a bit over-provisioned in terms of coverage -- you might be able to switch most 320's to dual 5GHz and leave one or two for 2.5/5Ghz. In general, 2.4GHz travels farther and penetrates better, and hopefully you have fewer 2.4GHz-only devices anyhow. (They may even be localized, like some legacy printers or other devices.)
