5GHz channels disappeared on hAP ax2

[ToTheFull]

I avoid DFS ranges. No problems.

I can relate to that but in the UK that effectively means you have one 80MHz range 5170-5250. This means that congestion and Tx power become considerations. In the UK, this range has power of 18db on my test hAP ax2. This is significantly less than 5490-5570 which is 25db. The other non-DFS choices of 5735 and above are even worse with Tx power of 9db plus not usable by some client devices.

I’m about 15 months ahead with a Hap AX2 and Cap AX, UK based and can relate to a lot of what you are now calling out.
Even tried to get the upper frequency power levels changed but sadly Mikrotik don’t appear to want to change the power levels for the upper frequencys to solve some of the problems you are having with Radar etc. Have a look here http://forum.mikrotik.com/t/power-tables-for-uk-incorrect-for-5725-5850/170149/1 it should be 200mw for the Uk 5745-5805 not 20mw which would give another 80-wide option none dfs. Also a quote in the above thread even says that Ubquiti products in the uk give 200mw for those frequencys.
