Hi,
I found a configuration issue with the new Wifi drivers and AX devices with CAPSMAN. I set up 4 Mantbox 15S AX's last week at a caravan park and found their performance to be lacklustre and the complaints started to roll in. They should be stellar compared the the 10yo Metal 2N's they replaced, right?
I noticed their transmit power level on 2.4GHz was being reported at 7dBm with default power settings, which seems too low in contrast to the 5GHz 15dBm level. Further digging showed the 2.4GHz Current Max Reg Power to be 20dBm (too low) and 5GHz 36dBm (fine). Today I changed the 2GHz config from Australia to USA and the level sprung up from 7dBm to 23dBm. Add the 12dB gain of the Mantbox's antenna and you get close to the class limit of 36dBm-EIRP. Amazing! Correspondingly the hapax2's in the site office and here at home as well have shown a big improvement too. Using the Wifi developer tool built into my Samsung phone I can see a +10dB signal change when I swap from AU to USA on the hapax2 here.
I think Mikrotik have erroneously applied a wrong limit of 20dBm at 2.4GHz for Australia (it's that low level in many other countries) and it should be set to 36. USA appears to be 30 (1000mW EIRP) and Australia should be set to 36dBm (4000mW EIRP) so there is more gain to be had once it's corrected.

Just curious about something.
We needed some ad-hoc wifi in a small raked theatre with perhaps 30m
through clear air in a straight line-of-sight from the control room
(sound and lighting decks) to the stage.
An hAP ac2 was losing connections all the time at that distance. An old
RB951Ui-2hND was solid.
The doco says the 2.4GHz transmit power differs - 30/25/30/23 vs
27/24/27/23. Is that difference enough to explain the dropouts? Why
would the newer device have so much less power? Needed to share it with
the 5GHz side perhaps?
Both are running 7.15.1 BTW.
Regards, K.
