Hello,
I was thinking about upgrading from the hAP ac² to ac³ because of the new high gain antennas for a better Wi-Fi coverage.
I have been comparing other specs to make sure I would not downgrade any of the current ac2 functionalities I currently use.

I compared the FCC Grant of Certification (5GHz) of hAP ac2 and hAP ac3.

For hAP ac2 the ranges are:
5180.0 - 5240.0
5260.0 - 5320.0
5500.0 - 5720.0
5745.0 - 5825.0

For hAP ac3 the ranges are only:
5180.0 - 5240.0
5745.0 - 5825.0

It seems that DFS channels (UNII-2) are missing in ac3 specs, although there were supported by ac2!?

I could not find the official supported Wi-Fi channels anywhere else in the product description.
Upgrading from ac2 to ac3 means losing 5GHz DFS channels?

I contacted Mikrotik technical support in parallel of posting the message above yesterday.

Just received their reply today if anyone else was wondering the same as I did:
"The hAP ac^2 has U-NII-2 channels certified which at the moment are pending for the hAP ac^3."
"At the moment there is no ETA, because due to the COVID-19 situation the priorities were changed and DFS frequency range certification will take longer than expected.
The DFS frequencies will be available by simply updating RouterOS versions."

Looking forward to this.

We need DFS.

Also, updated an Omnitik AC POE today from 6.45.x (I think 6.45.9 came on it, already flashed it tho, can't confirm) to 6.47.7 and lost UNII 1.

What is that about?
