To whom it concern:

Need guidance on how to setup the WIFI on Hap Ac2 with Router OS 7.20.1 and the latest Winbox.

All guides revere to older setups and there is extra configuration required.

Had to install new OS via Netinstall due the fact that i had parted ways with ISP that used Mikro.

Was not able to export original config

Depends ... is OP going to use wifi-qcom-ac drivers or not ?

AC2 uses wireless out of factory.
