Hi, I just got a Mikrotik hAP ac3 with RouterOS v7.8 installed. I read in the Aredn docs that I need to downgrade the RouterOS to v6.x and then flash the Aredn FW. I've also read that you can not flash the ac3 with a version of the RouterOS earlier than what came from the factory. So it seems I should send this back for a refund, if I understand correctly. Much of this knowledge is from the OpenWrt page on the subject. I've successfully flashed 6 hAPac Lites, 4 SXTsq5ac and 2 SXTsq lite 2 nodes, so I know the process. Does anyone have recent practical experience or advice? Thanks in a
