Re: Mikrotik RB4011iGS+5HacQ2HnD and WiFi 802.11AC crash interface

I see what you are saying. We have a full dual stack environment as well. All of our radios are set to "auto" for the frequencies and auto (XXXX) for the center channels. Maybe that is why we are not having any issues? We are stuck with US channel space. What app are you using on your Mac to scan th...
