I am new Miktrotex hEX user. I have recently got the device and installed default configuration. I see bridge interface and ethernet interfaces working good but I can't create new wireless interface. It looks like it needs "Master interface" to be set but dropdown list is empty and I can't select any interface as master. The same problem is for web interface and for WinBox. I have tried various RouterOs versions starting 6.41 up to latest 6.44beta without a luck. Please, help. I really need suggestion.

HEX does not have wireless, you will have to connect a separate wifi access point

Thanks. You are right. I have made silly mistake.
