Invalid value in Master Interface

Can’t create WiFi of VirtulAP interface due to empty “Master interface“ field. Can’t get what should be there.

RouterOS 7.20

It needs to name one of the physical wireless interfaces.

It’s a drop-down; do you not get a choice of these?

The list is empty. hEX S fresh out of the box. No changes made - just updated routeros package and installed wireless package.

Fully reset it and check it again.

hEX S? Neither hEX S (2025) or hEX S has wireless interface.
