I removed the wifi interface manually (...
Tried a factory reset. I tried to upload the firmware and reset it to factory settings - it doesn’t work.
I also tried to create it manually via WUI - it doesn’t work, since there is no way to select a master interface. Same thing through the command line.
How can I restore it?

Check if wifi-qcom package is installed.

If it’s not, you did something more rigid then factory reset (possible action: netinstall but only base package used ?).
You need that package for wifi to work.
Check extra packages on Mikrotik download site for ARM, in there you will find wifi-qcom package.

I checked the packages. The extended package has been installed. But it was the package you specified that was disabled. After turning it on and rebooting the router, the interface created itself. Thanks for the help!
