I have 2x hap ac2,
The first one connected to the internet I works fine
The other one I want use as an extender, I have the wired connection to each other but don’t how to configure it. All the tutorials use an other version of winbox, I’m currently using 7.4
I don’t want to mess with first one if possible

I’m really new to this, there were other forums on this but I couldn’t understand how to do it so try to be detailed and simple as possible.

Thanks, Daniel

Assuming that you are talking about WiFi extender look for CAPSMAN configuration examples.

How do I get here?

If you do not want to manage two separate AP please visit that: https://wiki.mikrotik.com/Manual:Simple_CAPsMAN_setup

Recommend moving to 7.16.2.

Do you simply mean that the second device is connected to the first device by ethernet cable and you want to us the second device as an AP/switch ??
