Question about Ubiquiti Cloud Gateway Max

It has neither WIFI nor WLAN... What you have found is that you can set up WLAN / WIFI networks in the configuration. But you can only do this if you have at least one Unifi access point in use.
Again, this is a gateway, it is clearly known and not the idea that this has WLAN / WIFI

This is known beforehand. If it doesn't work, then simply buy a Fritzbox, as WLAN is directly integrated.

Is that a question or a statement? The Cloud Gateway Max does NOT have WLAN!

No, it is not 'missing'. It is simply a gateway and not a WLAN router. I don't expect WLAN.

Sorry... I meant WIFI. It has WLAN but no WIFI
