Doser 2. Possible to use 5ghz wifi connection?

I cant get my doser connected to my wifi.
The thing is, my wifi is only 5ghz i Think. Ore Maybe i just dont know how to make a 2.4ghz connection.

But is it possible to get it online on a 5ghz connection ?

The doser does not communicate on 5ghz.
2.4ghz or LAN connection is required.

Perhaps your router is emitting a single signal which consists of 2.4/5g. If that's the case, there should be a setting which allows you to split that signal so you have a dedicated 2.4 and dedicated 5ghz signal.
