Does a Smart WiFi Plus (booster) support Guest Networks

[Ogram]

I have a Smart Hub Plus extended by a Smart WiFi Plus booster (y'know, if you have to put "Smart" in the name, that tells me everything I need to know about how smart the device is). I have a Guest network configured for IoT devices. However, all the IoT devices struggle with weak WiFi signal. Running around the house with a network scanning tool on my phone, it appears that the Booster isn't extending the Guest (IoT) network, only the Main network. 

So my question is: is this expected behaviour? is the Booster supposed to support the Guest network as well as the Main network?

@AnnaH123 Would have to be something along that line as that Tp is a straight Ethernet Powerline device with no real functionality in it control wise, so a lot will depend on what you can do with the AP that you are using and it's own software if there is any!

@AnnaH123 : If you are not using the Compatible WiFi SSID of your SH+ for anything else you could use that as a guest network & it will be broadcast from the extenders. This would not suit the OP of this thread as it would not be IP isolated unlike the proper Guest network, but it might suit you if you just require a separate WiFi login for guests.
