How to Protect Your Chromecast from Other Users on a Shared WIFI Network Using a WIFI Extender

[ElliottBeils]

How can I create a separate WIFI network using a WIFI Range Extender that prevents other users from accessing my Chromecast device?


I have a Netgear EX6120 WIFI Range Extender that I use to connect to a shared WIFI network in a holiday apartment. I have set a custom password for the extender network, but I still face the issue of other users being able to stream content to my Chromecast device that is connected to the extender network. This is because the extender network is not isolated from the shared network, and the devices on both networks get their IP addresses from the same router. I do not have access to Ethernet or the router settings. Is there a way to isolate the extender network from the shared network and prevent unwanted streaming to my Chromecast device?
