Deco X50 guest wifi - no internet access
I recently purchased a set of 3 Deco X50 units and they work really well!
I'm running them in AP mode (because my ISP modem/router doesn't support modem-only mode, and it includes a proprietary VoIP adapter that provides our landline telephone, so can't easily be removed).
The Decos all connected via ethernet into a TP-Link unmanaged switch. The router is a Sky SR204 with DHCP enabled and WiFi disabled.
I've just tried to set up the Guest WiFi and while it works, if I select to 'Isolate From Main Network', the guest network can no longer see the internet.
I appreciate that this isn't using VLANs, or a different subnet, but is someone please able to explain how the guest network becomes isolated, and also why it can't see the internet?
