I would like to add a Ubiquity Unify Wi-Fi access point to my network. The AP and the BT Home Hub 5 would be broadcasting the SSID. I would like to know if the guest network mode on the Unify AP will correctly isolate the guest network from the main network since I don't think the HH5 supports vlans and I'm not sure if that's how the unify does it? Would the unify guest network also isolate itself from other devices plugged into the HH.
