I have Sky FFTP and have set 3 Deco X50s in access point mode with the main one wired into the Sky router.  One of the other satellite Decos is connected via an ethernet cable running through an unmanaged switch.  The setup works flawlessly and every device has been able to connect to the network.  However, my PlayStation portal will not connect and when I try it asks for "additional authentication" and fails to connect.  On some attempts, a QR code appears on the portal briefly and then disappears - either way the portal cannot complete authentication as it doesn't have a web browser.  Any suggestions before I return these devices for a refund?
