Hi everyone - i have an AV600 kit running happily on my home network

however, i've just got an AV500 (WPA4220 v1) WiFi extender 2nd hand....now, when i look on TPPLC i can see the device but it shows without WiFi  settings - DEVICE-490D see attached screenshot. In fact, it would appear from the icon that it has no wifi at all?.

Now, i'm able to connect to the device WiFi using my laptop and phone so it appears to be working ok (entering the SSID/Password on the extender label) - but it wont pick up WPS from my router (eg hold the button on extender fails to connect) - i cant change SSID/Password to add it to my home wifi as it doesnt appear to be wifi enabled on the utility ? i should say ethernet works fine via LAN cable..

anyone help me to add this onto my home network - i cant see a solution!..many thanks...
