EX7000 extender connection to SAGEMCOM router and NBN

Followed extender set-up steps to the letter.
1) Moved the extender within 2 feet of router.
2) Reset the extender. LEDs blinked Orange.
3) Pushed WPS button on extender (LEDS blinked Green)
4) Pushed WPS buwton on router (LED blinked Green)
5) After approximately one minute LEDs on both devices turned solid green (Devices paired?)
6) Used mobile phone and found OPTUS_A43FD3_2GEXT SSID and connected succesfully to it.. My router's SSID is OPTUS_A43FD3. I did not find NETGEAR EXT. I am assuming OPTUS_A43FD3_2GEXT SSID was created on a previous attempt.
7) Logged into the Netgear Set-UP page. Found Wifi network and router SSID, clicked on the 2.4GHz check box and clicked NEXT.
8) Entered router SSID and password successfully.
9) Clicked NEXT button.
10) Used the mobile phone (which was connected to OPTUS_A43FD3_2GEXT SSID) and started to browse Internet Web Sites.
11) Unsuccessful. (Error message "No Internet Connection" appears.
12) Repeated steps 1-11 many times including resetting the router beforehand but no connection.
