If you have a WPS button on your extender you may be able to get it to sync with the Virgin Superhub as follows:
Make sure the bottom green LED on the router is on.
Press the WPS button on the extender.
Hold in the large "Virgin" button on the front of the router for 2 seconds it should alternate between red & blue. The two should then sync.
If this doesnt work then you will have to do it manually in which case you will need the passphrase which is on a label on the back of the router and your extender manual for instructions. There is information on the Virgin website re the Superhub.
