Netgear Extenders Not Working with New Altice UBEE Router

Yesterday the cable company (Cablevision/Altice) replaced my defective router with a UBEE router.

Now both of my Netgear extenders are not working.

I followed the connection instructions/video using the WPS button option on both the router and the extenders.

The extenders appear to connect as all indicator lights go green, they show as a active WiFi option, however I cant connect to them.

Any info is appreciated.
