Hi @Shane ,
We have the similar issue. We were on ADSL and have a WN2500RP Netgear Wifi Extender which worked fine previously. We then changed over to NBN and were given a (N300 nf12 Netcomm Router) , and cannot for love nor money get the two to talk to each other over wifi. I've tried to connect with WPS, through the wizard and manually - no joy. I managed to get the extender to work but only if the ethernet was plugged into from routher to extender. This is not feasible as the FOX IQ is downstairs some distance away from the main router, and that is also where the blackspot is.
Any direction on setup would be greatly appreciated as it's drivig us NUTS !!
