I have the WPA 8630P KIT power line extender and I am not able to get internet on it.

it was up and running in my old house but has been sat in a box for a few years. I decided to get it out and reinstall it to boost the wifi around my house and also to give me a LAN port on my home office.

I reset both the adapter and extender before beginning and managed to successfully pair them. The extender shows 4 green LEDs, the only one not on is the LAN as no cable inserted. I can find the wifi signal and successfully input the password to connect, however my MacBook shows no internet on the extender wifi. I also tried a LAN cable into a windows laptop and it also showed no internet.

any ideas?

thanks
