I don't have AirPort Utility on my Windows 7 laptop.

I have a Netgear Extender located in the middle of my house to take my WIFI signal to the far end of the building. I can log in using my IPhone or iPad but I cannot open FaceBook or Netflix on either device when I am in the far end of the building depending on the extended network. Any ideas on how I can fix this so I can use all the aps on my Apple devices?

The articles sent to me by Apple support gave instructions for using the AirPort utility but I don't have this on my laptop.

Thanks for any help you can offer.
