That's what the Apple tech guy said. He shut me down right away and said that. I tried on my own, posted here, then finally got Apple support on the phone.

I jumped gun with netgear. It's not working too well.

Air Radar has signal at 80% , but the "average" at only 30%.
I don't understand average column, but suffice it to say, the connection is no better than without the netgear extender.

That said, the Netgear has created a 2nd network, with a different name, which is not really extending from my original network. I'm confused what to do to be honest.

I'm going back and forth with Negear by email, which is something you do not want to do in this lifetime if you can avoid it.
