How do I get an Apple onto my new network?

[Standard]

I just bought a Netgear R6850.  A nice guy from my internet provider spent about half an hour helping me to get internet on my Windows 7 machine. 

How to I connect my wife's Apple to the new network?  At 88, this stuff isn't obvious to me.

Thanks for the help.

   Ask him about the "Apple"?

   "my wife's Apple" is a bit vague.  Some kind of Macintosh?  iPad?
iPhone?  Which operating system version?

   It's really an Apple qustion, not a router question.  Start at
apple.com?

   If you had an old network, then it might have made some sense to
configure the R6850 to use the same SSID and passphrase as the old
network, and leave your computers/devices alone.  _That_ would be a
router question.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look for
"Specify Basic WiFi Settings".

   But if changing the Windows system once was an ordeal, then changing
it back might not be the easy way out.
