Hi. Thanks for replying.
The iMac is in another room, so a long ethernet cable isn't practical. It has a built-in airport, so I use that to share Internet around my home. An ethernet cable is plugged from my modem into the Mac, which then shares wirelessly.
Using WEP, the Apple TV can see when Home Sharing is on, but obviously it's not very secure. That's why I want to switch to using WPA2. But when I do that, the Apple TV can't see that Home Sharing is on.

Have you restarted the AppleTV and iTunes after making the change?
Does it show internet derived icons eg for Movies and TV Shows categories? (i.e. is it getting a connection to the internet but Home Sharing is not working?)

Yes, I've tried restarting the Apple TV and iTunes, it makes no difference.
Internet associated icons - Movies, TV Shows - do appear. So the shared Internet signal is getting through. It's Home Sharing that doesn't seem to work with WPA2.

Hi Brian. Thanks for your reply. Why was your first one removed?
Not that I wish to contradict, but clearly there is something about the use of WPA2 that is interfering with Home Sharing. If I use the exact same setup without security, or with WEP, then Home Sharing works. With WPA2, it doesn't.
I tried pinging the ATV from the iMac. It continually sent and received packets, so it worked.
And yes, iTunes is on.

Very odd. I suspect it isn't the WPA2 itself rather some DHCP or firewall issue with AppleTV not detecting the Home Share correctly.
If you can access the internet then the WPA2 networking is working.
Have you connected via WPA2 then turned off Home Sharing in iTunes and AppleTV, then signed in again on both to refresh credentials?

Tried refreshing the credentials, yes. It didn't make any difference.
As for using my iPhone and iPad, they can see Home Sharing when I have no security. If I switch the iMac to WPA2 Personal, the 'shared' option on both devices disappears.

I recently upgraded my late 2009 iMac to a late 2013 iMac.
Even though I restored my old system, files and everything from the old Mac to the new one, suddenly Home Sharing works with WPA2 Personal.
No idea what the problem is, but there's clearly some issue with older iMacs.
