First off, I want to thank everyone who responded to my post with your wise advice and suggestions!
Where to begin?
Apple has no suggestions as to why this problem occurred, but the iOS Tech hinted very vaguely that it may indeed be iOS 9.X and possibly 9.2 will fix it. I figured BT might be the ticket, since it doesn’t need the wireless router to stream audio, but it seems that the professional opinion is that it really only works well up to 30 feet or so. And I defer to your experiences, since it is a bit of voodoo to me, in that regard.
My wireless network is flawless with the Airport and the DL even at 50 feet or more. Only Airplay is not now. Since it is better for me to sit at the back of the venues generally speaking, (FOH is not practical) I need another solution. No G.A.S. The drop of AP sync is a little nerve wracking since I have to spend a few seconds reconnecting the iPod back to AP, when the choir is waiting to start, in front of 100 parents or more.
Since my network is fine other than “you know what” I’ve been thinking of the cheaper solution (6 bucks), of using Tango Remote to control the iPod Touch at FOH (hidden) with my second iPad. No muss no fuss.
I don't have to make a decision until Dec, when all the Christmas concerts start, so lots of time to think. It's not a major priority, although my post does lean that way, sorry. I have cataract surgery coming up on the 12th of this month for my left eye and Dec 23rd for the right eye, so that's just a bit more important. Getting old is getting old!
Once again, I do appreciate all the input from everyone concerned, you've all been very helpful!
