iOS 6 home sharing and airplay not working
I have an iPad 2, iPhone 4S and iPhone 4 - all of which I upgraded to iOS 6. Now Home Sharing and Airplay is not working on any of the devices. I have an iPad 1 which still has iOS 5 on it, and two 2nd gen Apple TVs - which continue to work perfectly using Home Sharing and Airplay. All iOS 6 devices connect to the Internet via wifi and they also connect fine to iTunes and the App Store. I have rebooted my PC, reinstalled iTunes, restored my iPad and reinstalled iOS 6, reset my router, reset network settings on my iPad but have now run out of ideas. Any ideas? Also, would be interested to know if anyone does have home sharing working on iOS 6. (In case it helps, I have windows 7 64 bit pc with latest version of itunes and a sky sagemcom wireless n router with latest firmware).
