itunes wifi sync not working
I have iTunes 12 installed on my win7 computer. iTunes works fine and Im able to access the iTunes store. my apple devices sync fine to iTunes via the usb cable. However, Im unable to get any of my devices to sync over wifi - even after following the instructions and setting up wifi sync on iTunes.
I have run the diagnostics on iTunes and notice that it does fail the "Secure link to iTunes store failed" test - this in spite of the fact that I can in fact access the iTunes store quite fine from the pc. I have confirmed that there is an inbound windows firewall rule allowing access to iTunes. I have also tried disabling my antivirus (avg) to no effect.
