Wifi Sync and Windows8

Hello everyone,

I've been having a problem with iTunes wifi sync feature. It hasn't been working since iTunes 11 was released and my devices upgraded to iOS 6.0+. The only time iTunes recognizes my iPhone or iPad 2 is when they're directly connected to my desktop. Is there any way to fix this? Could this be related to iTunes running on a Windows 8 machine? I've read through multiple posts about people having problems with this, so I'd appreciate any help in fixing this!
