I have an Apple TV with Airtunes enabled. But apparantly, it's not possible to connect to it from PC's who are connected to LAN with cable instead of WiFI? Does anyone know why? More details: I have 3 PC's: PC 1: , Windows 7 64-bit with iTunes 188.8.131.52 (latest) Stationary, connected to LAN using cable in a Gigabit switch PC 2: 100% fresh install of Windows 7 32-bit and iTunes 184.108.40.206 Stationary, connected to LAN using cable in a Gigabit switch PC 3: Win 7 32-bit with iTunes 220.127.116.11 Netbook - connected through WiFi Apple TV device (latest firmware) is connected to same LAN using cable as well. All PC's can ping the Apple TV without problems. So the problem is that iTunes doesn't find the Airtunes device (the output dropdown selector doesn't show up). I first tried on my main PC (PC1). It didn't work, so i tested on PC2 (wich is a fresh install of both OS and iTunes!), but same problem there. But then the weird thing happened. I tried to install on my netbook, and it worked! Only difference is that the netbook was connected through WiFi. I don't see why that would matter, but just for fun i tested to disconnect WiFi, and connect with cable and boom - airtunes selection dissappeared! As soon as I disconnected the cable and reconnected WiFi, it appeared again. Why on earth would Airtunes only work on WiFi? As you can see on the attached screenshot, network configuration is equal on Wifi and cabled connection.
