My Apple TV Gen 2 has completely stopped working via Airplay and Home Sharing. We own many Apple devices (iPhones, iPads, MacBooks) and it doesn't work with any of them. I've attempted wiping it back to defaults with no luck. I have no problem accessing the Internet from AppleTV and my wireless access point config hasn't changed in years. I can ping it from other devices and ports are wide open on my home LAN. I work on large enterprise networks daily and am very technical...yet this little device has me stumped. Any ideas? Thanks in advance.
