Hi all. I have googled this problem and found tons of similar threads but no real answers...or the answers are so obvious to somewhat-technical people but not the layman. I consider myself very technical but am a bit stumped with the problem that I will detail below. I have 2 3rd gen ATVs...both are using ethernet on CAT6 cabling in my house...using a Netgear WNDR3700 wireless router with gigabit ethernet jacks. If I stream movies from iTunes 10.x on my WinXP box, they play beautifully on the ATVs. If, however, I attempt to use Airplay on my iPhone 4S to play a 30 second (or any length) video that was recorded on the iPhone 4S, the ATVs just sit there and buffer for 5+ minutes and eventually I just give up. Even if I just try to flip through some pictures on Airplay, there is a 5-30second lag! I have even tried a friend's iPhone 5 and the same performance problem exists for pictures and video using Airplay. I have powered off my iPhone, restarted the router, and restarted the ATVs...no change. I have confirmed that the 2 ethernet jacks have blazing speed by using laptops on those jacks to transfer files...my laptops are telling me I have a gigabit connection and the file transfers are approaching 1 gigabit limit. Before this weekend, I was using an old Netgear wireless N router (and the same ATV problems existed then) and finally decided to spend the $$ and buy a new router to see if it would help. In theory the new router should be a lot faster and I thought would have solved this problem...the new router is 1)gigabit ethernet instead of 100mbit and 2)the WIFI in N and dual channel while the old router was limited to G. The WIFI is living up to it's N advertisement as I have tested my laptops transferring files back and forth over WIFI N and the performance is terrific...so I know it's not the router or WIFI interference. Each ATV is only about 25 feet away from the router. So what's the problem? Remember that the ATVs are on gigabit ethernet so I know they have access to blazing speeds. Does Airplay just stink when using iPhones to push video clips to ATVs? Or is there something else? Unfortunately there is no performance/network tests on the iPhone or ATV...that would be instrumental in helping me understand what the devices are actually capable of. 1 of the ATVs was just updated to the most recent software last week (I don't have the version #) while the other ATV is on the software that it shipped with in January 2013. 1)We can rule out the network as it performs just fine both on gigabit ethernet and WIFI N...and the ATVs stream very well from iTunes 10.x on Windows XP 2)This problem exists on 2 ATVs 3)This problem exists on and iPhone 4S and 5 4)It doesn't seem to be ATV software specific as the ATVs are on different versions. If you are using the ATV and an iPhone 4S and/or 5 and have great performance with airplay and videos off the iphones, I would appreciate hearing specifics on your use case and hardware...router make/model, ATV version and software, ethernet vs. wifi, etc. Thanks in advance! EDIT: I also tried putting my iPhone 4S in the same room as my router and the performance was still terrible...so the router isn't too far away and/or poor wifi signal. EDIT 2: Sorry! I meant that I have an ATV 3 All this talk recently about the ATV getting a different chip threw me off.
