How many WiFi networks are active in your vicinity? Yes I have several good WiFi monitor apps on my MacBook Air If the network hasn't changed, maybe other networks have jumped on the channel I was using.Ĭlick to expand. Not totally sure why this happens, but assume that it was due to network contention. I check my network settings and see that my Apple TV has changed its network (I have 4 possible networks to connect to) to one of my slowest ones. I check and the bandwidth has dropped <10 Mbps. Things will be working fine, then all of a sudden I get buffering. Even though I have a good wireless network (~400 Mbps at the Apple TV) there are huge variations. If you can install the developer HUD for many video apps it will display the network bandwidth that the Apple TV sees. However there are some 5.0 channels which offer good connectivity:Ĭurrently I am connected to the 5.0 GHz channel one, and I am the only one on that channel. All of the 2.5 channels have poor quality due to network saturation, up to 10 networks sharing the same channel. I have some 52 networks active in my vicinity. Are you connected to a 2.5 or 5.0 GHz network? How many WiFi networks are active in your vicinity?Ģ. Possible, but the least likely point of failure.ġ. Has anybody else had similar problems with their Apple TV? This indicates a problem with the Apple TV. I replaced the Apple TV with an iPad using a Lightning Digital AV Adapter and over several days with many hours of video streaming there has been NO buffering. Prior to the restart, WiFi speed measured on the Apple TV is ≈ 1-2Mbps while the speed measured by the iPad located beside the Apple TV is ≈ 40Mbps. The WiFi speed measured at the device location is ≈ 40Mbps on both Apple TV and iPad.Īfter streaming for ≈ an hour and a half buffering occurs and sometimes the program can't be restarted, requiring the Apple TV to be powered off and then restarted. I also have the same app on my iPad and iPhone. I have also added a WiFi speed measurement app to the Apple TV. I have a fibre to the node broadband connection. I have tweaked my modem/router to get the best possible WiFi speed at the Apple TV's location. Then it lasts for another ≈ hour and a half before buffering again. It seems the only option is to power off and restart the device. After about an hour to an hour and a half the video stream starts to buffer. I have an Apple TV, 4th Generation with 32Mb of memory.
