High quality lossless audio transfer requires a large bandwidth. Therefore, a stable Wi-Fi connectivity is essential for seamless audio streaming by AirPlay.

Below are some tips for better audio streaming connectivity:

• Upgrade your Apple device to the latest iOS version.   

• If you have opened many apps on iPod touch/iPhone/iPad, close the apps from the multitasking bar.
  • Minimize the number of apps that are running on your iPod touch/iPhone/iPad. 
      
• Minimize the sharing of Wi-Fi connections by multiple devices.
  • When there is internet connection activities (such as web browsing, social network access, email checking or usage of IP (internet protocol) camera through the Wi-Fi network, network connection could be occupied and this might affect AirPlay audio streaming performance.
     
• If the router offers “Auto Channel Scan” option, enable it.
  • This minimizes Wi-Fi connectivity interference, especially when there are multiple Wi-Fi networks in the vicinity.
     
• If you are using AirPort Extreme, make sure “802.11n (802.11b/g compatible)” is selected for Radio Mode.
  • Do not select options with “802.11n only”.
     
• Upgrade your Airplay device 
  • Check the support page for the new firmware availability, and then update if there is any.
     
• Take off any metal protective case from the Apple device 
  • AirPlay performance would be affected if the Apple device is shielded by metallic material.
     
• If the router offers “Wireless Intelligent Stream Handling (WISH)” option or “Quality of Service (QoS)” option, enable them.
  • This would improve AirPlay streaming performance.
     
• If the Bluetooth feature of any device in the vicinity is on, turn it off. 
  • This would improve AirPlay streaming performance.
     
• Check the firmware version of your router. 
  • Please contact your router supplier to upgrade the latest firmware version.
