There are several reasons why your Roku might not be showing up as an AirPlay destination on your iPhone. Here’s a troubleshooting guide:

1. Check Compatibility:

• Roku Model: Not all Roku devices support AirPlay. Ensure your specific Roku model is compatible with AirPlay. You can find this information on the Roku website or in the device’s user manual.
• Apple Device: Make sure you’re using a compatible Apple device (iPhone, iPad, or Mac) with AirPlay 2 support.

2. Network Connectivity:

• Same Network: Both your Roku and Apple device must be connected to the same Wi-Fi network.
• Wi-Fi Signal: A strong and stable Wi-Fi signal is crucial for AirPlay. Try moving closer to your router or using a Wi-Fi extender if necessary.
• Router and Modem Restart: Restart your router and modem. This can often resolve temporary network glitches.

3. Software Updates:

• Roku: Update your Roku device to the latest software version.
  • Go to Settings > System > System update > Check now.
• Apple Device: Update your Apple device (iPhone, iPad, or Mac) to the latest iOS or macOS version.

4. AirPlay Settings:

• Enable AirPlay on Roku:
  • Go to Settings > AirPlay and HomeKit > AirPlay.
  • Ensure AirPlay is enabled.
• Require Code:
  • You may need to enter a code on your Roku when trying to AirPlay from your Apple device.

5. Restart Devices:

• Restart all devices: Restart your Roku, Apple device, and router.

6. Other Troubleshooting Steps:

• Enable Fast TV Start:
  • Go to Settings > System > Fast TV start.
  • Enable this feature to allow your TV to turn on quickly when using AirPlay.
• Enable Device Connect:
  • Go to Settings > System > Advanced system settings > Device connect.
  • Ensure “Enable ‘Device connect'” is checked.
• Reset Network Settings:
  • As a last resort, try resetting your Roku’s network settings.
