Network Diagnostic Guide for Streaming

Use this guide to run basic technical checks on your network when streaming apps are buffering, dropping quality, or failing to play content reliably.

For app-specific troubleshooting (including Peacock TV), see the main help page: Peacock TV Installation & Troubleshooting – Independent Help

1. Check speed, stability, and latency

  1. Run a speed test using a browser or phone (test from the same network your streaming device uses).
  2. Note download speed (ideally 10 Mbps+ for HD, 25 Mbps+ for 4K), upload speed, and ping.
  3. If ping is very high (>80–100 ms) or speed is unstable between tests, your connection may be congested.
  4. Test with another device to confirm if the issue is network-wide or device-specific.

2. Router and Wi-Fi troubleshooting

  1. Power cycle the router and modem: unplug for 30 seconds, plug back, wait 2 minutes.
  2. Move the streaming device closer to the router or remove obstacles between them.
  3. Switch from 2.4 GHz to 5 GHz Wi-Fi if available, or test a wired Ethernet connection.
  4. Disconnect devices that are downloading large files or streaming at the same time.

3. DNS and advanced checks (optional)

  1. Temporarily switch DNS on your router or device to a well-known public DNS (e.g. 1.1.1.1 or 8.8.8.8).
  2. Ensure there is no active content filter, firewall rule, or parental control blocking streaming traffic.
  3. If you use a VPN, disable it and test again to see if routing is causing the issue.
