Troubleshooting: Warning 20005 – Low Available Bandwidth
Technical Breakdown
| Warning Code | 20005 |
| Type / Category | Warning / Miscellaneous |
| Products | qualityRTC |
| Message | Your device estimates low available bandwidth for video calls. Check for UDP network traffic throttling. |
What is this about?
Your device is detecting that the available internet speed is insufficient for a high-quality video call. While the connection is active, the limited data capacity may result in lag, blurry video, or audio dropouts during a TytoCare visit.
Possible Causes & Suggested Actions
- Network Congestion: Too many devices are using your network at once.
Action: Disconnect other devices or pause large downloads/streaming. - Weak Wi-Fi Signal: Your distance from the router is affecting performance.
Action: Move closer to the Wi-Fi router or use a wired Ethernet connection. - UDP Traffic Restrictions: Corporate or school firewalls often throttle UDP traffic, which WebRTC uses for video.
Action: Contact your IT department to see if UDP traffic is restricted. Disable VPNs or personal firewalls to test the connection. - ISP Throttling: Your internet provider may be limiting speeds during peak hours.
Action: Restart your router or contact your ISP to verify your speed plan.
Administrator Note: If this warning persists despite high speed-test results, the issue is likely UDP Throttling. Ensure that the network is not treating real-time media traffic as low-priority “bulk” data.
