Client Capabilities Test

Test browser WebRTC, WebSocket, audio, and network before connecting

Connectivity

WebRTC, NAT, and firewalls

My browser says it can't connect

Verify your network allows outbound UDP and access to TURN/STUN. Try another network or a wired connection. Confirm the gateway is online. Run the Client Test to diagnose issues.

Control UI is slow or unresponsive

Close background tabs, use a modern browser, and ensure the gateway host has enough CPU. Prefer wired Ethernet to Wi‑Fi.

Audio

Devices & quality

I can’t hear anything

Allow audio permissions in the browser. On the gateway, select the correct audio input/output devices and verify levels. Check the radio’s AF/IF output.

PTT not working

Ensure you have TX permission, verify CI‑V/PTT settings on the gateway, and confirm the radio’s transmit inhibit is disabled.
