Local Transfer Troubleshooting & Requirements

For optimal high-speed WebRTC transfer on the same network:

AP Isolation / Guest Wi-Fi: Public or guest networks often block device-to-device communication. If connection fails, switch to a main Wi-Fi or turn on a Mobile Hotspot.

Browser mDNS: Browsers mask local IPs for privacy. Ensure both devices are actively online during initial session code pairing.

Firewall Rules: Ensure local firewalls allow outgoing/incoming UDP traffic for WebRTC P2P streams.
