Link Tuning

Tune the link only after the basic WFB-NG setup works reliably. Changing MCS, FEC, channel width, bitrate, or power on unstable hardware makes troubleshooting much harder.

Start from presets

Use OpenIPC Companion presets first. They provide known combinations for WFB-NG and camera settings and are safer than editing every field manually.

Fixed profile tuning

A typical conservative baseline is:

  • bitrate: 4 Mbps;
  • channel width: 20 MHz;
  • MCS: 1;
  • FEC: 8/12;
  • guard interval: long.

This is not the highest quality profile, but it is a reasonable baseline for testing.

Adaptive Link can switch profiles automatically based on RSSI and SNR. Use it when you already understand the base link behavior and want automatic fallback between quality and range profiles.

Bitrate calculator

Use the WFB-NG Bitrate Calculator to estimate combinations of bitrate, channel width, FEC, and MCS before applying settings to hardware.

40 MHz warning

Do not enable 40 MHz mode on adapters that do not support it. EU-based adapters cannot transmit in 40 MHz mode, and some BU-based adapters have the same limitation. See EU/BU 40 MHz Issue.
