Wi-Fi Performance Optimization (U7 Lite)#

Diagnostic steps for addressing throughput discrepancies between wired (1 Gbps) and wireless (300 Mbps) connections on Wi-Fi 6/6E hardware.

Channel Width: For high-speed Wi-Fi 6/6E, utilize 80 MHz or 160 MHz channel widths on the 5 GHz/6 GHz bands.
Band Steering: Disable Band Steering if it causes frequent client roaming/drops.

Verify Link Speed: Check client-side PHY rates (e.g., netsh wlan show interfaces on Windows) to ensure the client is connecting via 5 GHz/6 GHz.
AP Settings (Unifi/Ubiquiti):
- Mode: Set to HE (Wi-Fi 6) or EHT (Wi-Fi 7).
- Channel Width: Set to 80 MHz or 160 MHz.
- Minimum Data Rate: Set to 24 Mbps to disable legacy (802.11b/g) rates.
Client-Side: Disable Wi-Fi Power Saving mode on Linux clients:
```
iw dev wlan0 set power_save off
```

Addressed a specific case where a U7 Lite was capped at 300 Mbps due to potential client-side or channel width limitations.
