Comment changer la fréquence du WIFI de l'ordinateur

Answer 1

Thanks for reaching out! Try to force Band via Wireless Mode (works even when “Preferred Band” is missing)

Many adapters hide band control under Wireless Mode instead.

Win + X → Device Manager

Expand Network adapters

Right-click your Wi-Fi adapter → Properties

Go to Advanced

Look for:

• Wireless Mode
• 802.11 Mode
• HT/VHT Mode

Set one of these:

802.11a / 802.11ac / 802.11ax → forces 5 GHz

802.11b / g / n → forces 2.4 GHz

Click OK → Restart Wi-Fi.

This bypasses the missing Preferred Band option entirely.

See if this helps. If you need further assistance just let me know.

Best regards,

Kimberly
