Laptop is unable to connect to 5G Wifi network

[Faraz224]

From last few days, my laptop is unable to connect to the 5G Wifi network installed at my home. I have a dual band WIfi router which supports both 4G & 5G network. But my laptop connects to the 4G network only. I have set the preferred band as 5G  in network adapter settings but it fails to connect to it. I have a Mediatek MT7921 WIFI 6 802.11ax PCIe Adapter in my laptop. So please provide a solution to this issue.

@Faraz224, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Since your HP Pavilion 14-dv2000 has a MediaTek MT7921 Wi-Fi 6 adapter, it should support 5GHz networks, and you've already set the preferred band to 5GHz — good step.

If the 5GHz network is no longer connecting but was working before, let’s go through a step-by-step checklist to isolate and resolve the issue:

Confirm 5GHz Network is Working on Other Devices

• Try connecting your phone or another laptop to the 5GHz band.
• If they can't see or connect either, the issue may be with your router's 5GHz signal, not your laptop.

Forget and Reconnect to 5GHz Network

• Go to Settings > Network & Internet > Wi-Fi > Manage Known Networks.
• Remove or “Forget” both the 2.4GHz and 5GHz networks.
• Reconnect manually to the 5GHz SSID.

Check Router Settings

Log in to your router's admin panel (usually via 192.168.1.1 or 192.168.0.1).

Ensure:

• 5GHz is enabled and broadcasting.
• SSID is different for 2.4GHz and 5GHz (e.g., MyWiFi_2.4G and MyWiFi_5G).
• Mode is set to 802.11ac or ax for 5GHz.
• Channel is not set to Auto; try setting a fixed channel like 36, 40, or 44.

Update or Reinstall the Wi-Fi Driver

1. Go to Device Manager > Network Adapters.
2. Right-click MediaTek MT7921 > Uninstall Device (check delete driver box if it appears).
3. Reboot your PC — Windows should reinstall the default driver.
4. OR download the latest driver from:

• HP Support Website
• OR MediaTek driver via Windows Update (search for optional updates).

Advanced Network Adapter Settings

• Go to Device Manager > Network Adapters > MediaTek MT7921 > Properties.
• Under Advanced tab, adjust the following:

1. Preferred Band: Set to 5GHz.
2. Wireless Mode or 802.11 Mode: Set to 802.11ax or Dual Band 802.11a/b/g.
3. Channel Width for 5GHz: Set to Auto or 80MHz.

Power Management Settings

Still in Device Manager > Wi-Fi adapter > Properties > Power Management tab:

• Uncheck “Allow the computer to turn off this device to save power.”

Reset Network Settings

If nothing works so far:

• Go to Settings > Network & Internet > Advanced network settings > Network reset.
• Click Reset now. Your PC will restart.

Windows Updates

Ensure Windows 11 is fully updated, including optional driver updates:

• Settings > Windows Update > Check for updates > Advanced options > Optional updates.

I hope this helps. 

Take care and have a good day.
