HP Laptop will not connect to 5Ghz Wifi

[theboykeef]

The laptop has stopped connecting to the 5ghz wifi. Connects to the 2.4Ghz without issue. Other devices can connect to 5Ghz so the issue is with the laptop. The 5Ghz wifi is viewable on the list of available networks but when I try to conect I get the message 'Unable to connect to network'.

Wireless adapter is Realtek RTL8852BE-VS Wifi 6 802.11ax PCIe Adapter.

Can't seem to find a solution. Anyone able to help?

Thanks.

Hi @theboykeef,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

I completely understand how frustrating it must be when your laptop suddenly stops connecting to the 5GHz network, especially when other devices have no issues. Since your laptop can see the network but fails to connect, let’s go through some troubleshooting steps to resolve this:

1. Restart Everything

• Restart your laptop and try reconnecting.
• Power cycle your router (unplug it for 30 seconds, then plug it back in).

2. Forget and Reconnect to the 5GHz Network

• Go to Settings > Network & Internet > Wi-Fi > Manage known networks.
• Select your 5GHz network, click Forget, then reconnect by entering the password.

3. Check Wireless Adapter Settings

• Press Win + X and select Device Manager.
• Expand Network Adapters, right-click Realtek RTL8852BE-VS, and select Properties.
• Under the Advanced tab, check for a setting related to Preferred Band and set it to 5GHz if available.

4. Update or Roll Back the Wi-Fi Driver

• In Device Manager, right-click the Wi-Fi adapter and choose Update driver → Search automatically.
• If the issue started after an update, select Roll Back Driver (if available).
• You can also download the latest driver from HP’s support website or Realtek’s official site.

5. Check Router Settings

• Log into your router’s admin page and ensure:
  • The 5GHz band is enabled.
  • The Wi-Fi channel is set to 36, 40, 44, or 48 (some adapters struggle with DFS channels).
  • The security type is WPA2 or WPA3 (avoid WEP).

6. Run Windows Network Troubleshooter

• Go to Settings > System > Troubleshoot > Other troubleshooters.
• Run Internet Connections and Network Adapter troubleshooters.

7. Reset Network Settings (if nothing works)

• Go to Settings > Network & Internet > Advanced network settings > Network reset.
• Click Reset now (this will remove all saved networks, so you’ll need to reconnect).

Try these steps and let me know if the issue persists!

I hope this helps.

Take care and have a good day.
