computer disconnects from internet

[Marti902]

My computer disconnects from the internet every 5 mins then reconnects.  Realtek RTL8852BE WiFi 6 802.11ax PCIe Adapter. I have done a complete re-install and that didn't solve the issue.

Hi @Marti902,

Welcome to the HP Support Community.
 

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

I understand how frustrating it is when your HP 17t-cn300 laptop keeps disconnecting from Wi-Fi every few minutes, especially after a full reinstall didn’t help. Let’s walk through the most effective steps to fix this.
 

Step 1: Update to the Latest Realtek Driver

HP released a driver update that specifically addresses issues with Wi-Fi instability, auto-reboots, and access point detection failures.

• Download the latest driver here: 👉 support.hp.com/soar-attachment/905/col113634-ob-296690-1-ob-296690-1_sp142005_releasedoc.html

Instructions:

1. Download the .exe file.
2. Run it and follow the on-screen instructions.
3. Restart your laptop after installation.

Step 2: Disable Power Saving for Wi-Fi Adapter

1. Press Windows + X → choose Device Manager.
2. Expand Network Adapters → right-click Realtek RTL8852BE → Properties.
3. Go to the Power Management tab.
4. Uncheck “Allow the computer to turn off this device to save power”.
5. Click OK.

Step 3: Run HP Network Diagnostics

Use HP’s built-in tool to scan and fix network issues:

• Download and run HP Support Assistant: 👉 Fix HP Computer or Laptop Networking Problems | HP® Support
• Open the app → select your device → run Network Check under Troubleshooting and Fixes.

Step 4: Reset Network Settings (Optional)

If the issue persists:

1. Go to Settings → Network & Internet → Advanced Network Settings → Network Reset.
2. Restart your laptop and reconnect to Wi-Fi.

I hope this helps.

Take care and have an amazing day!
