Hello @bhanuadvance

Thank you for posting on the Intel® communities.

In order to review this further, could you please confirm the following details?

1. Are you having issues with Wi-Fi only or with Bluetooth too (both)?
2. When did the behavior start to happen? Did the system work fine before at any time? Is this a new computer? Please provide details.
3. Do you remember if this issue happened after a new Windows update or Wireless/Bluetooth driver update?
4. Is the Intel® Wireless-AC 9462 the original wireless adapter that came pre-installed in your system or did you integrate it on the computer?
5. When you said "drivers get corrupted (...), drivers stop working", what is the exact behavior? Do they show an error message? Perhaps on the Windows notification area or in Device Manager >> Network Adapters >> Intel® Wireless Adapter >> Properties >> General tab?

Also, please run the Intel® System Support Utility (Intel® SSU) to gather more details about the system:

• Download the Intel® SSU and save the application on your computer
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click Next and click Save.
• Once you have saved the file (.txt file), please attach it to your reply.

To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.

Dear Andrew ,

Thanks for your response and support. Please find the below answers and SSU file attached along with this.

1. Are you having issues with Wi-Fi only or with Bluetooth too (both)?   Only wifi .
2. When did the behavior start to happen? Did the system work fine before at any time? Is this a new computer? Please provide details.       It was the issue from beginning. connected to dell support also but not resolved. 
3. Do you remember if this issue happened after a new Windows update or Wireless/Bluetooth driver update?  I updated with the thought that it will resolve my issues with WIFI but not happened so, the issue was before updates also. 
4. Is the Intel® Wireless-AC 9462 the original wireless adapter that came pre-installed in your system or did you integrate it on the computer?  Came pre installed with the laptop.

When you said "drivers get corrupted (...), drivers stop working", what is the exact behavior? Do they show an error message? Perhaps on the Windows notification area or in Device Manager >> Network Adapters >> Intel® Wireless Adapter >> Properties >> General tab?  When i check the device manage network adaptors, yellow exclamation sign observed. Properties not able to check right now because it is working now. whenever i observed it will share the same again.

Thanking you , 

Best Regards,

Hello bhanuadvance

Thank you for your response.

We understand that when the issue happens, a yellow exclamation sign is observed but for now, the wireless adapter is working. However, if the issue happens again, we recommend the suggestions below.

A yellow exclamation sign usually relates to an error code in Device Manager, some examples are Code 10, 28, 43, or 45. These errors in Device Manager for Bluetooth or Wireless (Wi-Fi) Devices can be caused by many different issues and they are considered a generic message indicating an unspecified problem.

If the disconnection issue happens again and/or if you see any of those error codes, please follow these steps:

A- As a first approach, we recommend performing a Cold reboot of the system after reinstalling the driver. This refers to fully shutting down the device and removing all sources of power, including batteries if applicable, then repowering.

We recommend you install the drivers customized for your specific system model and provided by your Original Equipment Manufacturer (OEM) DELL*. You can download the driver from this link.

B- If the issue persists, please proceed with the following steps:

1- Make sure the operating system (OS) is up to date and install any pending Windows* Updates. Please refer to this link for further instructions: Update Windows*.

You may also check with Microsoft* Support for additional guidance.

2- Perform a clean installation of drivers for both components Bluetooth and Wireless using the customized drivers provided by the computer manufacturer (OEM) DELL*:

• Intel WIFI Driver 22.150.1.1, A41.
• Bluetooth Driver Version 22.150.0.6, A36.
• Important: Download the drivers before uninstalling the driver if you are following the instructions for a clean installation process.

Follow the steps in these articles for installation instructions:

• How to Perform a Clean Installation of Bluetooth Drivers
• Clean Installation of Wireless Drivers                      
• Note: During the process, after uninstalling the current drivers and before reinstalling the drivers, you may clear out your temporary files: Press the Windows* Key + R to open the run box. Type Cleanmgr.exe and press OK. Here you will need to make sure Temporary Files are checked, you may uncheck everything else, then press OK. Reboot your computer and proceed to install the drivers.
• We recommend installing the Bluetooth driver first, followed by the wireless driver.
• After completing the installation of both drivers, please reboot the PC.

If the issue persists, please repeat the clean installation process using the generic drivers from Intel:

• Intel® Wireless Bluetooth Driver Version 22.150.0 (Latest).
• Windows® 10 and Windows 11* Wi-Fi Driver Version 22.150.0 (Latest).

3- Also, it seems there is a new BIOS updates available for the system, the latest is: Version 1.17.0*.

We recommended checking with DELL* Support to see if they recommend updating the BIOS in case it may help with this behavior. They may also assist you with the BIOS update instructions.

C- If the issue still persists and the system shows the error messages and/or experiences disconnection errors, our recommendation is to contact DELL* Support again for additional support, especially considering the behavior is happening since the beginning, the system might also require also a physical inspection.

Hello bhanuadvance

Thank you for the screenshot from Device Manager.

We can see that the error message references Error Code 43. For this type of error, the steps suggested in our previous post are recommended for this scenario.

Just to make sure, is the wireless connection still working fine, or have you experienced the issue again after our last post (yesterday)? If the issue occurred again, were you able to try the suggestions?

Best regards,
