Sponsored Links

This post will help you to download latest driver for Atheros  AR8152 PCI-E Fast Ethernet. My Dell laptop encountered a Network problem due to incompatible version of built in Atheros Network Adapter. Default driver which was shipped with the Dell laptop is not working with Windows 7 Operating System. 

If you are facing similar problem, you can compare the version of driver that you have installed with the latest version available in the vendor website. You can determine the driver version using Device Manager console. More details are in this link.

If the version of driver you have installed is incompatible, you will see a yellow exclamation mark in the Device Manager, as seen in the below picture.

Sometimes you wont be able to update driver directly through the driver update wizard. You may get the below error message:

"Windows encountered a problem installing the driver software for your device
Windows found driver software for your device but encountered an error while attempting to install it.
This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"

In this case, try to download and install latest version of device driver.Click here to download.
If this version does not work, open Vendor website and search for latest driver version. (Atheros is now subsidiary of Qualcomm)
