Qualcomm Atheros QCA61x4A is the most commonly used network adapter. If this adapter is not working well on your Windows 11, it means your network adapter, specifically your Wi-Fi adapter, is not working properly. But don’t fear, it’s easy to resolve.

How to fix the Qualcomm Atheros QCA61x4A driver issue?

  1. Re-enable the Qualcomm Atheros QCA61x4A wireless adapter
  2. Update the Qualcomm Atheros QCA61x4A driver
  3. Roll back the Qualcomm Atheros QCA61x4A driver

Before we go through the above tips, doing a reboot to your computer would be suggested, as it flushes the buffer and closes the background applications which might interfere with your system. Once done, continue with the steps below.

1. Re-enable the Qualcomm Atheros QCA61x4A wireless adapter

Whether your PC is suddenly disconnected from the network or your wireless adapter is unable to detect any wireless networks, here’s what you can do:

  1. On your keyboard, press the Windows logo key and X together and select Device Manager.
  2. Double-click to expand the category Network adapters, right-click Qualcomm Atheros QCA61x4A Wireless Network Adapter, and then select Disable device.
  3. Click Yes to confirm.
  4. Open Device Manager and right-click Qualcomm Atheros QCA61x4A Wireless Network Adapter again. Now, select Enable device.

You should now be able to use your Qualcomm wireless network adapter again. You can check whether the Internet is working properly by opening a web browser. Alternatively, you may try the next fix if that hasn’t worked.

2. Update the Qualcomm Atheros QCA61x4A driver

If you still can’t connect to the Internet, one of the first things you should do is to update your Qualcomm adapter driver, as it may be corrupt, outdated, or incompatible with your operating system.

To update your Qualcomm adapter driver, here’s what you can do (please note that the following screenshots are taken on Windows 11, but the instructions work on Windows 10 as well):

  1. On your keyboard, press the Windows key and X at the same time, select Device Manager.
  2. Double-click to expand the category Network adapters. Then right-click your Qualcomm Atheros QCA61x4A Wireless Network Adapter and click Update driver (the name of the device can be different on your computer).
  3. Then click Search automatically for updated driver software.
  4. Wait for Windows to find the latest driver available for you.
  5. When the driver update is done, restart your computer for the change to take effect.
  6. Then check and see if the problem is fixed.

  1. On your keyboard, press the Windows logo key and X together and select Device Manager.
  2. Double-click to expand the category Network adapters, double-click your Qualcomm Atheros QCA61x4A Wireless Network Adapter and switch to the Driver tab from the top menu. Then, click Roll Back Driver.
