Qualcomm atheros 802.11 a/b/g/n dualband wireless network module is dying

[inter9115]

I have an issue with  Qualcomm atheros 802.11 a/b/g/n dualband wireless network module - after a couple of hours of works my computer starts dropping connection for 5-30 seconds (I have installed monitoring software). It is not router or modem issue since wi-fi on my laptop works fine. I also tried to turn off my Norton Insternet Security, but it didn't fix the issue. Once I connected my pc to router though eithernet all connection issues gone.

Question: what is the good replalcement for  qualcomm atheros 802.11 a/b/g/n dualband wireless network module? I can't figure out what model it is and  qualcom seems to offer different set of products now.

Hello @inter9115,

Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.

I have read your post on how the dualband wireless network drops the connection between 5-30 seconds, and I would be happy to help you!

To better assist you, I will need to:

1. The Product and Model Number of your desktop computer.
2. The version of Windows you have installed on your computer.
3. If your computer has completed all of its important Windows Updates.
4. If you have updated your HP drivers using the HP Support Assistant.
5. If this is an on-going, or recent issue. 

Please re-post with the necessary information, this way I will be able to research this further for you. I look forward to your reply!

Thanks for reply

1. HP Pavilion Elite e9280t Desktop
2. Windows 7 Professional Service Pack 1 64 bit
3. Windows is updated.
   
4. Driver for the network module is up to date.
5. I have this issue for the past 3 weeks. Every day after my machine is on for a few hours I start dropping connection. Connecting router through eithernet cable  (instead of wi fi) fixes the issue.

Hello again inter9115,

It is good to hear from you again!

To re-establish a consistent connection between your notebook and the network, I recommend following this document on Troubleshooting Wireless Network and Internet (Windows 7). This should help run a diagnostic on your system using the Network and Internet Troubleshooter, as well as steps to keep your system on the wireless network. 

The next step I suggest is to flush your DNS. You can do this by following the steps I have set out below:

Step 1. Click the Start button
Step 2. In the search box, type "Command Prompt"
Step 3. Right-click Command Prompt

Step 4. Click Run as administrator
Step 5. At the command prompt, type "ipconfig /flushdns"

Was this successful? If not, I would like you to  reset the TCP/IP stack. To do this follow the next set of steps I have set out below:

Step 1. Click the Start button
Step 2. In the search box, type "Command Prompt"
Step 3. Right-click Command Prompt

Step 4. Click Run as administrator
Step 5. Type "netsh winsock reset catalog" and hit Enter
Step 6. Type "netsh int ip reset reset.log" and hit Enter
Step 7. Restart your computer

Next I would like you to try the next set of steps I have set out for you below:

Step 1. Click the Start button
Step 2. In the search box, type "Windows Explorer"

Step 3. Click on Windows Explorer

Step 4. In the Address bar at the top try to stream a video or download Google Chrome

If you are still not able to connect to your network, you will need to remove and re-install the WiFi adapter drivers on your notebook. To do this, I recommend removing the drivers in Programs and Features and the Device Manager. Once the old software is removed, please restart your computer. The drivers for your wireless network adapter can be downloaded an installed by following this document on Downloading or Updating Software and Drivers for HP Computers. 

Next, if nothing has worked we are going to try using Using Microsoft System Restore (Windows 7) to restore your computer back to a point in time before this issue arose. This will not affect any personal files you have on your computer, but it will affect any settings you have changed or applications you have installed since the time you go back to. These will have to be re-done once we are finished.

Lastly, If we still have the issue we are at the point where we need to use the HP Support document: Backing Up Your Files (Windows 7) to back up your personal files. Once we have done this successfully I would like you to review and follow the steps set out in the HP Support document: Performing an HP System Recovery (Windows 7), which will walk you through restoring your computer back to factory.

***NOTE: This will destroy everything on your computer so make sure you have backed up everything you wish to keep.

Thanks. I tried resetting DNS and flashing TCP/IP stack first - didn't work.

I also tried uninstall and instal again module driver - worked fine for a few hours, but after the restart  the issue was back.

I will not try reverting back or recovering windows since the module doesn't worse it.

My question is not how to fix it, but what model to use to replace it.
