Realtek 8136/8168/8169 NDIS 6.20 64-bit Driver - Realtek - 7.027.0920.2010

I have problems with the wireless conection in my Desktop.

My wireless conection stopped working and now the only choice I have left is by wire. 

It looks like the computer doesn't have wireless conection.

The wireless icon dissapeared from the screen and it doesn't appear in the manager device.

Does anyone know a solution?

Thanks.

Hello @TAFranco,

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 your wireless connection has stopped working, and I would be happy to help you!

To re-establish a consistent connection between your desktop and the network, I recommend following this document on Troubleshooting Your Wireless Network and Internet Connection (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.

Additionally, I also suggest following the steps below to ensure your power management settings are not interfering with

your network connection:

1. Open DEVICE MANAGER
2. Open up NETWORK ADAPTERS
3. Right click on the WiFi Adapter for the pc and left click on PROPERTIES
4. Click on POWER MANAGEMENT at the top.
5. Remove the check mark beside : ALLOW THE COMPUTER TO TURN OFF THIS DEVICE TO SAVE POWER
6. Click OK
7. Close DEVICE MANAGER and test.

NOTE: It may also be checked under the FAMILY CONTROLLER (eg. Realtek PCIe GBE Family Controller which would be listed under the WiFi Card). If so, you could remove the check mark beside ALLOW THE COMPUTER TO TURN OFF THIS DEVICE TO SAVE POWER.

If the issue persists, I recommend following the steps below, starting with a flush of the DNS:

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, if none of the above works I would like you to try to Install Windows updates in Windows 7. I would recommend you ensure all updates are done.

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

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.

Please re-post with the results of your troubleshooting, and I look forward to your reply!

I had this same problem a month or two ago.  The wireless network adapter just disappeared one day.  It doesn't show up in device manager anymore.  I just upgraded to Windows 10 hoping that would magically fix the problem, but it didn't.  I went through all the steps you mentioned and still only show the Local Area Connection Adapter.  Could it be a hardware issue?
