Broadcom BCM43142 802.11 bgn Wi-Fi Adapter Issues.

[Shonsey]

I have an HP Envy 700 PC Series with a Broadcom BCM43142 802.11 bgn Wi-Fi Adapter. I got this pc back in March. Often, the wifi dropped, but back then it was where it was not an issue and it rarely happened. Recently, though, my adaptor has been dropping my internet connection constantly. I've run the HP support drive update, I've used HP Network Check, I've tried pretty much anything I could find to fix it, and the problem still remains. Is there a way to fix this without having to get a new adaptor?

Hello @Shonsey,

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 understand that your desktop computer is not able to connect to your wireless network, and I would be happy to assist you in this matter!

To re-establish a consistent connection between your desktop and the network, I recommend following this document on Troubleshooting Wireless Network and Internet (Windows 😎. 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 /release" and press Enter

Step 6. Type in the command "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 8. 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

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 😎 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 😎 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 😎, 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.

Product Name: HP Pavilion 17-f010na 17.3-inch Laptop

Operating System: Microsoft Windows 8.1 (64-bit)

The wi-fi disconnects continuously. I receive the following message:

The Broadcom BCM43142 802. 11bgn Wi-Fi Adapter is experiencing drive - or hardware problems.

I made every possible update for both Windows and the Wi-fi driver (even from the manufacturer's web-page)

Moreover, my laptop was kept for the last three days by the Technical Service of John Lewis and I received it today. The laptop faces the same problem, plus they updated it to Windows 10. I am completely frustrated.

I have lost a lot of time, I cannot work, obviously the problem hasn't been solved and I have regretted for spending money to buy an HP product.
