WiFi Broadcom BCM 43142 randomly drops

HP Envy 15t
Microsoft Windows 10 (64-bit)

I have an Envy 15t purchased in January 2016. Everything works except the WiFi, it keeps dropping.

 

I have restored it, updated it, and updated the driver with no change in the operation.

 

I have another laptop an Envy dv6 with a different wireless card and it works fine.

 

This PC has the Broadcom BCM 43142.

 

Anyone have solution or do I need to replace the PC?

WiFi Broadcom BCM 43142 randomly drops

Hello @BobB77,

 

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 you are having issues with the WiFi, and wanted to assist you!

 

To start, can you provide me with the Product Number of the notebook?  Here is a link you can use that will help you find your Model and Product Number:

HP Customer Support - Products

 

In the meantime, try reviewing the following steps, offered by community member 

@Great-Deku-Tree:

 

Here is a list of steps that commonly resolve issues with wireless connectivity.

 

First, we have a step by step guide to walk you through the troubleshooting process here: 
Troubleshooting Your Wireless Network and Internet Connection

 

A second option, is to try these steps:
Powercycle the network:
1. Shut down your notebook.
2. Unplug the power to your router.
3. Unplug the power to your modem.
4. Wait at least 45 seconds.
5. Plug in the modem, and wait for it to come back online.
6. Plug in the router, and wait for it to come back online.
7. Turn on your notebook, and test your connection.

Disable the Power Off option for the adapter:
1. Open Device Manager. (Win Key+R > type devmgmt.msc > OK)
2. Expand the Network adapters.
3. Right click on the Ethernet/Wireless Adapter and click Properties.
4. Click the Power Management tab.
5. Remove the check mark beside Allow the computer to turn off this device to save power.
6. Click OK.
7. Test.

Reset the TCP/IP settings on your PC:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.
4. Restart your PC and test.

It may also help to reset the winsock catalogue:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh winsock reset" without quotes, and press enter.
4. Restart your PC and test.

Reinstall the network adapter drivers:
1. Download the drivers from here but do not run them yet.
2. Go to your start screen/menu and type Device Manager.
3. Expand Network adapters.
4. Right click on the wireless adapter and choose Uninstall.
5. Run the downloaded drivers from step 1.
6. Restart your PC and test.

Test an ethernet connection:
Self explanatory. Test if the issue persists on a wired connection to rule out the wireless adapter hardware so troubleshooting can be directed towards the right areas.

Test another connection:
Many people rule out their home network as an issue if another device is working on the same network. Networking is not that simple. Each device interacts differently with your router or modem and it is impossible to rule out settings in that device until the notebook has been tested on another network.

If those three steps do not resolve the issue, try this document published by Microsoft for networking issues: Wired and wireless network problems. You can change the operating system with the dropdown in the upper-right corner of the document.
