Broadcom BCM43142 WiFi M.2 Adapter not working properly

HP Recommended
HP Notebook - 15-ac646tx
Microsoft Windows 10 (32-bit)

My laptop name : 

HP Notebook - 15-ac646tx

Wifi adapter Broadcom BCM43142 WiFi M.2

I have to disconnect and reconnect after every 5 minutes as the wifi stops working. Also I get about 1 mbps on a 150mbps wifi connection.

Please help me to sort this out.

@AD911 Welcome to HP Community!

 

I understand that you are facing issues with wifi connectivity.

 

Here's a guided troubleshooter that will help fix this issue: Click here 
 

Try these steps: 

 

Go to Device manager > select the WIFI drivers under network adapter> Right click go to properties  > Under properties go to Power Management Tab> Uncheck  "Allow the computer to turn off this device to save power". 

 

If issue persists, continue with the below steps: 

  • If your computer has a wireless key or button on or near the keyboard and the wireless activity light is off or amber in color, then press the key or button to enable your wireless adapter. This key might be the F10 key, F12 key or labeled with a symbol of an airplane. 

  • If wireless activity comes on or the activity light turns blue, you have enabled wireless on your system. Try connecting to the Internet again. If problems persist, continue using these steps. 

Keep us posted,

I have tried all this, there is some problem with the wifi card or the driver itself. Do reply if you have any solution.

Let us perform an extensive system test on the computer, here is how you do it-

 

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second.

When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click Extensive Test.

5. Click Run once, or Loop until error.

While the test is running, the time remaining and test result for each component are

shown on the screen.

6. If a component fails a test, write down the failure ID (24-digit code) so you have it

available when you contact HP Customer Support. The information is also available in

Test Logs on the main menu.

 

Keep me posted.

Problem is with the drivers installed and not with the component.
