Welcome to HP Forums, 

This is a great place to get support, find answers and tips to your technical queries.

Appreciate all your time and efforts 

To provide you with an accurate solution, I'll need a few more details:

Are you facing this issue after an update?

Use the following steps to open the Component Tests menu and run the network test.

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 main menu, click Component Tests.

4. The Component Tests menu displays.

   Your Component Tests menu might be different, depending on the components installed on your computer.

   

Network Test - This test checks the network controller. To run this test, connect to a network with a network cable. The test will attempt to configure the network controller using DHCP and communicate with the DHCP server.

To run the test, click Network, and then click Run Once.

The Network test time is 1 minute.

Keep me posted with the test results for the further assistance.

Have a great day!

Cheers:)
