How to get the wireless back on your HP Pavillion DV4 Entertainment PC - Older model

[dlabonte45]

I was able to get my wireless back working by plugging in an ethernet cable to the laptop, as soon as I plugged into the ethernet it allowed me to turn on wireless networking WLAN using the wireless assistant. before that it was greyed out and I could not connect.

@dlabonte45 Have you run a wireless card test on your device to identify if this is either a hardware or a software malfunction?

If not, let's start with that:

• Turn the computer On and keep tapping F2 repeatedly on startup to enter system diagnostics. 
• Select the component test and run a wireless test on your computer.

  • (By the end of this article all the issues should be resolved)

If the test fails or does not detect the wireless card, this could be a hardware malfunction, please revert to me with the failure ID,

However, if the tests pass, restart your computer, then visit the HP website and use the product number of your device to download and install the wireless adapter from the list under the Windows OS you select.

• If the issue persists, you may want to create a backup of all your important data into an external storage device and perform a system reset:
• Refer to this HP Article for assistance.
