Solved!

Wireless Capability is Turned Off, Wi-Fi On/OFF button Greyed Out

HP Recommended
HP Pavilion 15-p045tx Notebook
Microsoft Windows 8.1 (64-bit)

Hello,

 

I have been facing this issue for a a long time.

On Network Diagnosis, It is giving this error :

Wireless capability is turned off

 

I did not have any hardware button that can Turn Off/On wifi device on my keyboard, see below image for example :keyboard_layout.jpg

I never turned off the wifi physcal device directly or from BIOS.

Tried the "f12" Airplane Mode also, that also didn't help.

 

Anyways I have tried following things till now, nothing helped :

 

1) Reseting the HP BIOS using HP Usb Disk

2) Updating the Broadcom wireless drivers using HP Support Assistent

3) Re-installing the Broadcom Drivers

4) Installing the Realtek Drivers

5) Restroing the complete Windows 8.1 from recovery Disk.

6) Installed Linux (Ubuntu/Fedora), but in that also wi-fi is not showing.

 

 

Please guide me what can be the possible cause for this problem.

Hi

 

Normally Linux will connect to an ethernet automatically and perhaps a Wi-Fi, but the usual thing is to search out the Wi-Fi drivers and install them.

 

So if you have tried the hardware in more than 1 OS with the best drivers available then it suggests the hardware has failed.

 

I suggest trying this simple batch file in the hope it will show a defect somewhere, and perhaps the Flow Chart.

 

If in doubt please ask.

The issue seems to be with my wifi hardware chip. 

Eventualy I had to take the laptop to Service Center. The guy tried everything that I did again.

 

Finally the problem is resolved, he plugged out the wifi hardware chip, cleand its both ends a little bit using a eraser, and inserted again and voila, it got detected. He said it could be the issue of carbon lodged on chip's connecting ends.

 

Since then I have faced same issue several times, and All I do is open my laptop, plug out WiFi chip from motherboard, clean it a little and plug it again.

And It starts working like a charm.

May be it is loose or I don't know what is the exact problem.

But it still has a problem with Antenna, I recieve very low signal from my wifi, even I am within decent range of wifi router.
