Wifi Not Working After BIOS Update

[Marius_Ciobanu]

Hi,

I have updated the BIOS to the latest version after installing a fresh copy of Windows 10 and the wifi adaptor cannot be enabled. When pressed, the wifi enabling button turns from amber to white, but the wifi adaptor still does not work. I have checked in device manager and everything is OK. I have used Windows troubleshooting and HP troubleshooting and the results is the same: I am told to press the wifi button as it  detects that the wifi is disabled - all this while the button is already pressed showing that the wifi is enabled (white colour instead of amber). Is there any way to revert to the previous version of BIOS? Are there any other solutions I could try?

The wifi worked fine before I updated BIOS.

Thank you very much for your support!

Hi

Initially try the troubleshooting, then the button driver and then the .BAT

Hi,

The problem persists. I have run the LBB.bat file as an administrator and the only difference is that now the wifi button remains amber and no longer turns white (active). When I press the button, it indicates Airplane Mode on or off.

Are there other ways to fix this?

Thank you very much for your support!

This is the screenshot I am getting.

Hi

Not really.

But the results (actually copy and paste is my preference)  drop into notepad and edit out the personal bits.

I will try to read thru the listings and answer again.

I realise we are posting simultaneously and I may seem to be stating something stupid, that you have already said.

Hi,

Thank you for your quick response. I will edit out the personal details.

We both have the same driver installed.

Both cards are there.

Now I get egg on my face...

C:\>getmac

Physical Address Transport Name
=================== ==========================================================
27 Media disconnected       Me WiFi
28 \Device\Tcpip_{65}

C:\>getmac

Physical Address Transport Name
=================== ==========================================================
27 \Device\Tcpip_{F9}
28 Media disconnected

Plug in Ethernet no WiFi, pull out ethernet WiFi.

Active BlueTooth can take precedence over WiFi on some basic cards.

ping 127.0.0.1 should loopback on the WiFi adapter, if/when it's the only device in use.

Thank you for your message! 

Maybe you are misunderstanding what I want to say. You have below several screenshots which show that no matter what I do the WIFI does not work. Below is the airplane with no WIFI:

Below is the "enabled" WIFI, after I press on the wifi button (although it remains amber):

If I click on the WIFI option, it greys out:

If I try to enable it in some other way, it still does not work: 

Everything is enabled in device manager:

Everything is enabled and, according to the device manager, works OK.

I have also included a video which shows that, while connected to the Ethernet, when I press the button it will switch between the ethernet and airplane mode ( WIFI will not enable). 

I could not upload the video on the website directly as there is an error on it (the dialog box is overlapping with another text). The link to view the video is: https://we.tl/t-60MsVr1wwU
