wifi is not working after installing windows 7

[Paul_Tikkanen]

I would reinstall W10 and see if the wifi works again.

If it doesn't then for some reason, the wifi card has died on you, and needs to be replaced.

By all counts, the wifi should be working just fine.  It is as if the radio is turned off.

Should you have to resort to replacing the wifi card, you may as well upgrade it.

This model should work if there are two antennas connected to the Ralink wifi card in there now.

There should be.

Intel Dual Band Wireless-AC 7260 802.11 ac 2x2 WiFi + BT 4.0    HP Part # 710661-001

cards are readily available on eBay or Amazon, and don't cost very much at all.

Do your search by the HP part number, not by the model number of the wireless card.

Here is the link to the service manual.  The wifi card R & R procedures can be found in chapter 5.

It's a relatively easy job to do on your model.

Okay I am going to install windows 10 on another partition. Let you know in sometime

[saudfarooqui]

Okay dear, I've installed win 10, and wifi working absolutely fine.

[saudfarooqui]

What next? I think this assures that my card doesn't have any problem, the problem is somewhere else. What would you suggest now?

[Paul_Tikkanen]

OK.

What I would do then is to reinstall W7, and use the Wifi and bluetooth drivers I posted.

The first driver you should install is the Intel chipset installation utility, followed by the Intel and AMD graphics drivers, then the audio.

Restart the PC after you install each of those drivers.

[saudfarooqui]

Why are you making it sequential? Why can't I install randomly?

[Paul_Tikkanen]

There is a recommended order in place for years for installing drivers.

Chipset, grapics, audio, ethernet.  Then you can install the rest in any order you want.

This prevents issues like you are now experiencing.

At the very least install the Intel chipset installation utility first and restart the PC before installing the wifi driver.

The chipset installation utility installs the motherboard drivers and that may impact the wifi card operating if that driver is not installed first.

W10 has many of those drivers already included.

If you don't mind, could you please provide the links for the drivers in series. It is really hard for me to decide which are the right one from the list on website 

[Paul_Tikkanen]

You already have the wifi and bluetooth.

Chipset:  Install first and restart.
