Wifi gone on HP DV6000 Laptop

I have HP DV6000 Laptop. Few months ago its Wifi stopped working suddenly. Even Device Manager was not showing it. I was using Vista that time. I thought it is some Virus related issue. I reinstalled Vista but no luck.

I installed XP still no luck. After that I install Ubuntu still no success. No operating system even displays. Then I purchased a USB Wifi which works good.

But I want the orignal wifi back. It works sometimes (like once a month). I have noticed it works when my laptop is hot. One day I mistakenly put my laptop in the bag without shutting it down. When I took it out the laptop was quite hot but the Wifi was working.

I would be thankful if someone helps in fixing this issue.

hello

strange issue. I hope for you that wifi is not inside the motherboard. sometimes there is a mini-pci card accessible usually by the bottom.
you can find one for less than 20 dollars on ebay, try to change it and you'll see.

You could also try taking out he wifi card from the bottem of the laptop and reseat it back in the laptop.

But i do agree with greg vander it could be going defective and need to be replceed.

Sounds like the internal WiFi card is faulty, you should replace it, as greg says you can purchase a new one if your laptop uses a mini-pc card for it

I have already tried replacing the Wifi card but no luck. This shows it is not Wifi's issue.

have you tried removing the drivers, shut down remover the wifi card, boot up then shut down
install the card boot up and install drivers, test the card.

Your laptop probably has a physical button somewhere around the edge to enable and disable the card. This would explain why its not showing up in device manager and why it worked when you pulled it out of your bag. Some of the buttons slide from one side to the other

did you try switching it to the other side?

Yes I am familiar with this switch. It also has a light which remains Orange in my case. But when it was working it used to be Blue.

I have tried to both the sides.

There is your problem. You need to slide it to the right. The orange light on that model means you have turned the Wireless card off. It needs to be pushed all the way to the right. If it does not come on right away, switch it to the right and restart. Mine slides out REALLY easy as well (I have a DV9000). When I got home I pulled my laptop out of my bag and it slid it to the off position. It's very annoying.

It is already on right side. No luck. It seems to be some hardware issue with motherboard etc.

There is a physical switch underneath that button, I'm not sure what your technical ability is but if you open your laptop up the switch may have either slid out from under the cover or be broken. Does it click into place when pushed to the right?

just a question to be sure.
are the antennas not broken ?. you know it's two cables connected to the wifi card. they usuakky go through the laptop and the screen.

a24hrpcCommented:
Greg- If the anteanna was broken wouldn't the wireless card be able to be turned on? I would think you just would not get any signal.

Systemsautomation: When you crack open the laptop I would also check to see if the card is seated properly.

greg_vanderCommented:
yes, in fact -sorry for misunderstood- antenna is just for the signal.

perhaps the card make a conflict with an other perpheral. did you try do extract all possible and test like that.
you should ask HP as well to see if it's not a motherboard problem (bad serial, ....)

I believe that since what you told me about the switch. Is it under warranty? You could try to swap it.

It is under warranty till August but the problem is I live in Pakistan and my uncle brought this for me from US. The only way I can avail warranty is to send it back to US but this is not possible for me.
