Blue WLAN light will not come on, "this computer does not have a wireless network adapter installed" Help!

I woke up yesterday morning and suddenly my laptop will not pick up my (or any) routers. The blue light on the front of it will not come on, even though the switch is set to on. When I click "Diagnose why windows can't find any networks", I get the message "this computer does not have a wireless network adapter installed". Well it was working 24 hours ago.

I've restored my laptop to its factory shipped condition and updated it from hp update and windows update, but it still does not work. I cant even open the hp wireless assistant from control panel, when I click on it, nothing happens!

The laptop is a HP G6000, I have 2 of them and the other is working fine. Under the network tree in device manager, the working laptop looks like this >>



And the one that is not working looks like this >>




As you can see, the WLAN thing that I need, is not there. I have no idea why my laptop would suddenly do this. I've been looking for a solution all day and found nothing. From reading some stuff on the hp site it looks as though ALL of my wireless devices are turned off. apparently they get turned on at the factory and they should not turn off. I have no idea how to turn them back on if my computer is not even picking them up. Someone recommended me to "flash the BIOS", should I do this and what does it mean?

I dont think there is a problem with my modem or router because my pc, other laptop and ps3 are all connected to the internet just fine. Any help would be greatly appreciated.

 

this will occur if the wireless card has become dislodged or it has failed.
I believe the wlan card is in the same location as the memory modules on the bottom of the notebook.

Open, remove, reseat

 

done this, but still nothing.

 

Since you have identical laptops, I wonder what would happen if you took the wireless card from the working one and put it in the non-working one.

Would certainly tell you if the card were functional.

 

Ive now swapped both cards from both laptops and it still does not work. The one that used to work still works, so its not the card.

 

More info, when I right click the network icon in the tray and click "diagnose and repair" it says - A cable is not plugged into the network adapter "Local area connection".

The problem seems to be with the network adapter, is that the same thing as the network card? It looks like ALL of my wireless components are turned off, anyone know how to turn hem back on again?

 

There is a button on the left hand side, front of your laptop than can disable wireless. As far as I know, you do not have a Function key combination to do it.

 

yeah that switch is switched on.

 

Sounds like a bad motherboard to me---one more thing, sometimes, wireless can be switched off in BIOS (sometimes called system setup, accessible by pressing F1, F2 F12 or DEL when system boots)

 

Its enabled in the bios. I've asked another person about this and they also said its probably the motherboard. Is this bad? Will hp fix it?

 

If it is under warranty, they will. HP recently extended the warranty for a whole slew of laptops where the wireless adapter going was the first sign of the motherboard itself dying completely--I checked the list, though, and your's is not one of them.

 

I've had EXACTLY the same problem.

I did a complete restore and installed Windows updates and the light turned blue.

Now it's orange again - No idea why. Feel like throwing the thing.

 

That has nothing to do with your wireless connection - that's basically just telling you in a very obtuse way that your wired ethernet connection is not plugged in.

 

I have been having the same problem. I found out that it is a motherboard problem and that H.P. launched a service enhancement program to replace failed motherboards. Here is the link:

If the wifi appears in Device Manager but the radio doesn't want to come on, then can cellophane tape W_Disable pin 20 on the wifi card to enable the radio permanently.

Though that is not the problem here. Since your wifi doesn't appear in Device Manager, yet works in another system, if would indicate your mPCIe port itself has some fault. A hardware repair is in order.

 

Then plug it in and see what happens?

Incidentally, it might be helpful if you mentioned what you did antecedent to your malfunction. Think! Did you do anything out of the ordinary?
