Maybe this will help Open up your device mgr.
In Devise Mgr -If everything is properly detected you'll see all +'s next to each of the device categories with no "Other devices" listed as shown in the example. However, when problems do occur you'll be presented with one or more of the below errors.

When a device has a yellow circle with an exclamation mark or found under "Other devices" this is an indication that the device is conflicting with another hardware device or the drivers for the device are not installed properly.

Double-clicking and opening the device with the error will present you with an error code.

What to do

Remove all devices with exclamation mark and any "Other devices" from Device Manager by highlighting them and pressing the delete key on the keyboard. Once they've all been removed reboot the computer and allow Windows to re-detect the devices.

If after rebooting the computer the Device Manager remains the same Windows is not installing the devices because it lacks the proper driver support. You'll need to download the latest drivers for that device.

No wireless adapter
Hi,

Have you check the wireless card under the Device Manager?

Start->Control Panel->Device Manager

Under Device Manager look for Network Adapter there will be sub folders under network adapter look for the wireless device. If its not showing it means that the Device is not working. If you want to make sure try to reinstall the Operating System and after that check again the Device Manager.

Wireless networking hardware not functioning properly.
Check on Device Manager if it is working properly

Right-click My Computer-Properties-Hardware-Device Manager
Click on the plus sign beside Network Adapter and double-click your wireless card.
Check on the device status if it says it's working properly.
Try to disable-enable the adapter by right-clicking on it under the device manager window.
If it has a question mark, it is most likely driver issues so contact your wireless card manufacturer or PC manufacturer if the wireless card is built in.

Wireless connection disapeared from computer
Hello!

I am not sure exactly where you are checking for Wireless connections.

Anyhow, now a days we are hearing many Wireless adapter missing from Device manager issues.

Please get back to us with the Brand name of your laptop, OS installed.

Also check in Device manager for Wireless adapter.

Please follow these steps to open Device Manager:

1. Right Click on 'My Computer' icon on Desktop and choose Properties.
2. The System properties Window opens.
3. Click Hardware tab and then click the Device Manager button.


Expand + Network adapter and check if the Wireless adapter is listed there or not.

If it is not listed there, then the issue is with the Wireless adapter itself.

This is most comon issue in HP COMPAQ notebooks.

if you are not aware of the Wireless adapter under + Network adapters in Device manager, then get back to us with the complete information under + Network adapter.

So thatI can help you in better way
