Hi, shehel123, I'm gonna see if I can give you a hand. First off, what OS are you using? Just in case it's Windows 8, here's a document on troubleshooting WiFi connections with Windows 8. It's appropriately titled Troubleshooting Wireless Network and Internet (Windows 😎. If that helps, great! If not, let me know what your OS is and I'll see if I can give you better info.

Thanks!

Sorry.Windows 7 it is

[Fenian_Frank]

No problem. So this document will probably work better for you. Give your WiFi connection a troubleshooting run-through with this information and if THAT doesn't work, again, I'll see what else I can do! Good luck. HP and Compaq Desktop PCs - Troubleshooting Your Wireless Network (Windows 7)

Hi:

Is there a Network Controller device listed under an Other Devices category in the device manager?

If so, then that is the wireless card in need of a driver.

If you see that device, please do the following and I will post the link to the driver it needs...

Go to the device manager, find the Other Devices category, and click on the Network Controller needing drivers.

Then click on the Details tab at the top of the network controller window.

Now you see a Property drop down list and it is defaulted to Device Description.

Drop down on that and select the second item on the list (Hardware ID's).

Post the top string of characters that begin with PCI\VEN

If you don't see the model of the wireless card listed under the network adapters category in the device manager and you don't see a Network Controller device, then most likely the wireless card has died on you and needs to be replaced.

The top string goes like
PCI\VEN_14E4&DEV_4727&SUBSYS_1795103C&REV_01
