ariel.demian,  I can give you drivers to download and install, but let's first try this...  Download and run the AVG Removal Tool then restart your computer. See if you can connect. If you still cannot connect, then Start, control panel, programs and features, Zone Alarm, uninstall.  Restart your computer and try to connect.   Rick
I recently installed Windows 7 64-bit Professional and installed all drivers required on my Dell Inspiron N5010. All works perfectly except the wireless card, and when I say everything I really mean every single thing in this laptop works except wireless. It seems I cannot turn on the wireless card and the Dell PC Diagnostics is telling me that the wireless card is disconnected. I have all drivers installed and I installed them in the order it was suggested on this forum. In the device manager it tells me the driver is installed and that the device is working properly. I turned the Wifi on with the F2 button but it still doesn't work. Dell QuickSet is saying that the Wifi is turned on but the wireless card is not working. Can you please help me? Is there anything I can do?
