talha khan,

Places to look to see if your Connection is enabled

Hit the Windows key and the X Keys at the same time or start, control panel, windows mobility center

Click on the little antenna in the Radio Control Options.

You should then see...

Make sure the boxes are checked.

Rick

Thanks Ravi Chandra for your quick reply .. I did it all but nothing changed , it is same as it was .

Here is the picture of my device manager

I have read in other post that the order in which all the drivers are installed can also cause some problem .. I didn't know that and not followed any order .

Thanks for considering my problem Rick , I didnt have Radio option in my mobility center .

This is my mobility center.

I have installed Dell Quickset and got Radio control in windows mobility center , both WLAN and WIFI options are checked .

talha khan,

So you recently reinstalled/install the operating system, correct?

Rick

Ok I am instaling all the drivers in correct order ..

I have installed all the drivers in the given order but nothing changed .. 1 more thing the driver mentioned in first place system utilities said it was not compatible with the windows or system .

talha khan,

Rick

talha khan,

I did not see any Dell Notebook System Utility for this system. You started with the chipset drivers then followed the list.

Places to look to see if your Connection is enabled

Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.

Click on advanced. Look for Antenna Diversity. Chaneg the Antenna Diversity from Auto to Aux.

I went to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.

talha khan,

Insert the Dell Drivers disk that came with your system. Look and see if the Dell Notebook System Utility is there. If yes, then install that version and also install the chipset drivers. Then install the network adapters

Rick

talha khan,

Did you install Dell Quickset?

Rick

Dell Notebook System Utility is not listed in recommended drivers but when I optional and tried to install it says incompatible with your system/windows

This setting also doesn't work for me .
