One of my Dell laptop is not connecting with wifi network, once i troubleshot, then it show message to restart your WIFI router, but after restarting the router its not connecting.

Earlier, this laptop was connecting perfectly with WIFI. My Dell laptop configuration is Windows 7 OS and processor is Core i5.

I don't think the problem is related to WIFI router, because my another laptop and mobile device is connecting successfully with WIFI.

Can anyone help me on this.

What access point and which chipset has your laptop wifi ? There exist some incompatibilities. –  André Schild May 22 '13 at 7:39
    
How far away are you? Does this issue occur when close to the router? Also, is there a problem when hard wired? –  Dave May 22 '13 at 10:28
    
@DaveRook, If i used wired with modem then its connecting correctly. –  Priyank May 22 '13 at 10:36
    
And does it kick in depending on distance from router? Put the laptop next to it, reboot and see if it works please. –  Dave May 22 '13 at 10:37

Using System Restore in Windows 7, have you tried restoring to a date previous to this problem occurring? –  CharlieRB May 22 '13 at 11:40

Try to hard reset the router using a paper clip (press and hold for 60 seconds) then configure again the router

Is the system unable to even detect the Wifi Signals? If it is Able to Detect then what is the exact error code that you get when your try connecting it.

Make Sure Card is Not disabled. Try to forget Connection and Try again. re install The Drivers from dell.co.in/support
