Multiple posts don't get your question answered any faster. Click Start --> All Programs and then look for either Dell Wireless or Intel wireles and start the wireless network program. Click on Place Icon in System Tray.

Thank u anyway for the reply. Managed to follow your advice below except for the part where u say "click on Place icon on system tray" I dont see that option.
