1350 wireless network card radio DISABLED

I'm new to these forums and to also setting up a wireless network, so please bear with me.  I have a new dell inspiron 5150 w/ a 1350 wireless network card.  Also, I've got a D-link 624 router.  Until last week, it all worked perfectly.  Then, as i was surfing the web, i lost my connection.  All the lights on my router are blinking (except the status light which d-link support says is ok) and the wired connectivity works just fine.  I noticed in the taskbar that the signal strength bars and the wirless network icon are both "x"'ed out.  I tried right clicking and to enable the radio....didn't work.  I tried fn-f2, and although a pretty radio tower picture toggles between off and on, the radio is still disabled.  Also, under those settings, it is unable to find a network.  I've tried un-installing the network card and re-installing and have spent hours on tech-support.  It says the device is working properly under device manager, but the RADIO IS DISABLED and i can't figure out how to enable it.  Any help would be much apprecaited.
