Internal wireless stopped working

Hi I have a sony vaio notebook i purchased about 6 months ago. It came standard with the intel internal wireless card. A couple days ago out of the blue it started connecting and disconnecting randomly on its own. When it would disconnect it would tell me that nothing is wrong but maybe I should make sure my physical switch is turned on. It has a little switch on the front side to enable and disable the connection. It was on. This started happenening more frequently until it has just completely stopped working at all. I have no light indicator either.

I have reinstalled the card, updated the driver. Numerous times.

I installed a belkin wireless card that worked for the time being so i know its not my actual router.

In fact there are several networks i detect that dissapear when I lose the card signal.

is there a chance its something physical in the notebook? I don't recall dropping it or hitting it.

thanks for the help.

p.s. the reason i dont just use the belkin is I updated to vista today and it doesnt support my belkin card.

 

Perhaps a router firmware update will help.

 

I have also tried that.

When it stops working, it's like my computer is out in the middle of nowhere. It says my card is working but there are no networks detected.

When it works it picks up several networks throughout the complex

 

Perhaps you could take it elsewhere to see if it is having trouble.

 

that's my next plan =D

 

So i turned it into geek squad today to have them send it in. I report an update when I know something.

thank the lord for 3 year accidental damage and warranty

 

mine did that also, just dropping connections all the time. I had to edit the inf and mess with the drivers but that was too time consuming and I wanted a better card. It's rather easy to replace

pop a screw, open compartment
disconnect main and aux antenna, remove minipci
put in a new card, connect antennas, tighten screw,

have a beer.
