Help lost wifi connectiion

[mauron]

I spilt a few drops of red wine (shiraz Austrlian very nice) down the back of my Dell laptop and now it cannot find a wifi router.

Have I killer the onboard card, as the wifi icon isn't lit?

Everything else seems to be working ok, I can connect using a ethernet cable.

HELP!

Every Dell I've owned has a hardware Wifi switch. Are you sure that's not been knocked as you were mopping up??
