Dont know whether my laptop has a wireless card installed or not, how do i find out?

I own a Acer laptop and bought it 2 yrs ago and it came with it. It should say wireless stamped on the right bottom corner. If you go to Control panel and look under Network Connections it also should tell you if a wireless is installed, if not you can buy a USB wireless stick for $30 CAN at Costco. Good Luck.  more
