How to connect Dell Vostro 3750 Windows 7 Laptop to Sony 46 inch Bravia KDL-XBR2 using wireless system?

I have wireless network in house, use Netgear router for 3 computers (2 laptops 1 desktop) to access internet (wireless) and main computer (desktop) connects by ethernet cable to router. My Bravia doesn't have ethernet connection and I don't have a gaming system with ethernet connection, is it still possible to connect some type of device to TV to allow my Windows 7 Laptop to use wireless on TV?
