I already have wifi built into my laptop thanks.
Built in means that it is comes with wifi ability right out of the box. So, you will get built in wifi if you buy a laptop that has wifi built in. In the specifications, look for WiFi, WLAN or for 802.11b 802.11g 802.11n and the laptop has the capability.

The majority of laptop manufactures have incorporated Wifi in their laptops. In fact nowadays it would be difficult to buy a laptop without Wifi. Check the popular laptop manufacture websites such as Dell, HP, Compaq, Acer, Apple, Lenovo..etc to find out which laptop models include Wifi.
If your laptop doesn't have Wifi included you can buy a USB Wifi adapter at any computer store. The adapter is the size of a standard USB memory stick, with the exception that it has a 802.11 chip and antenna in it. The setup is pretty simple. Simply install the driver that's included onto your laptop, plug in your adapter and your should be ready to connect! :-)
