I'm not sure if my laptop has WiFi built in. How can I tell?


I don't know if you are running Windoze or Linux, but you should be able to go to the Device Manager (windows) or ifconfig (Linux) and see if there is a network device installed.

You can get WiFi with PCMCIA cards. There are two options: 802.11(b) {more common, slower, widely avail) or 802.11(g) {faster, not as common}. I have a (g) card that will go down to (b) when necessary. You might also be limited on speed in consideration of what transmitter you have in your house. Again, I got a dual speed unit to support more options.

check the model no and serial number on the manufacturers website the mod no will give you list but the system number will give you all the details about your laptop and the parts inside it
