First check here:

As you can see, your fist thing to test is:
Hot Keys: -Fn+F2 Wireless switch

If that not works, can you provide more information about your system, what Linux distribution are you running?
If you don't know test to run "lsb_release -a" and "uname -a" in the terminal.

Also you can test to run "iwconfig" in the terminal to get some info.

Try what Aron said, but also, if the device merely needs to be started:

ifup wlan0


ifconfig wlan0 up

also, check the BIOS for a wireless device setting that maybe disabled.

On my Dell laptops, I have physical switches. One is an led light that I have to touch, the other is a toggle switch, make sure yours is enabled. As said in the posts above, it could also be a setting in the bios, but, on modern day machines, there should be a physical switch.

If you could give us the output of:

lspci | grep -i net

We can see what adapter your using and give you additional help.

BTW - With the different outputs for wifi adapters, if lspci | grep -i net does't give you any output, try:

lspci | grep -i wire

lspci | grep -i wifi

The more help you give us, the more we can give you.
