Today I test install VL59 on one of my Dell latitude D600 and I also have the problem to connect to network using the wireless. But then I try "dmesg" from console as root and from the output I saw something like
eth1: Radio is disabled by RF switch
then I reliase that I can enable or disable the wireless from hotkey for Dell laptop. After I enable the wireless all work well.
Maybe your laptop have the same function as mine. Have a try.
There is another way of find out whether your laptop have built-in wireless is to disassemble the laptop. Usually the wireless card is mounted at the bottom of the laptop. Try to look for it and give us the brand/model.
