Does the 8230 have built in wireless? Only you can tell us. If so, the button turns the wireless radio off and on. Did you try it? If it has built in wireless the software should already be installed. Again, have you tried it? If it has the hardware and software it'll work. If not, it won't.
I just bought NC 8230 but I can't access to wireless internet connection whereas I can do that with HP NX 9420. I saw a button of wireless on the keyboard, does it mean this laptop can surf the net with wireless connection? Any software that I need to install so as to use the wireless?
