obvious question first, is it turned on?, there is probably a switch on the side.
also, go to network connections, in control panel, see if there is an icon for wireless, is it enabled?
also in control panel, check the system icon, go to hardware tab, then device manager, then network manager, see if the wireless shows up there.
could be hardware failure but if you’re lucky its either turned off, needs to be re-enabled or re-installed.
THANK YOU!!!!!!! I had trouble on a recent trip and when I went to use my wireless, all of a sudden the “wireless radio” wouldn’t turn on. Nothing worked, so I finally went out and got a USB wireless card, which has been failing, not to mention taking up my one USB 2 port. I never knew about the switch. I flipped it and BINGO! I have my wireless back. Thank you, thank you, thank you!!!!!!!!
