Hi there,
You can enable your wireless lan via quick launch button on the strip , when tapped it will show you blue light when disabled it will show you with orange light, if you see that light is still blue but you are unable to find any wireless network in network and sharing center
simply open network and sharing center > go to change adapter settings right click on wireless network connection and select enable ,
now your wireless should work,
Feel free to contact us if you require more assistance,
Regards, Bilal

press the power button once to wake up the computer. if still doesnt work then you need to do cold restart by pressing the power button for about 5-10 secs to restart
