your wifi usb adapter must be connected before looking

the adapter is connected into the USB port =|
Answer #7
try a diffrent usb port (a back one)
if that wont do it then reinstall the chipset driver
(obtain from motherboard manufacturer site by
the model)
and if that fails too,then reinstall the wifi adapter driver

One of the Ethernet controller is not activated, might be the source of your issue.
However, just reinstall the driver from the official website, it should all be back to normal:
