I realize that your post is a bit dated and so would mine but on the off-chance…
First off, can you check to see if you have Airplane Mode selected. If so, uncheck it. Ensure that the Wifi Mode is selected. If all is good, and you have the correct settings, select the Wheel symbol. The one you described as the rotating symbol.
Under Wireless Tab, have you edited the wifi connection points to include your password?
Under Wireless Tab, is there anything that is selected under 'restrict to device"? If so, make sure it is properly selected. BBSID might need to be selected as well. There might be something missing. You can fix that by selecting from the dropdown menu. There should be only one selection.
Open Terminal please and show the output of
ifconfig -a
also
lspci -k
also is your card a USB device? Run this in terminal if it is:
dmesg | grep usbcore
The output should show that it has registered a new device.
Is there anything listed under
dmesg | grep firmware
if there is no output can you
dmesg | grep iwlwifi]
also, what is the output of
ip link
