Wi-Fi: No Hardware Installed after replacing wi-fi card

My wifi has been dropping intermittently over the past few weeks (on multiple networks too) and would only re-connect after I completely restarted the device. I replaced the board but after installing the new AirPort/Bluetooth Board it still isn't connecting and now I'm getting a "Wi-Fi: No Hardware Installed" message. I even opened up my computer again to ensure that everything was connected properly. When I did this it did connect for about 15 minutes before kicking me off the wi-fi again, thus forcing me to restart the device, to which it then said "No Hardware Installed".
