Hi JCMTemple,
As we have exhausted all the troubleshooting steps, I would suggest you to re-install the OS and then install the driver in correct order as mentioned Here. A fresh installation of OS will take care of software issues if any and it is recommended to try that before isolating the hardware as the point of failure.
If the issue persists even after operating system re-installation, you may replace the wireless card.
Hope this helps. Please reply with the findings.
