I'm running Ubuntu 16.04, and I've recently upgraded my wireless card to a Aukey WF-R15 Dual-Band Wireless PCI-E adapter so that I can connect to 5Ghz wifi. Unfortunately I've been unable to connect to the 5 Ghz wifi, but I have been able to connect to the 2.4 Ghz signal. My other devices can connect to the 5 Ghz signal, so it's something with my computer.
Edit:
