A6100 Adapter not connecting to 5GHz network

I recently got a problem with the network with my computer. I had to use Ethernet, but it stopped working. I went out and bought a A6100 Adapter, and was so excited because I had never been able to use the 5GHz WiFi that I have at home. It is over 10x faster than what I had. I download the drivers, plug it in, and try to connect to my 5GHz WiFi. What do I see? "No Internet, Secured". 

I have tried basically everything. Reinstalling, resetting my IP in CMD, turned off IPv6, blah blah blah. I NEED HELP!

What has gone wrong?
