Port Forward Fail WNDR4500, 2 Networks

Hi! I am trying to port forward my server for my friends to play because I have just purchased the game, I have set up my static IP for my router, and the same speeds of 800 mbps Download, at 40 Upload. I port forwarded and everything, but when my buddies try to connect via my IP, with the port of 25565, it won't let them in, and when I try to connect, it keeps telling me that the connection was refused. I checked my router panel, telling me that theres only one device online (my pc), and I reset it so that I can port forward. So when I reset my router, it still had my old Network Name and password popping up on my phone, and I could connect and everything and use it as if nothing was changed, and the new SSID was popping up, and working just fine. So I was wondering, since it says 1 device on the network, does it really mean 1 device, or is it not showing because of the old SSID still working, along side with the 2.4gHz network, and the 5gHz network that was reset to factory. 

Help? I have updated it to the lateset version, and I have the WNDR4500, and is connected to a COX gateway modem.
