Why doesn't my default password work?

Spaceeee

I own a Zyxel Model Number: VMG3925-B10A

First things first the default gateway is 192.168.2.1 and I can only access the login interface when I add the port (:8080) at the end. It accepts the username admin, but it wont accept any of the default passwords. 1234 and blank were attempted. 

The internet works with an ethernet/LAN line it just wont activate the wifi. 

I attempted to reset it by holding it for 10 seconds, for 30 seconds, waited for the light to blink, waited for the light to turn red, turned if off and on and i dont really know what else there is to do. If more information is needed I'd be more than happy to answer. I'm really at a loss here.
