2 lights white 2 lights Amber xr500

Ok I found my modem online and how to set it to bridge mode, after I did it I rebooted the router. The modem said it was restarting but sat on a spinning logo for a long time and never did anything so I unplugged the modem and after it restarted I could no longer access the modem by entering in the same ip address as before. It just sits trying to load, but never doing anything. I can now access the router by entering routerlogin.net, before I always had to get to the login through a weird ip. So I am guessing it actually did change it to bridge mode because I can't seem to access it. I am also pretty sure the XR online status used to stay on constant and now it is flashing with the other lights. The two ambers are still amber though and the PS4 is no faster.
