TORN

You can yes, it will say set up a new router but you're just setting up adding a router on the app, continue and you'll get through it and will login with the same credentials.

I’ll take a look at my settings and will try a new cables. Perhaps a rat got them. lol. 
as far as my PlayStation it’s hardwired and works great. Wonderful gaming router I just got to fix the other before my wife throws a fit.
