I installed this router last year and set up with the tether app. Anytime I updated it or reset it I would simply select the device in the app. It would auto login and that would be it.

I was messing around on it today and noticed it had a firmware upgrade available. So I upgrade it, everything still works etc.

Now when I select that router in list of my devices. Instead of logging me right in it asks me for a password? It already has what I assume is my main password for the account on it yet it doesn't work. Uhm....I know for a fact I wouldn't have made 2 different passwords for the same thing. Tried every PW I use tried "admin"

Is this a bug? 

It still seems like I can log in from the website version but I want to be able to use the app for this. I even reset my password and it still says its wrong for anything other than main login. Even tried the default wifi password. 

Not sure what the model is. . It has the 3 antennas so it could be 3 different ones going by those little pictures. Its called Archer V7 in the app though. Thanks.
