Do you know the ip address to get to the login screen? Probably something like 192.168.1.1.
Assuming you are running Mac you can find it with this article: https://www.igeeksblog.com/how-to-find-router-ip-address-on-mac/
After typing that in your browser you should be able to set up a user name and password if you haven’t already.
thanks
I think it's 10.0.1.1 but I will double check
