How to defeat Cisco epc3825 admin?

Question

Cisco

I inherited a router in Bangkok from TrueMovie called Cisco epc3825 and suddenly I needed to use it as a wifi repeater by connecting to another router via WPS. I go to the right address in the admin panel, enter my login and password, it lets me in, but for some reason there are no tabs with all the settings and I can’t do anything accordingly. Where to dig, do not tell me? Google has already searched all over and there are no results at all. I'm attaching a screenshot of the admin.

Answer 1

Perhaps he lets you in under an account with reduced rights, and not under the "root".

Answer 2

This is how the admin panel of a normal person looks like if anything. All tabs are in place, all parameters can be edited.

Answer 3

I also had only 2 ideas:
1) Log in as a stripped-down user
2) Use an incompatible browser (try to log in under different ones)
