How to set up a router purchased from a provider?

Question

Computer networks

Good time of the day. Spent in my village "internets" yours. =) When connected, they said that the cameras would not cling to my Mikrotik. I had to buy their D-Link 842 router. First of all, I decided how to change the wi-fi password. The family is not stupid, only the lazy one didn’t turn it over and didn’t look.))) The router has already found it only at 192.168.10.1, the default one, of course, is not such an address. And the provider's web interface is there:
And there are no settings. When asked what and how, technical support replied: "It is enough to contact us, the technicians will come and set it up. There is no need to configure the router at the moment, it is perfectly adapted to work in our network." So the question is, if I reset it, will this beautiful picture disappear?)

Answer 1

Most likely it won't go away.
Custom firmwares are designed to be foolproof and are usually configured to work with the ISP by default.
