Preface, I’m not tech savvy at all and am somewhat technologically illiterate. I’ve been living in my apartment for a few years, and had the home internet account transferred to me by the previous tenant. As prices have increased with my provider, I’ve found a few decent alternatives, but all of them use self-installation and I’m honestly a bit baffled on how I’m going to install anything, looking at the current setup

The modem looks like it’s connected via two home phone ports instead of a coaxial port?And the coaxial cable (?) goes out the router and into a hole in the wall? Just wondering what’s going on (am I over complicating this? or just generally wrong?) and whether I’d even be able to install a normal modem by myself, given that the provided instructions from most providers is just “connect the coaxial cable from the router to the wall, plug the modem into a power outlet, voila”, and the setup that came with my apartment looks a lot more complicated than that.

And if it matters, the apartment was built in the early 2000s. Does anyone know what’s going on here, and if I’d be able to install a router/modem myself or would probably need to pay for a technician?
