Hello guys, and sorry for English. 

Just rented the new apartment, and during the renovation the router was lost, so the landlord ordered a new one for me. The contract is active (i don't know the credentials), but after connecting the DSL cable it says that there's e0 cable error. I assumed that it couldn't be that easy, so should I get the login-password from the landlord and enter them in the router interface, or now it's all automatically sets up and the problem is somewhere else?

Don't have enough German skills to talk with the hotline, so asking here. 

Thanks in advance!
