Dumb question, but I've got sudden IT brain fade for some reason. I've moved into a new apartment in a far, far away country. The apartment has internet via a basic old wired modem (a ZTE 831) with a single LAN port. I wanted to replace it with a nice new wireless router (D-Link DSL-2640U), BUT... ... the new router cannot be configured because there is no way of finding out who the ISP is, let alone what the username, password or other account settings might be. (The apartment is not registered to any of the main ISPs, so the internet might be spliced in from another account, and the details all since lost. Situation entirely normal for this part of the world....) Hence I was wondering if its possible to simply run the single LAN port from the existing modem into the DSL port of the new D-Link, and whether the D-Link would then simply act as a switch and deliver the signal via its 4 LAN ports and the wifi? I'm asking for the simple reason that if I plug it in to "see what happens" and it somehow fnucks up the existing logon, I'll really be up poo creek without a paddle.
