So, i was stupid enough to think, that a telephone line jack would work as an ethernet cable, because i was in a need for a very long cable for internet. So i put one side into my modem and the other one in my laptop's ethernet port. Of course, it didn't work, so i tried to connect back the REAL ethernet cable, but it didn't go in all way. Like there always is a click sound, when you connect an ethernet jack, but there wasn't a click and, as expected, there was no internet connection. Is there any way to solve this?
