>>It is like regular phone connector, I'm not sure how to properly describe it. But the laptop only has a few USB ports and doesn't have this kind of connector.

>When you wrote "modem", I thought you meant the kind of modem we used in the good old days to connect the computer to a phone line, sorry about that. The connector you are describing is called RJ45. As Naoto writes, it's probably hidden behind a cover, I have also seen "weird" dual connectors.

Another thing to blame Apple for... Macbooks trying to look stylish dropped RJ45, depending on USB / Lightning adapters. Understandable in tablets, but squeezing laptops so much that Rj45 is not available any more is putting form over function...

coming from another dinosaur...
