Internet essentials

Hoping to set up Internet essentials for schoolwork, but our rental is a very old house that does not have cable chords... the only chord went to a dish at some point. Is it possible for me to set up internet without cable?
Trying phone chord right now but not working- we have depended on school and library for internet and never set up phone or cable in our house. I am so THANKFUL for Internet Essentials but am beginning to think it’s not going to work for our situation.
