hiii
can somebody help me
do i need to set something for the internet to work?

because i have been connecting the internet cable to a desktop i took to my dad's house but it doesnt recognizes the internet or something

here in my dad's house the internet works different i think... a guy that lives a block from this house gives internet to my dad by a box on an antenna, the internet cable comes from there, i guess its wireless? idk... how can i make it work
