I want to have a ethernet connection on my room but our router is on the other side. How can i have a ethernet connection and how to do it?

This very much depends on your room.
I assume you mean both your PC and the router are in the same room.
Ethernet cables can be as long as 100 metres, so one way would be to have that cable along the wall.
If you use flat cables, like i.e. this:

...you could position it under your carpet. Maybe.
You could use WLAN-devices instead of a cable, but this uses more power, and is less reliable than LAN-cable.
Ask your questions... ;-)
