Cannot connect to internet pls help me

[QUATAR]

HI, im having a problem with my internet connection

let me start by saying what i did.
-the internet was running slow, so i right clicked the icon on task bar, and disabled it thinking i could re-enable it and things would speed up
- when i disabled it. The icon dissapeared. i looked in network connections and my default connection is no longer in the folder. and i cannot re-establish a new connection.

- THINGS IVE TRYED-
-system restore
-looked in device drivers and the ethernet card is working fine (although for some reason it is hidden and i had to click on view / view hidden devices to see it)
-ive tryed to make a new connection

does anyone know any ideas that may help me

Go to your Network properties and you should see the disabled network in there, right click and choose ENABLE
