Hi,
If you have no internet because the ethernet controller was not installed, you will need to download the ethernet drivers from another computer.
To do this, you will need either the motherboard model or the ethernet controller model. Search google for your motherboard model, and then on the drivers page, find "LAN drivers". Download the drivers, save them to a usb and transfer and install them to your pc.

I the Ethernet card removed complete from your system or you mean to say your system do not detect your Ethernet card.

If the system do not detect your Ethernet card, then it is more of drivers related issues.

Re-install the drivers of your Ethernet card and try to connect.
This should solve your issue.

If there is no Ethernet card in laptop. Then, get one, install drivers for the same.. and try to connect. It will work.

It's possible the drivers are not installed.. To check if drivers are properly installed for the Ethernet card, if you have win XP
* go to Start>Control Panel>System> click on Hardware tab, then Device Manager
- once you're on Device Manager, look for network adapter, you should see something like "Via Rhine II Fast Ethernet Adapter", this is just an example, you may have a different brand of Ethernet adapter
- if you can see the Ethernet Adapter and it has a green icon beside it, it should be working fine, you can also double click on it, to view the Status
- if you don't see the Ethernet Adapter on the list, look under the section "Other Devices", if you see an "Ethernet Controller" on the list with a yellow exclamation point, it means the drivers for the Ethernet Adapter were not installed, which means the drivers has to be re-installed
- you need the manufacturer cd for the drivers

*Now if there's no "Ethernet Controller" on Other Devices section, it's possible the Ethernet card is not being detected by the computer
- you may have to unplug the Ethernet card physically from the computer (computer must be completely turned off) then try to insert the Ethernet card again and boot up the computer, if the computer detects the Ethernet card, you need to install the drivers
- If the computer doesn't detect the Ethernet card, most probably it's busted. You may have to replace it.. You can also try to install the Ethernet card on a different computer just to check if it's really the Ethernet card or the motherboard that's the problem..

use driver updating software ie driver magician. it scans ur outdated drivers and automatically downloads drivers that r compatible for your computer.............

go to device drivers and update the Ethernet drivers
