Sharing Laptop's Internet to Desktop through Ethernet cord?

[Chiuy]

Hi,

I am trying to connect a Ethernet cord from my laptop to my desktop in order to gain Internet because my desktop lacks a wifi card. I have done this before and was working perfectly fine until I accidentally changed some settings on my networking and now it's not working. So, I'm trying to get some help here.
Right now, both computer knows there's an Ethernet cord connected to each other, but I believe the laptop does not know how to transmit the Internet data to my desktop. Is there a way to share laptop's Internet back to the Desktop?

What I believe I screwed up on my laptop is that I went on "Networking Connection" and clicked on the Internet status, properties, Internet Protocol Version 4 (TCP/IPv4), and I think I accidentally set it to Obtain IP Address automatically instead. There used to be a stuff on the "Use the following IP Address" and now, it's blank. I can't figure it out how to set it back up. Any help is appreciated, thanks.

If your laptop has Internet access from wireless, you can use Internet Connection Sharing on the laptop network adapter to share with the desktop. Just open the network control panel, change adapter settings, right click on the network adapter, select properties, the Sharing tab, and then check the box to allow sharing. HERE is a link to more information.

You can also bridge the two adapters on the laptop to share, although to do that ICS must not be checked.

This also assumes that at least one of the Ethernet adapters is gigabit capable, and thus has auto-MDIX, so you don't need a crossover cable.

Yes we can do this with using Connection Bridge.
