How can I share a laptop's Wi-Fi connection through its Ethernet port?

Solution 1:

If you are actually allowed to do this e.g. DHCP is unrestricted and it is simply you want to know how, the easiest way is to go to the network connections page, highlight both the Wireless and Wired internet connections and then right click and choose "Bridge Networks"

If however this is not your network and/or restricted, uses MAC security or anything advanced, you may have problems and need to assign IP's manually and/or install additional software - in this scenario, I usually tie the network card in to an IPCOP or MONOWall Virtual Machine and share it out from there.

You may also have luck using Window's own network wizard, but I cannot really recommend and/or give advise there.
