How to share wireless internet from laptop to desktop which doesn't have wifi adapter?

I have laptop which is connected to internet using WIFI. I need to connect desktop to internet. Desktop doesn't have wifi card. Can I set up my laptop to act like a switch/router and connect notebook's LAN port to PC LAN port? How to make PC to connect to internet?

UPDATE There is no way to connect to wifi router directly (using cable). Only wifi access is available.

What OS? Windows? Windows 7 use Internet Connection Sharing: http://windows.microsoft.com/en-gb/windows/using-internet-connection-sharing#1TC=windows-7 - You may need a crossover Ethernet cable if your network adapters don't automatically notice a normal patch cable has been used.

You can do it with the tools provided by MS. Nonetheless I'd buy an inexpensive router and use it as wireless bridge instead. – Bruno9779 – 2014-07-03T12:49:00.563

Another idea: There are USB Wi-Fi adapters for ~$10 – endolith – 2017-11-01T14:38:37.443

Copied from Sharing Laptop's Internet to Desktop through Ethernet cord?:

If your laptop has Internet access from wireless, you can use Internet Connection Sharing on the laptop network adapter to share with the desktop.

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

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.
