I assume you're on windows.
If I recall anything correctly, you should be able to do just that by connecting the two computers together and sharing the internet connection.

On the laptop:
Search for 'view network connections' in the start menu and click the control panel search result.
Right click on 'wireless network connection' and select properties.
In the sharing tab, check 'allow other network users to connect through this computer's internet connection' and select 'local area network' from the drop down below.

Then click ok and connect your computers up. Should work.

Note, I haven't used Windows in a while and I'm not entirely sure of these steps on newer Windows versions.
Do leave a reply if you require further assistance.

If you have an android there are apps that let you use your phone as a WiFi dongle, almost like a hotspot

Outside the US that app is called system settings and you can share your connection via wi-fi and/or USB and get the same speeds you'd get on your phone for no extra cost and on every contract provided the phone supports it which it should if it has proper networking hardware.

NONONONONO!

Internet Connection Sharing is for when your computer is connected straight to the Internet. If you're connected through a router, it won't work, plus it will fuck up your laptop's wifi too.

What you need to do is select the LAN adapter AND the Wifi adapter, right-click, and press "bridge connections". If you've already tried Internet Connection Sharing, you'll first have to go into each adapter's properties and remove them from Internet Connection Sharing.

Yeah no. Android now has native support for vnets on the cellular interface, and puts tethered packets on a different vnet than packets originating on the phone, thus allowing cellular providers to bill them separately.
