Wireless connection help (windows XP)

I've got a new notebook. Without internet though. At home I have wireless internet connection so I would like to connect to the internet via wireless network I have on my main PC. How I can do that ?

Do I have to install additional software or drivers on my laptop or what because Control Panel/Network Connections/Create new connection doesn't have any options for creating wireless network...


EDIT:

This is from windows help centre ;


To connect to an available wireless network

1. Open Network Connections.
2. Click the wireless network connection icon, and then, under Network Tasks, click View available wireless networks.
3. Choose the wireless network from the list that appears, and then click Connect


Yeah, I know that I can do that from my PC but my laptop lacks wireless network connection icon. So how do I bypass that problem ? Where is the icon 😲 ??

Does the laptop have a built in wireless network adaptor?

If not, you may have to get one to slot in - or else you can get a USB one.

This is the slot type I am referring to.

Here's an example of a USB one:
