Connecting two laptops wirelessly

I have two laptops (Laptop1 and Laptop2). I want to be able to share files between the laptops wirelessly. I have BT Broadband with a BTHomeHub-9543. I have just the one wireless network connection with the TCP/IP configured to Obtain an IP address automatically. I have followed the knowledge base advice on setting up a wireless connection between the two laptops but keep coming unstuck - suspect because I don't understand the basics well enough. Although I have Windows XP I have not got a Wireless Network tab.
If I change the TCP/IP properties of the wireless connection to: laptop1 laptop2

and subnet

I lose my internet connection.

Can anyone give me a very simple (from basics) complete guide to allowing the two computers to talk to each other.

P.S. the Laptop1 is a centrino duo Intel(R) PRO wireless 3945ABG network connection and a 1394 netadapter (whatever these are)

Laptop2 has a Belkin 802.11g wireless card.

Thanks for trying but two problems, first I don't speak the language and second this is standard wizard and as I explained for some reason my XP does not give me all the options like the wireless network tab or indeed the peer to peer option. This is why I need someone to feed me through the basics on a manual style basis.


1. Check in Device Manager see if the system detected wireless cards correctly and no yellow marks? Right click on My Computer , select properties, then click the hardware tab, check entires there (Network Adapter), there you should see wireless network cards. If not, then you will have to install them. If yes, you are good to go.

2. Click on START > Settings > Control Panel > Network Connections, there you should see wireless connection. If not, you did not install the card correct. If yes, right click on device icon and select properties. There, you follow the link I posted above. You dont need to know the language because you can see the pictures that is step by step to setup. In order to get properties, just right click on device icon and select properties.

Post back when you can.

The network cards are fine and are correctly installed. I understand what you are saying but I can't get the pictures for the networks wizard as per the site configuration - they do not exist on my version of XP - that is the whole problem. It refers to tabs that I can't see. The only tabs I get from the network connection tab in the control panel are General and Alternate Configurations. I repeat the cards are installed correctly.
