How to make a Adhoc wlan connection between your Nokia N95 phone and your Windows PC?

Background: I think ad-hoc connections are cool, but a bit tricky to set up. Anyway, save this doc for the rainy day, when you reall really need the connection, but are out of a router.

Windows XP Laptop, preparations
-------------------------------
Define a Wireless network manually (adhoc):

 - Go to Control Panel and open "Network Connections"
 - Right click on "Wireless Network Connection" and select "Properties"
 - Select "Wireless Networks" Tab
 - (You probably need to check the "Use Windows to configure my wireless network settings", but not sure though)
 - Click "Add.."
	- Type the SSID, e.g. "AD"
	- Select "Connect even if this network is not broadcasting"
	- Select "Open" for "Network Authentication"
	- Select "Disabled" for Data encryption
	- Select "This is a computer-to-computer (ad hoc) network; wireless access points are not used"
	- Click "Ok" and "Continue Anyway"
	- Click on the "Advanced" button
		- Ensure that "Access point (infrastructure) network only" is NOT selected
		- Click "Close"
 - Select the "General" tab
 - Select Internet Protocol (TCP/IP), and click "Properties"
 - Note. if you have anything else than: "Obtain an IP address automatically" and "Obtain DNS server address automatically" selected at this point, please MAKE AN NOTE OF YOUR SETTINGS.
 - Select "Use the following IP address", and..
	- Type "192.168.2.1" for "IP address:"
	- Type "255.255.255.0" for "Subnet mask"
	- Type "192.168.2.2" for "Default gateway"
 - Select "Use the following DNS server addresses:"
	- Type "192.168.2.2" for "Preferred DNS server" (not sure if this is needed)
 - Click "Ok"
 - Click "Close"
