OK. Desktop has a USB ADSL Modem and connects OK to the internet. IP address of this interface is a dynamic ISP provided one.
I've also installed a PCI wireless card in the desktop, created an ad hoc peer-to-peer wireless network and given it an IP address of192.168.0.1.
On the laptop, I'ce got built in wireless and can connect to this ad hoc wireless LAN (laptop has been given IP of 192.168.0.2).
So, I can ping the desktop from laptop and vice versa no probs...
What settings do I need to be able to share the internet connection on the desktop? For instance, what does the default gateway, DNs etc need to be set to on the laptop?
Is there anything else I need to do?
