Network Difficulty

Hello.

I am using a CNet 11Mbps Wireless-B PCI Adapter on a Windows 98 PC and a
CNet Wireless-B USB Dongle on a Windows ME system.

I have succesfully installed the software and have managed to get both
computers conencted over an ad-hoc network.

However, I have no idea how to share files or an internet connection. I have
tried using different protocols and changing various settings etc but none
of them seem to work. They can't see each other in Network Neighborhood and
they cannot share the internet.

I don't have a clue as why they can connect but not actually do anything. If
anyone knows what's going on please help me.

Thanks
