I'm unable to properly share my connection with my laptop. I'm running a Lenovo laptop with Ubuntu 11.10 installed. I'm connected wirelessly. When I connect to a desktop system that I want to "leech" off of my laptop, it continually loops with:

Connection Failed: Activation of network failed.

It appears every 4-5 seconds or so, continuously. I can't seem to get it to work whatsoever. All I did was under IPV4 settings in Network Manager I selected Share With Other Computers.

What can I do to get this gizmo working?
