Been studying this, and seem to be getting nowhere. I am running Ubuntu 9.10, and just got a Nokia E5 smartphone. I want to share my computer's internet connection (no router) with the smartphone. Can anyone simply describe how to do this, so that when my laptop is on the internet, I can share that internet connection with the phone? I have dmasq installed, and have tried making a new wireless connection (no security, etc.). When I do this, network manager spins around, and my phone sees the new connection. The phone only sees the connection as long as the network manager icon is spinning. The phone allows me to try to hook up to the internet, but does not go on to any internet page, and says 'invalid server'. At some point, network manager stops spinning, 'phone disconnected' comes up on network manager, and the connection is lost. Any ideas? (please give any advice as though you were talking to an idiot....) Thanks!
