Short version: The correct way in the latest versions of network manager is to mark which connections that should be evaluated as default connections in the connections editor. Marking as Fix Released.
Long version: To my surprise (and maybe because of bad coverage in documentation, since it seems many people have had this problem and fine-combed google to find a solution), there exists an option that solves this bug in my case, where it only is a problem at home when connecting to my local wireless network in order to share my internet connection, access printer etc (ie not connecting to the internet): In network manager connections editor: Wireless -> Mark my local connection -> Edit -> IPv4 Settings -> Routes -> Use this connection only for resources on its network (If enabled, this connection will never be used as the default network connection) This is a new feature since I started experiencing this issue, so I am marking this bug as Fix Released and instead opening up new bugs for our improvement suggestions. Some new bugs just reported, in order to improve network manager to be more intuitive and flexible on this point: Bug #366774 - Please add new sub-menu "Set default connection" in nm-applet menu with the current active connections, so that default route+DNS can be changed easily Bug #366777 - If the current connection provides internet access, don't change default connection when more device connections become active (Requires that bug #278488 is fixed first though) Then, of course, some documentation / wiki entries about this would not hurt! ** Changed in: network-manager (Ubuntu) Status: Triaged => Fix Released -- If Ubuntu is connected to more than one network (e.g. GSM and wireless) but only GSM has internet access, OS is unable to access internet.
