I have been having problems getting ppp0 and eth0 up as concurrent connections, and there are many people with similar problems. It just doesn't 'work' in Ubuntu, network manager has many bugs and wicd may seem a solution, but it has no dialup support.
Why is networking so 'easy' with Windows, and yet so 'hard' in Ubuntu ?
I think this poster said it well.
If new users are to be 'attracted' to Ubuntu, then the networking functions and interfaces, need a serious overhall, and significant re-development.
Let's face it, if a user can't connect to the internet, what good is the OS ? (to them).
People can't even get ICS going. Some can, many can't, what's the problem ?
