I am facing a problem here with Ubuntu version 10.4 I am working with. I am having a wifi router and when I start my system, Ubuntu connects to wifi automatically. But if due to some reasons the connection is lost and established again then Ubuntu wireless system doesn't connect automatically and it pops up with a window to enter the key again to connect.
There are many times I keep my system ON with something to download and went away for some time, only to come back and see that the Ubuntu is waiting for my inputs to connect again as router had lost its connection.
Is there any file settings needs to be done so that it connects to wifi without and user input required ? Or is there any shell script or command which can help in doing that.
