Dear Rich

Thanks for the interest.  I know the route/gateway and DNS settings but 
cannot set them as KNetworkManager's Manual configuration is not appearing.

Although I boot directly inot a user I studied the grub boot loader and 
have many options
Ubuntu 8.04. Kernel 2.6.24-16-generic
Ubuntu 8.04. Kernel 2.6.24-16-generic
Ubuntu 8.04. Kernel 2.6.24-16-generic
Ubuntu 8.04. Kernel 2.6.24-16-generic
