network-manager (network connections)

[Linda]

Back to setting up with LTS 10.04.1
I tired to set ip address, DNS etc for eth0 with network manager, but it does not work. It does get rid of DHCP but it does not make any of the new setting changes when I run ifconfig eth0 has no address. I have set ip addresses, gw, DNS etc from the command line so it works.
I know you set up DNS in resolv.conf, but where do you set machine ip address and gw so it will stick for reboot. I don't really want to have to remember to use ifcongig and route everytime there is a kernal update.
           Thanks
