I have a notebook and take it with me between office and home. The network connection is static ip address at office and ADSL with a dhcp server at home. I must use system-config-network to change between static ip address and dhcp, in addition to dns server. I tried to use profile in system-config-network, but it only worked with dns server, not ip address. No matter what profile I used, the setting of ip address was the same. I thought NetworkManager can help me before, but it did only with wireless. There was only one wired network setting in NetworkManager. Any suggestions? Thanks. Shi-ming Chen
