    IP detection problem

    i am using the UBUNTU 8.10 in my college network

    here i have installed two systems with the same...
    the systems are under in our local college network and under a firewall(FORTIGATE)

    we are using the a broadband connection for the internet use......and the college lan is used the same broadband connection.......

    the problem is , when i restart the ubuntu system the network settings will be changed every time
    every time i need to set tthe ip addresses manually for getting the network access

    from this academic year we decided to use the ubuntu in our Network Resource Center (NRC) there are more than 15 computers are there..

    so i need help for solving this problem.......

    Do you have DHCP or static?

    I actually meant inside the network. I for example have configured my server to have 192.168.0.10, and I haven't done that in the router.

    Again, do you have DHCP or static? (inside your network).

    are you booting into gnome desktop environment? If so, I would forgo the network manager and set the ip from command line.
