But if I recall, Ubuntu still lets you set up internet off of their Live CD prior to install, so I doubt this is the issue.
== Do you mean here that you have run Ubuntu in live cd and it succeeded connecting you to internet? The same should have happened with Suse. Experience have it that almost every live cd of any distro today automatically obtains the needed IP then connects to internet.
--Is your modem intended for a "dial-up" internet connection? If this is the case you must let us know "what" is your modem. If it is a modem/router to a broadband then it is okay.
--So this is what you should do if you really want to find out if you can run suse in live cd:
~~~ see to it your connection is good and the modem is on; then boot from live cd
~~~ on terminal try this:
root@host--# /sbin/inetd start [let us know how it responds]
root@host--# /etc/rc.d/rc.inet1 restart [let us know how it responds]
then launch your browser for a try. If this fails, give us report of these commands:
root@host--# ifconfig -a
Hope this helps.
