I think you may have a dns problem as indicated by a previous poster.
I'd go back to basics. From the command line try ping'ing an IP address.
I suggest the Ubuntu web site address of, i.e., type:


and see what you get. You should get a repeating line saying you are
getting 64 bytes from this address. Use Contol-C to stop it.

Then try the same, but using the name:


You should get the same results, but if not, then you almost certainly
have a dns problem (disconnect your dial-up while doing this!). I would
then post the contents of /etc/resolv.conf to this list and we can take
it from there.

You may also want to look at the network admin tool in Gnome and see
what it says about your dns servers.
