can't get dhcp to work

[windos_no_thanks]

K-menu>Configurationa>Network?Internet>Network Card Config

Umm, I think that is just a GUI way of starting netcardconfig, which apparently didn't work.

Do you have the kernel module loaded ? (use "lsmod" to list the ones currently loaded)
I think you should have 8139too. If it isn't listed try "modprobe 8139too"
