Yeah, loads, but you gave us no details. So we admire the problem, but can offer no solution.
Please post the output as root of:
Code:
# cat /etc/hosts
# cat /etc/resolv.conf
# ifconfig -a
# route
If you don't have root, replace the '#' by sudo.
You could mention what your network interface is, (It's not a secret), and pastebin a verbose attempt to connect (e.g. dhcpcd -v eth0) and add the link.
