The problem is that my Ubuntu server 12.04 can only be accessed by ssh. It connects to the router with a wifi wpa 2 encryption. Im not using a firewall, and it should be sharing to both windows and mac using samba and afp. This works when the connection is wired, but not through the wireless? Can anyone directe me or give me any ideas as what to try. Thank you in advance.

Here is a little more detail

iwconfig (I think the problem is here - I do not have an IP address?)

lo        no wireless extensions.

There is nothing problem in your system configuration. reconfigure your router . Please check dhcp and make sure that your internet connection is shared.
