That's exactly it. I've got a 3G modem connected to the box, and I
want other computers to get this connection wirelessly.
I followed this tutorial to get this configuration:

I'm not sure about what mode to use in case I want the computer to be
the router. I found this information randomically defined in different
places while looking for it on the web.
As I said, the client computer sees the wireless network I created,
but can't connect to it. The syslog of the server computer keeps
showing this:
Sep 20 23:46:48 vinicius kernel: [ 3349.172165] wlan0: No active IBSS
STAs - trying to scan for other IBSS networks with same SSID (merge)
Sep 20 23:46:51 vinicius kernel: [ 3351.704879] wlan0: Selected IBSS
BSSID 0e:45:9e:94:06:07 based on configured SSID

Hope it is clear enough now.
Thanks again.
