it's a Dell Inspiron 5150.
the 1394 Connection: it says connected, but internet doesn't work. i tried to "repair" and got this error:
TCP/IP is not enabled for this connection.
I installed my wifi card, which I know works. it is showing "not connected". i tried to click repair and got this message:
windows could not finish repairing the problem because the following action cannot be completed: connecting to the wireless network.
