How do you connect to the net? Through a router, or are you part of a network? Or is it directly through your modem?
Here is an excerpt from the Readme that is on your Freelancer disk!
XII. Multiplayer Troubleshooting
1 Home networks and dial-up connections - If you have a network card and you dial in to the Internet via modem, you may have trouble launching multiplayer games. If this occurs, disable the device that is not providing your Internet connection and try again.
2 Disconnection from ISP - If you are disconnected from your ISP during game play, you will be dropped from the game. Upon your return, you will be reinstated at your last location.
3 Two TCP/IP devices - If you are experiencing issues with dropping network connections or a lack of ability to connect to Freelancer servers, please attempt the following:
o Exit Freelancer and ensure that you have a functional network / Internet connection.
o Disable the device that is not providing your Internet connection and try again.
For information on setting up Internet Connection Sharing or disabling your second TCP/IP device, please see <http://support.microsoft.com/> and search the knowledge base for instructions specific to your operating system. If you are uncertain about making any changes, check with your network administrator, if applicable.
• Routers - Ensure that you have the latest firmware updates from the manufacturer. You do not need to use a computer on a DMZ in order to run a Freelancer server. If you are uncertain about making any changes, check with your network administrator, if applicable.
