When playing a multiplayer game on Xbox Live, network lag can be incredibly frustrating. Lag can cause you to move slower than normal in a game, or cause the opponents to appear to warp around the screen as it isn’t updating their position quickly enough on your system. The following will help you quickly and easily remedy this situation by making port forwarding rules on your router.
First, determine your router’s IP address by pressing the “Windows” button and “R” at the same time to bring up the “Run” dialog box. Type “Cmd” in the text entry field and click “OK.” Now, type “Ipconfig /all” and press enter. Take note of the value listed for “Default Gateway,” as you will need this several times throughout this process.
Now, you will need to establish a static IP address for your Xbox 360. This can be done one your Xbox 360 by navigating to My Xbox->System Settings->Network Settings->Configure Network->IP Settings->Manual. Enter 192.168.0.9 for the IP address, unless you have a known confliction with that in your network (for the purposes of this article, 192.168.0.9 will be used). Now, enter 255.255.255.0 for the Subnet Mask and enter the “Default Gateway” IP from the first step for both Gateway and DNS.
Now we will edit the settings of the router. Open your Internet browser of choice on your computer and type in the “Default Gateway” IP address into the web browser. This will take you to your router’s configuration menus. If you are unaware what your username and password are, which are needed to access the router settings, refer to your router’s user manual. Once logged in, go to the port forwarding menu of your router. If you can’t find the port forwarding section, again, refer to your user manual.
In the port forwarding menu, you will need to create three port forwarding entries. Name them “Xbox Live 1,” “Xbox Live 2” and “Xbox Live 3,” ensuring that each of these new entries is set to “enabled.” For all three port forwarding entries, enter the IP address you assigned to your Xbox, which is 192.168.0.9 in this article, into the IP address field for all three port forwarding entries.
For “Xbox 1,” select “Both” under protocol type and “88” into all port fields. For “Xbox 2,” select “Both” under protocol type and “2074” into all port fields. For “Xbox 3,” select “Both” under protocol type and “3074” into all port fields. For all three, ensure that the rule is always applied if your router gives you that option for the port forwarding entries.
Now, go back to your Xbox 360 and navigate to My Xbox->System Settings->Network Settings and select Test Xbox Live Connection. All tests should now be positive and lag should be a thing of the past. The only reason this shouldn’t work is if your network is just too slow to handle Xbox live, which might be the case for some DSL connections, and will definitely be the case if you are using dial-up.
