How do I
configure my DGL-4100 or DGL-4300 router for Xbox Live?
GameFuel
does not need to be enabled to use Xbox Live. If you have GameFuel enabled,
then Dynamic Fragmentation must be disabled since Xbox Live does not support IP
fragmentation.
Step 1 Open a web browser and type the IP address of the gaming router
in the address bar (default is 192.168.0.1). Press Enter.
Step 2 The default password is blank (nothing). Click Log In.

Step 3 Click Advanced at the top and then click GameFuel
on the left side.

Step 4 Check Enable GameFuel and make sure that Dynamic
Fragmentation is unchecked. Xbox live will not work if this box is checked.
Step 5 Click Save Settings at the top to save the new settings.
