I've tried connecting my xbox 360 to my westell 7500 wireless router directly with a wire and through wi-fi. What are some suggested fixes? The network connects but the internet does not connect. My laptop and cell phone are able to connect through wi-fi but my xbox is getting the mtu error. I also tried adding the xbox to port forwarding in the firewall settings for both host and dynamic. Any suggestions would be appreciated.
The router should be automatically setting its MTU to the fastest setting for your connection. If not, you can manually set it. Login to the router and change the MTU connection settings in there. This will force all your connections to use the MTU your select. The Xbox site suggests any MTU settings over 1374. 1500 is the maximum this can be set to. If you are still having troubles, you will need to reach out to Xbox support for further assistance.
