In this post, we will discuss troubleshooting for the “Xbox 360 can’t connect to the internet: MTU” error.
As per our research, this error occurs when users try to connect to the Xbox Live. This issue can be present even when the Xbox 360 is connected to the home network without any trouble but still can’t seem to connect.
There can be several reasons for you to receive the MTU error on Xbox 360 when you try to connect it to the Xbox Live server. These issues can be related to the network or the update settings on Xbox 360.
How to solve the error, “Xbox 360 can’t connect to the internet: MTU error?
Fix 1: Plug the Xbox 360 into a wired connection
Are you trying to use Xbox Live through a wireless connection? This might be the issue that is causing the MTU error for your Xbox 360. So we suggest you to try using a wired connection to have a reliable internet connection with stable speed.
Fix 2: Clear the cache on Xbox 360
There is cache data that is stored on the Xbox 360 to make sure that the details that you enter repeatedly can be stored. This helps the data to load faster.
However, many people do not know that the cache data needs to be cleared on a regular basis otherwise it can quickly become an issue for the device.
This is because the cache data uses a part of the working memory of the device and the memory that is needed for other processes is not available.
So try clearing the cache data on Xbox 360 as this might solve the error.
Fix 3: Reset the network settings on the Xbox 360
If the above two solutions did not help with the error, then you may need to reset the network settings on Xbox 360.
Before you take this step, make a note of the settings that are on the network and the password of the network to enter after the default settings are changed.
Simply go to the network settings and click on restore to revert back to default.
Fix 4: Open the ports on the network firewall manually
Some connections on the network are blocked through the network firewall for safety reasons. However, in some cases, the network firewall also blocks the connections that are not harmful.
In these cases, you need to manually open the ports for the specific connection on the network firewall and the platform will be added to the list of exceptions on the firewall. Therefore, the next time you try to connect, the firewall will not block your connection.

Fix 5: Initiate port mapping through NAT
If the error persists then you can also set the NAT to initiate port mapping. For this, you need to use the IP address that is appropriate.
You can try to use: 192.168.1.233
Fix 6: Change the router DMZ settings
You can also change some settings on your router to put the IP address of the Xbox 360 into the DMZ settings.
This is also a setting that is linked to the network firewall settings. When the network firewall settings are blocking Xbox 360 from accessing the internet connection, it needs to be put into the De-Militarized Zone (DMZ) on your router.
This setting will remove the network firewall objections for the IP address of Xbox 360 and you will be able to use the service without any hiccups.
Fix 7: Contact the Xbox Support team
If none of the above-suggested solutions have helped you get connected to the internet on Xbox 360, we suggest that you should consider contacting the Xbox Support team.
