The Internet Done Right

A: Some users report that they are unable to complete certain network activities (such as send emails with certain attachments or FTP some files) using an EONI PPPoE connection.

Many users have found that they are able to resolve these problems by running cmtutool.exe on their affected Windows computer.

After running this tool you will be prompted to enter the maximum transfer unit (MTU) your networking interfaces should be using. Try entering 576 to start.

The tool then updates your Windows operating system registry to adjust the MTU on all network interfaces in your computer to the number you specify.

YOU MUST REBOOT YOUR COMPUTER AFTER RUNNING THIS TOOL.

After rebooting, connect to the Internet and see if the network activity that was giving you trouble works.

If you find after a reboot the problems persist try re-running the tool and enter 256, wait for the tool to finish, reboot, and then try again.

If you could be so kind as to reply to this email and let us know if this tool helped you and which MTU value corrected your problem we would really appreciate it.
