How do I change the MTU or RWIN using the DrTCP tool?
Important Note: Windows Vista has an auto-tuning function that automatically adjusts your settings, so tweaking is not possible. You can disable auto-tuning for troubleshooting connectivity issues. Click here to find out how. Step 1 Download DrTCP here and open the application. Step 2 Enter the desired MTU in the appropriate field. Very Important Note: Due to additional overhead you must use an MTU of 1492 or less when utilizing PPPoE connectivity (which is the default standard for BellSouth connectivity). Some applications may require an even lower MTU to work properly. Additional information about finding your optimum MTU can be found here.
