MTU on a Poor Line (1)

1. Select your Dial-Up adapter from the dropdown box.
   
2. If you are not connected to a TCP LAN check the RWIN box (if it isn't already checked).
   
3. Press "Optimum Settings".
   
4. Press "Update Registry".
   
5. Close MTUSpeed and reboot your computer.
   
6. You can try increasing your MTU using the instructions in "good line" but it very possible that line noise may cause excessive resending of packets. As these packets are larger than the optimum settings you may get reduced throughput.
