8. Repeat steps 3??“7 for each client machine on your network (but not the
host).
In most cases, this should solve the problem. However, on some systems,
you may need to set the MTU in another registry location as well. If you??™ve
found that a lower MTU value is what you need, but the above procedure
didn??™t work, try this as well:
1. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
Ndiswan\Parameters\Protocols\0. If any keys in this Registry path aren??™t
there, just create them by going to Edit ??? New ??? Key.
2. Once you??™re in the key, create a new DWORD value called ProtocolType
and give it a Decimal value of 2048.
3. Then, create a new DWORD value called PPPProtocolType and give it a
Decimal value of 33.
4. Finally, create a new DWORD value called ProtocolMTU and give it a
Decimal value of the MTU you determined above.
5. Close the Registry Editor and restart your system when you??™re done.
Test Your Throughput
Throughput is the practical measurement of bandwidth: the quantity of data
you can transmit over a connection in a given period of time.
The simplest way to measure your throughput is to visit one of the many
bandwidth-measuring web sites, such as Broadbandreports.com (http://
www.dslreports.com/stest/) or Bandwidth Place (http://bandwidthplace.com/
speedtest/).

For the most accurate results, make sure you close all superfluous programs
before running the test.
