I made the change manually but I noticed a difference.
Windows 98/Me:
1. Run the Registry Editor (REGEDIT.EXE) on one of your "Client"
machines.
2. Navigate to HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\
Services\ Class\ Net\.
3. Under that branch, find a key (numbered, such as 0005) that
contains has TCP/IP assigned to the DriverDesc value.
4. Select New from the Edit menu, then String Value, and type
MaxMTU for the name of the new value.
5. Double-click the new value, choose the Decimal option, and type
the MTU value determined above.
I don't see a "Decimal option" but I typed in 1454 anyway.
6. Click Ok when you're done - you'll need to restart Windows for
this change take effect.
7. Repeat this for each Client machine.
I also saw another String there called IPMTU and it's Value Data was 1400.
Since DriverDesc is my Dialup and I'm using DSL, what is the IPMTU?
