Hi legiwei: I have a windows 98 se here of some of the registry tweaks in my system.
I am putting the usual disclaimer don't mess with your registry if you don't know what you are doing.I am not responsible if you crash your system.Backup your registry before doing any tweaks to it.That being said here are the tweaks they are not origionally mine & can be found on the web at various sites but not all at one site.Even if you don't add them it won't hurt to check out your registry to see what is in these locations...Your MTU can be determined by ping if you can ping there is plenty of info on how to do ping on the web.If you can't ping then ask the techs at your isp what it should be.
HKML/system/currentcontrolset/services/MSTCP
"DefaultRcvWindow" without quotes Dword this should already be in the right pane value is your rwin
HKML/system/currentcontrolset/services/MSTCP/parameters
"GlobalMaxTCPWindoSize" without quotes add as string value in right pane it probably won't already be there.The Windo part of this tweak is correct there is not a w at the end of window.The value is your rwin
HKML/system/currentcontrolset/services/MSTCP/Ndi/params
Dword "(Default)"without quotes set at your MTU value
Dword named "@" without quotes set at your MTU value
HKML/system/currentcontrolset/services/class/net/000
"IPMTU" without quotes Dword in right pane set at your MTU value
HKML/system/currentcontrolset/services/class/net/000/Ndi/params/IPMTU
Dword "(Default)"without quotes set at your MTU value
Dword named "@" without quotes set at your MTU value
add values to right pane
HKML/system/currentcontrolset/services/class/net/000/Ndi/params/IPMTU/enum
delete the values for "Large" "medium" & "small" without quotes
Leave tht values for "Automatic" &(default) rename "automatic" your MTU value like "1500" for example
the put in "Automatic" without quotes as the value of the dword
it should look something like this example I could not copy the Dword symbol so where I type Dword is where the symbol would be
Dword 1500 "Automatic"
HKML/system/currentcontrolset/services/class/net/000/Ndi/params/IPMTU/002
Dword "IPMTU" without quotes set at your MTU value
There may be other values here like 003,004,005 depending on your system network put in like the 002 value
HKML/system/currentcontrolset/services/class/net trans/000
Dword "MaxMSS" without quotes set at your MTU value
Dword "MaxMTU"without quotes set at your MTU value
There may be other values here like001,002, 003,004,005 depending on your system network put in like the 000 value
