I've just finished reinstalling my windows 2000pro and have it totally updated to sp4 and roll up 1(hard drive died again). I have backed up all and I am ready to try tweaking my registry for the first time. I would like to tweak the TCPIP using a set of instructions I first found on this site, posted by widow on Dec. 7th 2000. I think I know what is meant by "NAME"=dword:######### but I am not certain.
Example:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"TcpRecvSegmentSize"=dword:000005b0
This value is not in my registry so I assume I create it. This is where I have a few questions.
1. Do I go to [HKEY.....\Parameters] Then right click it, select new then DWORD value then give it the name "TcpRecvSegmentSize"(without the quote marks I assume)?
2. Do I then right click it and select modify and enter the value(000005b0)?
3. How do I know weather to select hexadecimal or decimal, if not mentioned in the tweak information?
I think I need a type step by step for dummies. Here is the tweak advice from widow, however I have found the same info all over the net.
TWEAK INFO FROM WIDOW.............QUOTE FROM HIS POST
These are the only TCPIP Tweaks you need for Win2k, it is very good at
regulating it own network performance in most areas
Note these TCPIP reg tweaks are only for high speed connections do not use with 56k:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"TcpRecvSegmentSize"=dword:000005b0
"KeepAliveTime"=dword:0015f900
"BcastQueryTimeout"=dword:000002ee
"BcastNameQueryCount"=dword:00000001
"CacheTimeout"=dword:0000ea60
"Size/Small/Medium/Large"=dword:00000003
"LargeBufferSize"=dword:00001000
"SackOpts"=dword:00000001
"TcpWindowSize"=dword:0003ebc0
"Tcp1323Opts"=dword:00000003
"DefaultTTL"=dword:00000040
"EnablePMTUBHDetect"=dword:00000000
"EnablePMTUDiscovery"=dword:00000001
"GlobalMaxTcpWindowSize"=dword:0003ebc0
Also add this one manually to the registry...
Note: Your Individual Interface numbers may differ.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{2
8DCE469-81E3-4E4D-BE67-2453791F1939}]

I have been all over Google this morning(3 hrs at least) and found no step by step answers to my questions, I feel like I must be missing something simple but I would rather ask a stupid question then make a stupid mistake. I would really appreciate any help I can get. Thanks for your time, Hank

OP
Well, I finally decided to use the SG tcp optimizer instead of risking manually editing the registry. I ran a great number of speed test and then used the optimal choice for my speed in the tcp optimizer. It did not cure my problem.
I use a Belkin wireless g adapter to connect to a D-Link DIR655 router which is on a DSL connection.
Before my hard drive failed and I had to reinstall my OS and the rest of my software, I maintained a solid and fast connection (48-36Mbs)with the router and 2-3 Mbs on internet test. Since reinstalling everything, I connect at 48Mbs but steadily drop to 1Mbs and remain there. Not all the time, but a majority of the time. I believe it has something to do with my software since that is all that has changed. My dsl test at 3Mbs on average from the wired computer and there are only two devices on the router, a wired computer and the wireless computer I'm trying to fix.
I believe the wireless connection between the computer and the router is deteriorating for some reason. It is not physical interference as I have had them side by side. I have updated all drivers and firmware.
If anyone has any ideas or suggestions I would appreciate them. I really just want to get my computer back to where it was before. Thank You for your time, hank
