Simple Question?
I have my MTU Discovery set to be on, but every time I run a test it shows up as off. Checked the registry and cablenut and it is enabled in both. Anyone have any ideas? Any help would be appreciated. Thanks.

Simple Question?
Sorry about that Steele!
Win XP Pro
768 Meg RAM
120GB HD
Here are my test results:
SpeedGuide.net TCP/IP Analyzer
TCP properties for IP = xx.xx.xxx.xxx ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 32120
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 32120
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 1284.8 kbps (160.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 513.92 kbps (64.24 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = OFF
Time to live left = 52 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

I'm on RoadRunner 3000/384. Any suggestions for my CableNut settings?
Thanks for the reply.

OK great, use the following settings in CableNut:
DefaultReceiveWindow = 384000
DefaultSendWindow = 49152
DisableAddressSharing = 1
InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200
MaxFastTransmit = 64000
MediumBufferSize = 150400
PriorityBoost = 0
SmallBufferSize = 12800
TransmitWorker = 32
FastSendDatagramThreshold = 1024
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 64240
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 1
TcpLogLevel = 1
TcpMaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 64240
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 240
VERY IMPORTANT TO DO THE FOLLOWING
1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.
2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.
3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware. DO NOT CONNECT YOUR MODEM VIA USB!!
4. Clear your temporary internet files.
5. Power cycle your modem, unplug it for atleast 15 seconds.
6. Download, update and scan with SpyBot S&D EXACTLY as I explain HERE & Ad-aware EXACTLY as I explain HERE to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.
7. Make sure you do the faster web page tweak in my Help & Tips link.
8. If you have Zone Alarm as a firewall uninstall it and search your pc for the left over files.
9. Install Sygate Firewall they have a FREE and Pro version.
10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, I recommend using AVG 6.0 it is an excellent FREE AV app. Make sure you set it up EXACTLY as I explain HERE.
11. Make sure you have ALL of the latest Windows Updates.

Simple Question?
I applied your settings for CableNut and seem to have picked up some speed. I was doing pretty good as it was, but now I'm getting 97% of my rated speed. MTU Discovery is still off though. Here are my new Analyzer results and I thank you very much.

Simple Question
I borrowed a router from a friend of mine to see if the MTU Discovery would work with it. Worked every time with no problem at all. When I hooked mine back up, it went back to MTU Discovery=OFF. Does this mean that I need to pull out the warranty papers? Thanks.

If so have you updated the firmware?
