need new setting

Post by djicemanfrankie »

Mr. steele. is it possible you can give me the setting for cablenut. just got the new laptop here is the spec.
winxp pro
512 ddr ram
my isp is msn and the caps is 768/160
using a linksys wireless router(ethernet connection) and the modem is arescom netdsl 800 unfortunately i can't change the mtu every time i do the analyzer ( mtu is 1490) but when i connect to our network at work it read at 1500. i already downloaded the cablenut but havent install yet. waiting for your suggested setting. here is the result from the analyzer:
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705)
Note: Read the FAQ if the above is not your IP address.

TCP options string = 020405aa01010402

MTU = 1490
Unrecognized MTU, or MTU = 0.

MSS = 1450
Maximum useful data in each packet = 1450, which equals MSS.

Default Receive Window (RWIN) = 20440
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 20440
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
510400 (MSS x 44 * scale factor of 8)
255200 (MSS x 44 * scale factor of 4)
127600 (MSS x 44 * scale factor of 2)
63800 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 817.6 kbps (102.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 327.04 kbps (40.88 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 55 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000


thank you for help. :rolleyes:

also here is the result from dslreports.com

2002-12-13 17:38:44 EST: 650 / 136
Your download speed : 650324 bps, or 650 kbps.
A 79.3 KB/sec transfer rate.
Your upload speed : 136775 bps, or 136 kbps.

HMM that's odd about your MTU, there was someone else in the General Forum that had the same problem with MSN, I'll look into that and see what I can find out about it being set that way. For now we can base your settings on an MTU of 1490, so use the following settings:

DefaultReceiveWindow = 98304
DefaultSendWindow = 20480
DisableAddressSharing = 1
InitialLargeBufferCount = 100
InitialMediumBufferCount = 240
InitialSmallBufferCount = 320
LargeBufferSize = 81920
MaxFastTransmit = 64000
MediumBufferSize = 15040
PriorityBoost = 0
SmallBufferSize = 1280
TransmitWorker = 32
FastSendDatagramThreshold = 1024
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 31900
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 0
TcpLogLevel = 1
TcpMaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfRetried = 80
TcpRecvSegmentSize = 1450
TcpSendSegmentSize = 1450
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 31900
MaxConnectionsPer1_0Server = 10
MaxConnectionsPerServer = 8
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 92

Also 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. Make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot, anything checked in red is spyware and safe to remove.

I wonder if they putting you behind a proxy server, make sure you do my #2 suggestion above to see if there are any proxy settings there.

here is the result (after applying the setting in cablenut) i also did the #2 procedure you requested ( unchecking the proxy server) it seems there is no change to the speed :rolleyes:

2002-12-13 18:08:42 EST: 644 / 136

it did slow down a little bit not much. i did the setting you gave me. here is the result from the analyzer:

my question is am i hitting at least 90% of my caps. if not what else can i change i did the firmware upgrade on my linksys router last night. you have been a great help :rolleyes:

:confused: I did not folow: is MSMfirmware
Developed by Microsoft exclusively for MSN Broadband customers, IntelliSpeed technology
1q can repleased MTU? diferent: WAN (1490) & LAN (1500)???
2q is it router effect? MTU fixed by router?
3q LAN after router is still WAN for MSNfirmware???
4q NIC setings: with router vs corporateNet
5q ICS?
6q proxy
:D PSmay I ask about (any) link to MSMfirmware description ?
OK I found it
What is Microsoft® IntelliSpeed™ technology and what are the benefits?

Mr. steele, so what do you think of the speed i'm getting, is this ok or i need to make some more adjustment. i think i'm just getting 80% of the cap speed. is it possible to get it up to 90%.

Hi djicemanfrankie for now I would suggest leaving the settings as is, I'm still trying to find out why your MTU is limited as it is, when I do find out something I will post it. Your settings are as good as they can be for now, most importantly your RWIN is an even multiple of your MSS, I'll keep you posted. :) :D
