Need Help with Settings.
« on: September 27, 2002, 08:19:19 pm »
     I have COX HSI here in Tempe,AZ (85282) and I am getting really high pings with online gaming (120-150...peaking to 450+).  My ping to my default gateway (which is in Okalahoma) avg.'s 80-90 peaking up to 120-130 every few times.  The capping speeds are 3mb/256kb.  I have a P-III 1GHZ 512mb (32mb video)laptop running windows XP Professional.  I don't use USB to connect to my router (2ms ping).  I would rather have slower download speeds and high ping and if I can't resolve this issue with COX HSI I am going to try my luck with DSL.  I was wondering if you could give me the settings that I would need for Cablenut to make my connection as effiecient as possible.  Any help would be greatly appreciated.    My TCP-IP Analyzer info is as follows:

TCP properties for IP = 68.99.192.110 (ip68-99-192-110.ph.ph.cox.net)
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Note: Read the 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) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to 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:
Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 43 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

AGAIN...thank you for any help!

Welcome to the Forms apmartin ;D, try the following settings and see if they help:

DefaultReceiveWindow = 384000  
DefaultSendWindow = 32768
DisableAddressSharing = 1
InitialLargeBufferCount = 100
InitialMediumBufferCount = 240
InitialSmallBufferCount = 320
LargeBufferSize = 81920
MaxFastTransmit = 64000
MediumBufferSize = 15040
PriorityBoost = 0
SmallBufferSize = 1280
TransmitWorker = 32
FastSendDatagramThreshold = 4096
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 64240
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 0
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 = 92

Let us know how they work for you. :) ;)

Also since you are using a router set your NIC duplex mode to 100mb full duplex. ;)

How fast should my ping be to my default gateway (for good gaming that is).  After those settings, my ping is doing better.  It averages around 50-60 now.  It will be around 20-30 for 4-6 pings, then peak up to anywhere from 120-240 for one or two pings.  Then it will drop to 30 or 40 again.  Once or twice it even reached up to 500+.  There is no packet lose though.  What else could I do to help it be more stable.  I am willing to do ANYTHING.  Oh...I also have a SB4200 cable modem and am using D-Link wireless.  But it does the same when connected directly to the modem itself.

Your ping looks fine, but if you want it as low as possible get rid of wireless, it might not make a huge difference (it looks good now) but there are things that can interfere with a wireless connection that could effect your latency. Try those settings for a while and see how they do. ;) ;D

Okay...will do.  I will go try my luck at some game servers without the wireless.  Thank you so much...you all reply very quick.......almost toooo quick  ;) (just kidding).  Again thanks...I will see how it goes. ;D

Okay...my ping seems to be a little more stable.  But I am still only getting game ping (avg on many LOW ping servers) 100-200.  I found one server that I sometime got 90 ping.  I did a survey on a few servers and there were cable users that had 40-60 ping.  Is there ANY way to get some better ping? Does DSL just give you better ping...even though you may not have as high of download speeds?  

What I have now:
