Upgraded to windows 2000 and need to be tweaked

[deleted_acct]

Ok well ive upgraded to windows 2000 finnally and i need to get back tweaked up. Can you help me out dr.tweak?

[mnosteele52]

You have Cox right? Try my settings:

DefaultReceiveWindow = 384000
DefaultSendWindow = 32768
DisableAddressSharing = 1
InitialLargeBufferCount = 100
InitialMediumBufferCount = 240
InitialSmallBufferCount = 320

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


Also add the following line to your registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters

BufferMultiplier - DWORD - hexidecimal value of 400.

Here i did the analyzer thing

TCP properties for IP = xx.xxx.xx.xxx (ipxx-xxx-xx-xxx.nc.hr.cox.net)
Browser/OS = Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
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) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17520
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:
Your RcvWindow limits you to: 700.8 kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 113 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

[Lobo]

Or the ones in help thread below in sig, whatever works best for you:)

[deleted_acct]

what do you mean by "hexidecimal value of 400"?

[deleted_acct]

ok nvm i see what u mean.

[deleted_acct]

WHAT!!????!!! look what i just got 240 / 294. thats what my speed was on the speed test.

[deleted_acct]

That was a big drop when i had 98 it was at 3010kbps for download on average.

[deleted_acct]

Please someone help im feeling the need for speed dont let a man suffer some heellppp.

[deleted_acct]

Ok well now my speeds are at 1927 / 278
but im still not satisfied. THey used to be in the 3000s but now im getting this crap. UHHH...

[Lobo]

Try settings in help thread below, then try the DOS speedtest or the 64Meg download, not the little 3MB online burst test:)

Chillinhh we went over this before, first try power cycling your modem and set your NIC duplex mode properly. You also might have a line problem since your connection is so inconsistant, you might call Cox and have them check it out.

;) :D

[deleted_acct]

ok how do i set my nic duplex with windows 2000 still getting used to it. Sorry to be so hard to work with.

[Lobo]

For CABLE MODEM only, NOT DSL

RIGHT click the connection icon on desktop (Properties or Connections) and selecting Properties.
If this is an ethernet connection, and if your cable modem's ethernet interface is not specifically listed as capable of full-duplex working (see list), click the button Configure below the adapter name.
Click the tab Advanced to bring it to the front:
In the Property box, the property name to be selected varies according to model of ethernet card. Examples are: Network Link Selection, Media Type, Connection Type, Duplex Mode, or any similarly-named property which can have Values looking like Auto-Negotiation, or 10BT, or 10BaseT.
In the Value box, select a value which either (a) explicitly says half-duplex or semi-duplex, or (b) at least does not say full-duplex [e.g. 10BaseT on its own is OK]. If there is a choice between 10 and 100 with half-duplex, choose the 10. Do not choose 10Base5, 10Base2, or AUI.
Click OK to exit the Adapter settings.
Click OK to exit the Connection properties.
Close the Network and Dial-up Connections window.
:)

OK well i probley need to call cox because my speeds are jumping from way down to way up to ok. Heres my current settings is this good?

[Lobo]

Do you have a speed program installed, whose:)

[deleted_acct]

A speed program? I dont think i do. What do you mean by that?

[Lobo]

Download SG Optimizer to desktop, directions in help thread below in signature. If you have another Speed Program or patch installed you need to uninstall it prior to downloading Optimizer, thanks.

If you want to change other values in registry, see #17 in help thread below in sig:)

[deleted_acct]

Oh well i use cable nut.

[deleted_acct]

So do i need to uninstall cable nut?

[Lobo]

De truth shall set you free, you have old version, get version 4.08:) , try setting's in help thread:)

[deleted_acct]

old version of cable nut you mean?I just downloaded it.

[Lobo]

You need new version 4.08:)

[deleted_acct]

Well it should be that i downloaded it yesterday.

[Lobo]

Check and see if it's 4.02 or 4.08:)

[deleted_acct]

it was 4.02

[deleted_acct]

well i downloaded 4.08 but when i open it up the adjuster and click about it shows its 4.02.

[Lobo]

Try settings in help thread, you should have uninstalled 4.02 before getting 4.08:)

[deleted_acct]

I did

[deleted_acct]

I uninstalled 4.02 but anyways

If system restore is on, turn it off and



In IE, go to Tools, internet options, connection tab at top, LAN settings at bottom, nothing should be checked in this box, NOTHING, No auto detect, no proxy, no automatic configuration script, NOTHING, REBOOT:)

[deleted_acct]

HOw do i know what irq my nic is on.

[Lobo]

Start, programs, accessories, system tools, system information, Click on Hardware R. on left then IRQ's:)

[deleted_acct]

THe internet that once could go can not go anymore. :(

[Lobo]

Call ISP and see if there having problems:)

[deleted_acct]

Well i dont think its the isp because im getting around 800-1036 kbps and last time when i had windows 98 i just tweaked up and got up to 3146kbps which was mostly what i got at real busy times it was 2882 but i think that i just havent found the right tweak yet but i did the best with dr.tweaks settings.

[deleted_acct]

Should i call my isp or just keep trying to find the right tweak?

[Lobo]

Both:)

[deleted_acct]

well im getting around 1757 with dr.tweaks settings but it should be better than that and the online support chat for cox wont work because this error keeps coming up saying that there was an error and that it was gonna restart internet explorer so im gonna go get the phone book and call cox. But i would think that the speeds would be lower than this if it was something wrong with the line or something.

[Lobo]

Chillinhh, Call them
:)

[deleted_acct]

My speeds were perfect until sunday when i upgraded to windows 2000 so theres got to be some setting wrong.

[deleted_acct]

lol im tired of calling them they dont know anything theyll just be like ok when do you want someone out there then theyll come out and just do a packet test to see if i have packet loss.

[Lobo]

Try if you do not have router:

[deleted_acct]

what connection icon?

[Lobo]

Network connections in control panel:)

[deleted_acct]

ohhhhh

[deleted_acct]

I want 10 half duplex right?

[Lobo]

Right:)

[deleted_acct]

That made it worse i did have it on auto mode but when i changed it to 10 half mode it slowed me down to about 830kbps.

[Lobo]

http://homepage.ntlworld.com/robin.d.h.walker/cmtips/index.html

[deleted_acct]

whats that suppose to be for?

[Lobo]

Call ISP and see if it is 10 half or 100:)

[mnosteele52]

Cox supports 10mb half duplex mode, it is possible to have 6-7ms delays and data collisions if the duplex mode is set improperly, did you reboot after you changed the setting? If auto works best for you then stick with it.:) ;)

[deleted_acct]

yup

[deleted_acct]

hopefully ill get the right setting one day.

[deleted_acct]

But i believe ive tweaked the best i can i might call cox.

[deleted_acct]

OK i was on hold for ever just for them to give me a number for technical support. UHH

[deleted_acct]

well there sending someone out thursday.

[Lobo]

Make them fix it, try RWIN 51100:)




Tcp1323Opts set to 0 or unchecked, TcpWindowSize and GlobalMaxWindowSize must be the same :)

[deleted_acct]

How come when i do the tcp analyzer it shows that my rwin is 64240 when i changed it to 51100?

[Lobo]

Try both, Tcp1323Opts to 0:)

[deleted_acct]

I had already had it at 64240 and i think thats what ive done best with.

[mnosteele52]

GlobalMaxTcpWindowSize & TcpWindowSize (TCP/IP parameters) must be the same size..... that is the value the TCP/IP Analyzer test shows, not DefaultReceiveWindow which is an AFD parameter.:)

[Lobo]

Tcp1323Opts set to 0 or unchecked, TcpWindowSize and GlobalMaxWindowSize must be the same

From above



Reboot each time you change number

[deleted_acct]

does the rwin need to be the same as the tcpwindowsize?

[mnosteele52]

TcpWindowSize is RWIN.

[Lobo]

For right now just click on file on adjuster, open ccs files, fast ccs file, don't worry about blank boxes, it uses default value, start new thread please:)
