TCP options string = 020405b4

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 49152
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 49152
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)

Your RcvWindow limits you to: 1966.08 kbps (245.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 786.432 kbps (98.304 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = OFF

TTL value is ok.

Timestamps (RFC1323) = OFF

i am using the cablenut 4.02 patch and i set my DefaultRcvWindow to 256960 but the speed guide analyzer says it's at 49152!!!

i even checked my registry in HKEY_LOCAL_MACHINE\
System\CurrentControlSet\Services\VxD\MSTCP
DefaultRcvWindow and it says 256960... WHAT SHOULD I DO?

and my download speeds aren't the greatest...

I asked last time you posted but again, what OS

sorry i will use this post from now on...

im running winME

First you do not have Cablenuts patch installed, lets install his patch first and go from ther, do this:
desktop click on cablenut 4.0
Click on ccs files
then click on cable
Select fast cable 9x
this will enter settings
click on save to registry at bottom, reboot or it will not work
Retest, repost
Also with 4.0 users of ME need to download and install 4xx to 4.02

oh ya... once i get this problem fixed... i was wondering if u were being sarcastic when u wrote this in ur other post--->

"Yes please tell us, I can change my MTU back from 7500, RWIN 999999. don't keep it a secret, hehe"

oh! i found out why the speedguide analyzer read 49152 as my RWIN... it's because i set my ie.5.5 LAN settings to use "automatic configuration script address: http://proxy:8080 so i was wondering if i should turn it off or on in order for my tweaks to work...

Now you go back to other post and enter OS
and I have no idea about the MTU thing or what you are talking about, but the highest you can set it to is 1500, you may set it at anything you like but it will only read it as 1500

Do you have @home software installed on your puter

sorry.. im confusing..

yes i think i have the @home software installed but i uninstalled it... im not sure if the software left any "junk" in my computer though... do u recommend any speed settings to speed up my connection? cuz the speeds im getting arnet too great!

Yes even though you have deleted the @home software do this, reboot, retest, repost:
To get rid of @home proxy server do this
Start, Run, and type: regsvr32 -u ahiehelp.dll
This will disable proxy server.
In control panel, internet options, connecions, LAN settings,
take check mark out of ALL boxes (yes auto detect too)
Reboot

woot! woot! ur the man! my speed improved!

well i used to get 2megs in 8 seconds but 24 is alright... before today my dl was 2megs in 60 seconds!

do u suggest any improvements? im trying differnet RWIN scales but 1027840 and 513920 are giving me the same performance...

What size CPU do you have

what do u mean by size?

i have a p3 733 coppermine
256megs of ram pc133
32meg geforce2 GTS video card...
28 gig hard drive

my computer is in pretty good shape

733 is the CPU size, whos RWIN is that belong to

You need to install Cablenuts fast cable settings and quit playing with that RWIN number, your speed test was not good at all, due to that RWIN

hehe well i got greedy so i set my rwin to it's max (1027840) even though i heard about packet loss and all that other stuff...

alright

i am going to set it back to cablenuts fast 9x setting.

wish me luck!

Just apply Cablenuts fast settings and you will see your speed test is better

umm.. maybe i should test during the early hours... these results vary too much!

Yes this is not time for testing and leave the settings alone till you know what you are doing, downloading fast when you have high pings or packet loss means you have messed up bad, if you want to check pings or packet loss go to www.dsl.reports/tools and take tweak test

icic... where would a good place to learn more about tweaking cuz' i really wanna fix my internet speeds..
