Any window hacks for faster speed.

[Tech^salvager]

Are there any window reg hacks for cable internet that lets it be faster in downloads, and are there any hacks for faster upload speeds.
Thanks

If you're talking about "legal" hacks:

thanks
Yes I am talking about legal hacks
I usually maxes out at 200KB when downloading, but one day all of sudden it was gowing as fast as 1.4MBs.

Now does anybosy know if there is anything for the uploads.

Works for dial-up too!

download setup x http://www.xteq.com/
its a really good reg hacking program with alot of plug ins, it has a bunch of stuff to do with internet so give it a try

There is No hack to increase Bandwidth.

The Max that you can do is insure that your TCP/IP is optimized to your type of connections.

The phenomenon of “Surges” in the Download as to do with the way the Bandwidth control kicks in on the ISP System, and the way the browser averages the Download speed.

Download DrTCP: DSLreports DrTCP021 (http://www.dslreports.com/front/DRTCP021.exe)

Run the program, it will show the current settings of TCP/IP parameters. Write them down.

You can change any variable that you want, click Apply, and reboot the computer, if no good; you can always change to your original values.

Start with:

MaxMTU - DSL =1492 Cable = 1500 ISDN = 1322 DialUp = 576

Tcp Receive - 256960 (This is the varaible to play with!)

Window Scaling - Yes

Time Stamping - No

Selective Acks - Yes

Path MTU Discovery - Yes.

Black Hole - NO

Max Duplicate - 2

TTL - 64

Notice it said above Start with

These settings are not written in "stone" there is variability depending on the computer other setting. So try few setting and measure your Download for each setting.

In addition, in case a person has a Router the Router's MTU if set differently can affect the general MTU.

Thanks for the Info Cat5e and The Xenon.

DSL Reports (http://dslreports.com/) in general is a fantastic site. Check the forums fopr specifics to cable - don't be fooled by the site name. TweakTest (http://www.dslreports.com/tweaks), Speed Test (http://www.dslreports.com/stest), etc.. are great tools to optimize your connection.

Wow...thats a crazy increase...
I doubt that came from tweaks...i tweaked mine, i still dl at like 350k , i used to be able to download 400+ k all the time.

[Tech^salvager]

that wasn't from tweaks, it just happened one day when I started to download something. Fogot what it was though

Mine now becomes steady at 600KBps sweet

[ShadeZeRO]

Specs on your comp...
Connection..
Tweaks/mods???

thx :)

i wanna see if i can get mine up there also

Tweak away.

[ShadeZeRO]

Im not getting the RWIN part..

Can you help me calculate it

[Cyan]

The bandwidth field is used to input your total average bandwidth for your connection. Accurate values are represented in Kbytes/sec if my connection could attain 300KB/sec I would use 300 in the field.
To find bandwidth, use a large ftp file, until it even out to your average connection speed. You can use on of these three links if you'd like (just download about half the file or so)

OOL FTP Speed Test
ftp://ftp1.optonline.net/pub/test64

AOL FTP Test

RoadRunner FTP Test
ftp://test.tampabay.rr.com/ftp.50m.sav
Enter the average latency in milli-seconds(ms) for your connection. There are many ways to find the latency of your connection.
Go here

http://www.cable-modems.org/cgi-bin/cm/netdiag/netdiag.pl

And they'll appear at the bottom of the page (all those numbers in the row with "ms" next to them.
below that is the averages etc...
round-trip min/avg/max/stddev = 58.091/58.269/58.743/0.211 ms
MSS is the real amount of data you can send/receive at any given time over your connection medium. MSS is a calculated number from MTU (Max Transfer Unit). Most of the time it is calculated by MTU-40=MSS.
Some common MSS sizes are:

Ethernet: 1460 (1500-40)
Cable: 1460 (1500-40)
aDSL: 1452 (1492-40)
Dialup: 536 (576-40)

go here
http://www.speedguide.net/analyzer.php
and It'll tell you the MSS number that you have, (second listing, below the MTU)

click calculate and there is your idea RWIN value.

[ShadeZeRO]

My MSS is 1460 i guess...
the say my connection is 3.0mb down
and like 256 up?...
my avg ms is like 45...

what else...

are they talking about download speed or what?

[Cyan]

download speed, actual download speed, not advertised speed.

Download half one of the ftp files above and see what the average download rate is.

[ShadeZeRO]

That Analyzer doens't work.

TCP Analyzer FAQ
http://www.speedguide.net/faq_in.php?category=98

more specifically

6. The TCP Analyzer is broken! I'm always getting a white page, how do I fix that?

You have to enable JavaScript in your browser. Depending on your settings, you might also have to turn off your firewall, or expose the particular client. The Analyzer server uses a non-standard TCP port.

11. The TCP Analyzer doesn't work, I can't connect to it ?

You are most probably running a firewall that blocks port 8117. The TCP Analyzer server uses a non-standard port for accepting HTTP conenction and some firewalls might not let you connect to it. You'd have to open port 8117 on your firewall while testing, your PC should be able to connect to this port.

12. How can I connect to the Analyzer from behind a firewall ?

The Analyzer runs a specialized web server on port 8117. If you reconfigure your firewall to allow incoming/outgoing traffic on port 8117 you should be able to connect without problems. Some software firewalls might still not open the ports like they should, and you might still have to disable them in order to get results from the Analyzer.

I use Charter Cable internet I did have it going stable at 6mbps but now are cable has been messing up lately since the lighting storm. Right after the lighting storm passed the cable internet and TV went out. It came back on a couple hours later but I couldn't get it to be stable a coonecting to internet so I decided to take the tweak off both mine and my moms computer. That didn't work that much because it still being unstable downloading some stuff lately

my computer specs are
1Ghz anthlon
512mn of ram
biostar MOBO
1 NIC
34x cd drive
1 30 GB hd with two parttions
1 20 Gb hd
Evga GeForce FX 5600xt
5.1 sound card

[ShadeZeRO]

i allowed that 8117 port, but still doensn't allow me to access it...i also forwarded in my Router also.

[Cyan]

CALL charter,

you can check out different problems users have here

http://www.broadbandreports.com/

But you'r first option should be to call charter and have them do a test or some such thing on your line.

I also assume none of your personal equipment was damaged in the storm.

[Tech^salvager]

nope
The modem is ours too its not rented
So if the Modem is going bad then that maybe it

How bout java?

you can assume that your MTU is 1500 if you've never changed it and use XP/2000, thus the MSS is 1500 - 40. (1460)

if all else fails you can use that number, or look into other ways to find your MTU value (MSS is generally -40 of the MTU value and is the default in XP/2000)

[ShadeZeRO]

i fixed that 8117 problem...i just shut off the firewall...and it works fine now...i turned it back on now ill show u the results...

ShadeZeRO's Test Results from SpeedGuides TCP/IP Analyzer

MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 513920
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled Receive Window = 64240

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
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: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 52 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

[ShadeZeRO]

what is the unscaled? seems kinda low

[Cyan]

The TCP receive window size is the amount of receive data (in bytes) that can be buffered at one time on a connection. The sending host can send only that amount of data before waiting for an acknowledgment and window update from the receiving host. The Windows CE TCP/IP stack was designed to tune itself in most environments, and uses larger default window sizes than earlier versions. Instead of using a hard-coded default receive window size, TCP adjusts to even increments of the maximum segment size (MSS) negotiated during connection setup. Matching the receive window to even increments of the MSS increases the percentage of full-sized TCP segments used during bulk data transmission.


http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcetcpip/html/cmconTCPReceiveWindowSizeCalculationWindowScaling. asp

As it suggests, it is the value you'd have if the Recieve Window Scaling is not activated.

It's not a value that you need be concerned about.

[ShadeZeRO]

ok, than everything else seems ok...

Ill try to mess around with rwin values to find one that fits just right.
