Help with my RWIN

Recommended Posts

mrproper;I asked VanBuren to explain some of the settings for ADSL & PPPoA to me in your other post I would like to know myself.

dlewis23;If I understand the way that MTU works is that if it is 1 byte too large the packets need to be defragmented & even if it is just 1 byte over it gets its own packet.

This is why with a MTU of 1500 you can Ping testmy.net -f -l 1472 & the packet doesn't fragment but if you Ping testmy.net -f -l 1473 it does fragment.

The ping order varies some with OS's For example yours might work better with Ping -f -l testmy.net 1472 or Ping  -f -l 1472 testmy.net .I just use testmy for an example this is with any site you can ping. The reason for 1472 is the header of 28 bytes. 1472 +28 =1500. & thats -l a small L not a 1 or I.

My ISP blocks ping but I can still show you the basics of what I am talking about.Your ping in the second .jpg will look like it usually does except the latency should be more. Mine is what blocked ping looks like but the packets don't defragment until I use 1473.

The first pic just shows the ping options I have.

The 3rd one shows packets fragmenting.

the MTU is off, since your on PPPoA the MTU should be 1500

read the manual for your router/modem and see if you can set MTU manually to 1500

you show packetloss here

1    <1 ms    <1 ms    <1 ms  192.168.1.1

  2     *       43 ms     *     framed-user-32.62.151.30.ya.com [62.151.30.32]

thats between your modem/router and CO. If you use a phone extension wire, try replace it or bypass it and connect modem/router direct to your house main phone socket.

I had MTU set to 1500 vefore, but I changed because of TCPOptimizer suggestion. I have set it again to 1500. And I repeat the tests now. I don't have extensionss or something like that.

TCP options string = 020405b00103030301010402

MTU = 1496

MTU is fully optimized for broadband.

MSS = 1456

Maximum useful data in each packet = 1456, which equals MSS.

Default TCP Receive Window (RWIN) = 513968

RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)

Unscaled TCP Receive Window = 64246

RWIN is a multiple of MSS

Other RWIN values that might work well with your current MTU/MSS:

512512 (MSS x 44 * scale factor of 8)

256256 (MSS x 44 * scale factor of 4)

128128 (MSS x 44 * scale factor of 2)

64064 (MSS x 44)

Your TCP Window limits you to: 20558.72 kbps (2569.84 KBytes/s) @ 200ms

Your TCP Window limits you to: 8223.488 kbps (1027.936 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 (0)

Make sure to set MTU to 1500 for all adapters, and reboot your PC after that...

Do I have to modify any settings in Cablenut with MTU=1500?

Thank you again.

the cablenut settings i gave you, is made for a 1500 MTU, but your router or NIC adapter is forced to 1496

Vanburen, I forced MTU ** in the router** to 1496 because TCPOptimizer told me that it was the optimum value. Now I have changed again the value ** in the router ** and set to 1500, and rebooted PC. But where else do you want me to change the value?

open TCP Optimizer, and click Custom, change MTU to 1500

scroll in the list of adapters (see the arrow) so all adapters is set to 1500

click apply and reboot your PC

make a new speed test both against Swizz NDT test and testmy.net, also a test here https://www.speedguide.net:8080/

Hey VanBuren;I know your helping mrproper here but how about a lesson on :

Hey VanBuren:Time for a tutorial for me.

The MTU for ADSL with PPPoA is supposed to be 1500 like cable broadband?

The MTU for DSL & possibly ADSL with PPPoE is supposed to be 1492 ?

If I have those correct now please explain why.

mrproper's MTU & MSS have tested off in this & the other post at least with the TCPIP analyzer test.They show MTU1496 & MSS 1456.

I wanted to ask is the TCPIP analyzer test At speedguide.net any good for Windows XP It seems to be more for 9X OS's. The RWIN it reads seems to be MSS based instead of AFD parameter based.

mrproper : Theres no problem with seeking more help & VanBuren knows a lot about these settings.That's why I'm asking him to explain this better to me so I can help someone better the next time.

why the ADSL with

try this aswell

A: Download DRTCP021.zip from Here to your desktop.

For MTU, using the drop-down menu in DRTCP, set your NIC (Ethernet adapter) to 1500. Tab to Apply and click it, Exit, re-boot, re-test, re-post.

If you use PPPoA, follow the same directions, but use your dial-up adapter instead.

dlewis23;Those were questions I was asking VanBuren .He answered that.I don't know why  that is what the common value is yet.Or even that it was until Van answered.I agree with you I always saw the 1492 as the setting for ADSL & other DSL It was supposed to have something to do with the header Like the -28 for checking the ping for a MTU of 1500 .Or the

-40 from the MTU for the MSS value.I read somewhere the exact  reason for the 1492 but I don't remember it right now.I will see if I can find something on it & post it.Just remember I have dial-up & all this is just what I'm still learning.

First of all, I have attache some .jpg files with some screens.

... Well, checked MTU in my [glow=red,2,300]router [/glow] (1500).

... Changed MTU to 1500 in [glow=red,2,300]TCPOptimizer [/glow]: chosen "Intel ® PRO/1000 PM Network Connection" in "Network Adapter Selection". I have two more adapters. I have twice "Network Adapter 1394", but I haven't changed anything of them. What are these adapters? Perhaps a capturer video graph? (I think I have one).

great, now the MTU is where it suppose to be :)

but speed could be better, congestion seems to be a problem, so you could try lower the RWIN a bit.

try this, open cablenut

change TcpWindowSize and GlobalMaxTcpWindowsize to 128480

click save to registry and reboot

now test speed again against Swizz and testmy.net

also test speed against my mirror

I don't think there is something else to do, your MTU is correct, the settings is fine, you could try increasing RWIN, but it might backfire when congestion starts ticking in... As larger RWIN you have, the more speed will suffer when a packet is lost.

With DSL, speed depends on how far away from CO you are, and the quality on the phonelines. That means you ISP cap modem at a certain rate eg 10 Mbps, but distance and quality on phoneline might only hold 8 Mbps max. Thats part of the reason ISP

My ISP advertises download speeds "up to" 20 Mb, and because I am a certain distance from the CO and the quality of my phone line, my router gives me only 9 Mb. But I think that a download speed of 3 Mb is rather bad. I really thnik that this can be improved. I don't know how to because I don't know very much about registry settings, etc.

If you think everything is ok, could you give me al least some advise and values to modify?. I would do tests and compare results on my own.

Thank you, Vanburen.

like he said there isnt much more that can be done, you may just simply not be able to get faster then what you are at now. you could be on the outer edge of DSL's distance. If your anywere over 10,000 feet with ADSL2 your not going to go very fast maby 5mbps max.

dlewis23, if I reached 5 Mbps ** regularly **...... I would be very happy, but you can see the results of my speed tests, all made at different hours and different servers.

I think that "something" could be done, couldn't it?

mrproper;Since VanBuren was helping I turned it over to him.He's very good.I'm not sure what settings you need to make in Cablenut .I looked at the screen shot of yours & it didn't have most of the values filled in.Make sure VanBuren takes a look at this.I think this way it may have even removed some registry setting from your OS.

I'm sure this one should not be blank" DefaultReceiveWindow"

I will see if I can Find a couple of things.for you to look at.

The text files I posted before explain a lot of the Cablenut settings.These are from Microsoft not Cablenut .But they explain what the settings do.To some degree anyway.

This is a link to screen shots of some testmy members Cablenut settings including VanBurens.They might not be for your connection but should show you what the Cablenut settings display should look like Full of settings.If you can't see the settings click on the blue at the bottom of the picture & open it to your image veiwer where you can magnify it.

http://www.testmy.net/forum/index.php?topic=3274.msg30972#msg30972

Also these are screen shots from the cablenut analyzer page.I got the information from your posts & used those.The latency I got from your ping.

These are for the 3 DSL types that were available.They are probably simular but maybe one will work for you.

you could try this page http://www.j79zlr.com/cablenutXP2k.php

and try diffrent settings, just make sure to use 1500 as MTU

latency is usually between 150 and 300 ms, try whats best for you.

good luck

Also these are screen shots from the cablenut analyzer page.I got the information from your posts & used those.The latency I got from your ping.

These are for the 3 DSL types that were available.They are probably simular but maybe one will work for you.

Thanks cholla for your help, but I think that although Vanburen was helping me, you could have continued helping me too. I went to him because he is the author of Cablenut, and I suppose that he is the best to known his own software, but I have never denied your help. (Forgive my english. It's not very good, but I think you know what I mean).  :D

I attach again my current Cablenut screen. And you are right: there are a lot blanks, but it's the .css file that Cablenut gave me, except two parameters that he told me to change. I don't know if it's normal or not but Vanburen gave it to me. I suppose it's ok.

The screenshots you show me (calculated in http://www.j79zlr.com/cablenutXP2k.php) is what you or dlewis23 told me in the original post, isn't it? But my problem was how to calculate the "latency". TCPOptimizer program has a tool to calculate it and doesn't use any file to download. The explained way in j79zlr.com involves to calculate the latency running a tracert while downloading a large file.

So my questions are:

1) Which is the correct way to calculate it? TCPOptimizer or j79zlr.com?

The first one gives me a latency between 490 and 500:

Ping statistics for above hosts:

  Packets: Sent = 21, Received = 21, Lost = 0 (0% loss)

Approximate round trip times (RTT) in milli-seconds:

  Minimum = 89ms, Maximum = [glow=red,2,300] 502ms[/glow], Average =  246ms

The second one gives me a latency of 303 ms (the page says between 150 and 300):

10  236 ms  266 ms  224 ms  The-Planet.ge-4-3-0.ar1.DAL2.gblx.net [64.210.104.58]

11  237 ms  257 ms  240 ms  vl32.dsr02.dllstx3.theplanet.com [70.85.127.62]

12  244 ms  253 ms  253 ms  vl41.dsr01.dllstx4.theplanet.com [70.85.127.83]

13  242 ms  275 ms  255 ms  gi1-0-1.car17.dllstx4.theplanet.com [67.18.116.69]

Traza completa.

As you can see it's not the same (approximately 500 vs 300).

2) When I do a tracert, against which server or page? Is it the same? I live in Spain. Should I choose a spanish server to tracert and/or a file to download from a spanish server? The example above is made against testmy.net and the file is from ftp://ftp.newaol.com/aol6.0/179902/setupaol60.exe.

Thank you very very much!!

mrproper;This was inone of your posts I used the  M ximo = 252ms for the latency in the Cablenut calculator.

If you looked at the pins I did & put in screen shots of when me & dlewis23 were discossing ping in this topic

You will notice I did: ping testmy.net -f -l 1472 If you ping with this it will give you the maximum latency to the site you choose to ping.Just substitute anoter site for testmy if you want to.Do this to 10 different sites & take the average of all of them.

then use that average in the cablenut calculator.

I have made a tracert against google.es ten times and have obtained an average latency of 178 ms (while downloading the large file linked in http://www.j79zlr.com/cablenutXP2k.php).

I have made a tracert against testmy.net ten times and have obtained an average latency of 263 ms. (while downloading the same file).

1) Is it correct doing it while downloading a file or not? I don't understand how affects it to latency (I suppose it gives you a worse value of latency).

2) Latency = (178+263)/2=220,5 ms, is it ok?

Cholla, for these values (Down=9000, latency=220), I attach you the results in CableNut and TCPOptimizer.

Have a look at them and suggest me any change.

I paste you the result of speed tests (made twice each):
