mrproper Posted August 13, 2006 Author CID Share Posted August 13, 2006 Well, cholla, I have decidedto change the rwin value. Tell me if it's correct ot should I choose another one. As you can see in the image I attach, I wonder how is posssible that so different values can work well. 513920 is the highest value and 54240 is the lowest. If as reading in many web pages this value is so important, how can TPP-IP analizer suggest values so different? Vanburen, I am going to read you link about latency and I tell you something in the next post. MrProper Quote Link to comment Share on other sites More sharing options...
mrproper Posted August 13, 2006 Author CID Share Posted August 13, 2006 calculating latency is very hard, it wont be very accurate. So the best way is to test diffrent values.. this is a old guide how to calculate http://www.luwigie.com/tweaks/FAQxp2000.pdf VanBuren I have already read the content of the link and I have a problem. You say I must download two large files (you give some good links) and aftewards I must do a ping (or a tracert to my ISP). If I do a "tracert www.ya.com" (ya.com is my ISP) even without downloading any file, I get all the packets lost in node number 6 (see attached file). It doesn't happen with another pages (dslnuts.com, testmy.net, etc.) What is happening? Is it my fault or is it the fault of my ISP? Perhaps it is something at this time, and it can work in 30 minutes? Against which server can I do the test instead of ya.com? Must I do it with a spanish server or with a foreign one? or must I do it against ya.com? MrProper Quote Link to comment Share on other sites More sharing options...

mrproper Posted August 13, 2006 Author CID Share Posted August 13, 2006 Uys, cholla, I think I wasn't doing well the things. I attach you new files (Cablenut and TCPOptimizer) obtanied through the web page http://www.j79zlr.com/cablenutXP2k.php (download=9000 kbps, upload=512 kbps, latency=220). I haven't made any change in the attached screens. "For optimum performance, consider changing RWIN to a multiple of MSS. Other RWIN values that might work well with your current MTU/MSS: 513920 (MSS x 44 * scale factor of 256960 (MSS x 44 * scale factor of 4) 128480 (MSS x 44 * scale factor of 2) 64240 (MSS x 44)" Where do I change RWIN in Cablenut? I suppose in "DefaultReceiveWindow" field because in dslreports.com suggests me to change RWIN, that is Receive Window (RWIN)=921600 and it's exactly the value of "DefaultReceiveWindow" in Cablenut.

cholla Posted August 13, 2006 CID Share Posted August 13, 2006 mrproper ;;I think we should do it this way if I'm going to help.I went to the speedguide.net site & read some on the TCP Optimizer.I think it iss a good program & I will put some links to the site for you to learn more about it.This way you can use it to determine latency. You misunderstood how I wanted you to get an average latency.I think properly used the TCP Optimizer will help you find the latency. To cover the way I suggested again ping not tracert 10 different sites not Google 10 times then average the latency. First we will try to get you back to the settings you had before you installed the TCP Optimizer .Then we will do the same with cablenut.From there we will use cablenut to display those settings.Once there we will see if we can tweak again.Leave the changes you made to your router . & if you can I think we need to know the distance you are from the CO(Central Office),telephone company terminal,loop what ever you call it.Either the telephone company or your ISP should be able to tell you this. I think you need to call your ISP & ask what speed you should expect not the maximum .This might help determine the correct settings because you have never tested here anyway at 9000kbps.or even close . So do this first: How do I revert my settings to a previous state ? To revert any changes made to your system using the TCP Optimizer, go in its "File" pull-down menu and choose "Restore Windows Default Settings", or even "Restore backed up settings". TCP Optimizer version 2 (and later) makes an automatic backup of the settings it changes the first time you run it. It creates a file of this form "sg_backup_2005-05-11-0903.spg" in the same directory where the program resides. Then you need to restart your computer so the settings will change in the registry. Once this is done we will do the same with cablenut. This is not an uninstall but going back to your previous settings. Quote Link to comment Share on other sites More sharing options...
mrproper Posted August 13, 2006 Author CID Share Posted August 13, 2006 Well, cholla, I have phoned my ISP and they have told me: * Advertised speed: up to 20 Mb * Guaranteed speed: 50% of router speed That is to say, they only guarantee 9000 Mb (my router speed) / 2 = 4,5 Mb. They have just installed me the new ADSL2+ and the router speed will be growing, but this is what we have now. * Distance to central: they didn't know !! I have searched in internet, and I have calculated between 1,5 and 1,8 kilometers. On the other hand, they have given me a new firmware for my router (the latest, june 2006). I have upgraded the router and they have given my all the parameters. Everything is more or less the same, but they haven't changed the router MTU (now it is 1492), but I think we'll have to change it. Anyway, I am going to attach some files with the original configurations and some screens with the router configuration, with which we are going to work. Than you, friend. I hope not to dirturb you very much MrProper Quote Link to comment Share on other sites More sharing options...
cholla Posted August 13, 2006 CID Share Posted August 13, 2006 mrproper;I have been reading some on the ADSL & for it the MTU should be 1500.So You should change that in your router.While there unless you know you need it disable "Universal Plug & Play" If you are between 1 & 2 kilometers then ADSL should work fine. Did you restore your original settings with the TCP Optimizer as I suggested? I also noticed That your CableNut was a lot different.Did you already "delete the CableNut tweaks" in it?

New firmware router doesn' allow a MTU > 1492, that is to say this is the maximum now. I am going to search in www.3com some documentation about it in case we prefer previous version. Previous version was ready for ADSL2+. I don't know about the new one but my ISP assured me that it was supprted too... I need "Universal Plug&Play" because I use Azureus as client bittorrent. I am not able to restore original values for the registry in cablenut and TCPOptimer because I have made a lot of changes. Before consulting you and dlewis23, and afterwards Vanburen, I had already made a lot of changes. Moreover they had installed me the new connection (PPPoA) a few (one or two) days ago. What I mean is that the original configuration was made on my own... We can start working with the current values or with a .css file you think that suits me. But first of all we have to know which firmware is better: the new or the old one. Quote Link to comment Share on other sites More sharing options...
mrproper Posted August 13, 2006 Author CID Share Posted August 13, 2006 Well, I have been investigating. My router is named "3Com OfficeConnect ADSL 11g Firewall Router", but there are basically 3 models: 3CRWDR100A-72 (model sold in Spain) 3CRWDR100U-72 (model sold in Usa/Canada). 3CRWDR100Y-72 (model given by ya.com - my ISP - when you do a contract with them) --> so, I have this one. You can see the different firmwares in "http://www.3com.com/products/en_US/result.jsp?selected=6&sort=effdt&sku=3CRWDR100A-72&order=desc". This model had an old firmware, so I upgraded to version 2.06 (3CRWDR100A-72_10Oct2005.exe), that is to say, I think I upgraded firmware to a new version but as if my model of router was one sold in Spain (I didn't phone to my ISP to upgrade). I think there isn'ty any difference between model A and Y, except for ya.com has bought all the routers in another country (I don't know... but routers are made by many countries and many times it's cheaper to buy in a foreign country). Anyway, I think you can upgrade freely to any model (they will not be very different, I suppose). This afternoon I phoned to my ISP and they gave the new upgrade (there must be a little different than USA version). Well, I don't know much more. That is what I have achieved.

cholla Posted August 14, 2006 CID Share Posted August 14, 2006 mrproper ;I haven't given up on helping you.I don't understand why the two programs won't restore the registry to where it was when you installed then.I thought CableNut was supposed to do this well.That being said we will go with it the way it is now. I really don't know much about ADSL2+ but I did some reading on it.What I found is it doesn't use the additional 8 bytes the regular DSL does.The extra 8 bytes is why regular DSL uses 1492 for its MTU. ADSL2+ doesn't use the extra 8 bytes so its MTU should be 1500.So you need to see if you can get it there. I need to know that to figure several of the Cablenut settings.If you can't get your router to use the 1500 then the calculations need to be made with 1492. We can work with these 2; These two below should be based on AFD parameters DefaultReceiveWindow DefaultSendWindow This is going to take a lot of testing & restarting on your part as we will try to start low & work up until you start seeing a consistent speed drop. The AFD settings are based on multiples of 4096 bytes. So do this: DefaultReceiveWindow =8192 DefaultSendWindow=8192 If you think you want to speed up the process you can test by using larger multiples lik 4 X 4096 or 8 X 4096 & so on. it must always be a multiple of 2. There is one other CableNut setting (which are really registry settings) that may cause problems with ADSL2+. EnablePMTUDiscovery 1 is on & 0 is off Try it off. I can't do much we these until you are sure of the MTU you will be using. These two should below be multiples of MSS GlobalMaxTcpWindowSize TcpWindowSize These are based on MTU minus 40 basically the MSS. The minus 40 comes from subtracting this 20-byte TCP and 20-byte IP headers which are part of the datagram. TcpRecvSegmentSize TcpSendSegmentSize I think the new thinking is DefaultTOSValue set to 0 like you now have it . You might also try increasing this DefaultTTL to 128. After any changes to CableNut you need to restart your computer for the cahnges to go into the registry.

Well, Cholla, I have ugraded my router firmware again (really downgraded). I restored to a previos firmware, but newer than the last one. Anyway, we have available MTU with a maximum of 1500. There is one other CableNut setting (which are really registry settings) that may cause problems with ADSL2+. EnablePMTUDiscovery 1 is on & 0 is off Try it off.

I set DefaultTOSValue to 0 because I read something about it and thought that it was the best. But we can change it to 128 when you tell me. Thank you for the link to my router's user guide, but I downloaded it yesterday. I attach you new screens of cablenut and TCP Analyzer. Before continuing I have one question about router configuration. In "Internet Settings", in "Connect type" I have chosen "Always connected", but I know that there are people who have set it to "Auto - Triggered by traffic". Do you know something about it? Or doesn't it affect very much? Before doing any speed test, why don't you tell me which tests do you want me to do? I will do always the same tests to compare the results. Notice that I am in Spain in case you want to tell me some special test. Mrproper Quote Link to comment Share on other sites More sharing options...

I am going to paste some results of direct downloads with my favourite program: Flashget. I have tested downloading four large files simultaneously. I show you peaks at my maximum speed (my router indicates now 8,6 Mbps). Even one large file (more than 255 Mb) has downloaded at a reasonable speed (495,95 kB/s). The others files you see in the screens downloaded (average) at 144 kB/s, 123 kB/s and 181 kB/s (normal speed?). Well, that's the begining, but what I mean is that I have no problem in direct downloads. I am not very sad with it. Quote Link to comment Share on other sites More sharing options...

Well whatever the average speed of all the users is lumped into the same average. So 384 obviously will never reach the average, whereas the 6.0 should Never be as low as the average.

mrproper Posted August 15, 2006 Author CID Share Posted August 15, 2006 Anyway, I am looking at the results of TCP Optimizer and I can see that TCP Window is limiting speed. "Bandwidth * delay product (Note this is not a speed test): Your TCP Window limits you to: 5139.2 kbps (642.4 KBytes/s) @ 200ms Your TCP Window limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms" Assuming a normal delay of 200 ms, my top speed is 5 Mb, so I think it's normal that I can't get speeds > 4,5 Mb, isn't it?

"Bandwidth * delay product (Note this is not a speed test): Your TCP Window limits you to: 5139.2 kbps (642.4 KBytes/s) @ 200ms Your TCP Window limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms" Assuming a normal delay of 200 ms, my top speed is 5 Mb, so I think it's normal that I can't get speeds > 4,5 Mb, isn't it? Perhaps the solution is modifying the other values you mentioned in you post (mainly RWIN). you should be able to get over 4.5mbps with out a problem, and you are on a 5983kb file but not on a larger one. clear your cache and try this one http://www.testmy.net/tools/test/d_load.php?step1_timed=&step1_size=&step1_validation=&testall=&s=5983&st=st&ni=ni&ta=&top=&tt=1&nobar= then clear your cache and try this one http://www.testmy.net/tools/test/d_load.php?step1_timed=&step1_size=&step1_validation=&testall=&s=12160&st=st&ni=ni&ta=&top=&tt=1&nobar= Quote Link to comment Share on other sites More sharing options...
