Well I just turned off the timestamps, and since I did, I have trouble getting to some of the pages on this site. It seems too much of a coincidence for that tho'

welz400

mnosteele52,
no, what I am saying is that when I first re installed my win2k system, I used cablenut to enter the values I had previously used.
But then as you may know, I changed the MTU from 1430 (Rwin values = 22290) to 1500 at first, then to 1478. It was at that point I started to tweak my ...

welz400

Hey monosteele52!
how about this then:

WinXP Rwin boxes blanked out in CN, and just tried the analyser page, and wow!

Rwin is 64710....optimised itself eh?

TCP options string = 0204059e0103030001010402
MTU = 1478
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for ...

If you are using win2k, which looks like it, I got a right miserable speed with ...

welz400

Ok thanks for that.

I have found that LM9.0, without a MTU setting, due to a new onboard lan chip/card/whatever, attained a download speed of 53.6Kb/sec, but now with an MTU setting I get 56KB/sec, whereas with my MSwindows box I get 58KB/sec at best.

I will check timestamps setting tho'

welz400

Oh, sorry, forgot to say:
My connection is a 512/256 adsl PPPoA thru a router.

welz400

mnosteele52, I just did a quick install of winXP on my other machine, and leaving the Rwin values blank etc, the speed change on this box is about the same.
With my MTU set at 1478 and a Rwin of 51768 I get 58Kb/sec, and with Rwin values blank, I get 57.8Kb/sec.

One thing I have noticed is that ...

welz400

Hi,
just wondered if there was any posts or forum for tweaking linux.

Oh, I see the analyser page is down just now, it comes back with an eror message on all three of my systems.

Thanks

No I forgot to do it yesterday, so I have done it tonight.

My mal is 1000! That was done as per the guide.; tracert to 5 sites, whilst downloading setupaol6.exe. Then knock out the highest 1188, knock out the lowest 125, then average of other 3: 922 + 1078 + 1000 = 3000/3 = 1000

But, using that to ...

welz400

I just gave it another go earlier this evening, after I read mnosteels' explanation etc., and I thought logically it should work ok, so I went for it again.

No it did not work, I could hardly connect to my ISP; mail program failed! Anyway, I tried surfing and then did a speed test at adslguide.org ...

welz400

Ok, I suppose 57.4 ish is good enough then for a 512 connection...90%, which according to Andrzej's explantaion to me about PPPoA adsl is about the best I can get.

Thanks anyway

welz400

Ok Andrzej, this looks better?
Yes I changed the RWIN value to 17256, and got a download speed of 58KB/Sec and an upload speed of 31KB/sec

Now then, is this the best I can get?

Thanks

OK, OK, I know what CN settings are now.....Duh!

Sorrrry

welz400

Ok Andrzej, no problem, apology accepted over the links. It was no big deal, just a little confusing! :confused:

So, just for clarification please, are you saying that because I have an MTU of 1478 on my PC, it tells the router that the MTU is 1478 NOT 1500????

Now then, question: What are CN ...

welz400

Oh, I forgot to say that the MTU of the router is still 1500.
Would that have any bearing good or bad on my present speeds, bearing in mund my MTU on both machines is 1478.

Thanks

welz400

Hi Andrzej, A HAPPY NEW YEAR to you as well.

Right, I have been doing some tweaking, testing and playing around with settings etc on both machine here, hence my delay in coming back.

Thanks for the 'lessons' on PPPoA, it was interesting reading.
Ok on telling me about my router; not being able to ...

welz400

I can answer 3 of those questions now.

1. I am in the process of finding out this answer

2. There is NO value of 1460 in my registry of both win2k and win98.

3. It is a PPPoA connection, but how do I set it up 'correctly'?

4. I am not using ICS. Both machines are connected to the router.
mmm, so ...

welz400

Ok mnosteele52, but this actually relates to the differences between what I have set my MTU to in both machines and what the analyser test page tells me it is.

I know I have posted other messages here in the past about my MTU setting, but 2 things have happened since then.

First, I have rebuilt my ...

welz400

I have a win2k machine and a win98 machine both linked up to a router on a adsl connection.

When I go to the analyser test page here, it tells me that my MTU is 1460, and not 1500 which I have set it to.
This happens with both machines, and the MTU is 1500 on both machines, or am I looking in the ...

welz400

Tried it for about 10 minutes.....aaaaarggghhh!
Could not surf; it was like travelling by donkey instead of a car

Download speed was 3.5Kb/sec!

Hi,
I have recently had to do a full re install, and everything that goes with it.
Anyway, after using cablenut to re enter the previous settings, and also now I am using a Router instead of the speedtouch adsl modem, I am finding regardless of what seetings I use for RcvWindow, I cannot get past ...

welz400

OK mnosteel, I see what you mean, but do you know where I can get an older version of cablenut? I would like version 4.02.0016. This is the same version I have on my win2k system. Unfortunately I cannot find a copy of that version so I will have to d/load it again. I want this so that I can copy ...

welz400

Sorry mnosteel, I am not sure what you mean there.
That link is about my slow speeds on my Win2k system using a frog modem. I am using the said mentioned SAR 715 router now for both win2k and win98se machines. My win2k machine is fine with d/load speeds still. I am happy, but not so with the win98se ...

welz400

Hi,
I am running a Win98se system through a 4 hub ethernet router, SAR 715 (not a lynksys one).
My download speeds are no better than 31kb/sec, after installing cablenut and using the settings from Dr Tweak's page.

My MTU is set at 1472, using the cmtu tool as well to check, so why this test page ...

welz400

Hi,
as a recent user/requester of help on this site, I have frequently said that my MTU is set at 1430, used to be 1458.
I have also said that it has been advised by users on the pipex support NG.

Anyway, I copied the following from one of the messages on that NG:

welz400

Thanks for the link Andrzej.
I managed to get my RWIN value worked out using the formula given, and now have:

MTU 140
MSS1390
RWIN 22240

Which gives a download speed of between 55kB/sec and 59kB/sec, and an upload speed of 30kB/sec

When I downloaded the file64 given in the link for working out ...

welz400

I almost think I have my speed problems sorted now, thanks to the great guys on this site. You made me help myself.

I did various tracert tests whilst downloading a large file.
I shut off my psp proggies I have been using, until the latency was down to a reasonable value, and it was confirmed that ...

welz400

I have found out what was slowin' me down at times so speeds were inconsistent.
A well known p2p program for getting other ppls files etc. It was the updated version. Will go back to earlier version later.

I have un installed it for now so as to get things sorted with my speed.

I have RWIN at ...

welz400

A couple of questions back for you: Andrzej and mccoffe.

Andrzej:
What do you mean when you say : 'results cannot be bigger that registry setting'
I don't follow you there
Yes I know that TCP Optimiser uses MTU 1500 when testing for MTU setting, but then it tells me to set it at 1430.

Yes I did ...

welz400

Are you a pipex user?

When I run: ping -f -l packetsize http://www.pipex.com or net

the figure I get before seeing the DF set message is 1402, which makes the MTU 1430

welz400

Does that include a router?
I have a win98 machine on a lan which also needs access to the internet from time to time. At the moment it uses my win2k machine as a gateway.

Oh, what about my linux system?
The latency values are much less with linux as I said earlier.
Why isn't linux affected the ...
