Help, my RWIN values is always 1460.

[sams_only]

I have installed, uninstalled, reinstalled all the correct patches, updated the vtcp.386 and did all kinds of desperate things but my result test is too low. All the setting in the registry are already correct.

I'm not sure why, but the IP in the test result (202.137.2.170) is close to the DNS server in winipcfg (202.137.3.120). I cannot show my own dynamic IP on the test.

I'm using windows 98. I'm located in Jakarta, Indonesia and there's no program installations for my cable provider. My actual kbps is higher from the test result below.

Did I do something wrong?

Thank's

Sam

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) = 1460
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 365
RWIN is 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)

bandwidth * delay product:
Your RcvWindow limits you to: 58.4 kbps (7.3 KBytes/s) @ 200ms
Your RcvWindow limits you to: 23.36 kbps (2.92 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
(comment :it's already 256960 in the registry)

MTU Discovery (RFC1191) = ON

TTL value is ok.

Posted by Cablenut:
Proxy servers are generally SLOWER for your web browsing. This is because it caches everthing to a remote server that is overloaded and just adds more hops in your path. They are intended to let the cable company watch where you go!

Go to Control Panel, internet options, connection tab at top, LAN settings at bottom, click. Uncheck Automatic Detection and uncheck use proxy server, your done.
Nothing should be checked, reboot.retest :)

[sams_only]

Those 2 options were always unchecked, I never use them. I still have no idea what's causing this.

Could you explain why can't the IP in test result show my IP and closer to DNS server.

Thank's

[cablenut]

Sams is the IP you recieve from doing a ipconfig /all in the dos command box the same as the speedguide analyzer is reporting?

[sams_only]

No, the IP's are different. The IP in the test result (202.137.2.170) is almost the same with DNS servers shown in winipcfg (202.137.3.120 & 121). My IP starts with 10.

My cable connection is at the office. I will check ipconfig/all and post the result but wouldn't the results be exactly the same with winipconfig?

It seems that I'm connected to a proxy but there's no proxy setting at all.

Other info: using 3COM USB sharkfin, no ISP programs installed, just 3COM drivers. My comp is running at 450 mhz / win98. All necessary pactches & updates from speedguide.net are intalled. My current downstream can go to a maximum avg of 300-400 kbps.

What I don't understand are my test result:
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 365
whereas some people gets 0 bits & high unscaled rec. window. How do these numbers determined and can I change these settings manually?

BTW, I live 11 hours ahead of Eastern Time, so my replies can take some time.

Thank's guys.

Do you need a stactic Ip? Most cable providers use dynamic Ips. You might try removeing the stactic Ip. Then disable dns. In the tcp/ip properties. Then click on the wins tab disable wins. At the bottom of the page enable DHCP over Wins Resolution. Under IP address tab Use detect ip automaticaly. Under the advanced tab set it as the default Protocol. See if this helps you out with your problem. GoodLuck! :)After you do this . Resetup your configure rations for wrin and so forth!

Good grief, I meant dynamic IP on the first post. I cannot edit my original message, so could anyone with authority please correct it?

The comp. w/cable is not here, so I cannot check for sure. But I'm 90% positive that those are the current settings. I didn't changed anything and those settings above should be win98 defaults, right? And the only protocol installed is TCP/IP.

But tomorrow I will confirm every setting first & post it here. I don't want to give wrong information again.

:eek:

[Lobo]

Yes I believe you can edit first post, just go to it and click on pencil and paper :) :)

[sams_only]

done it. thank's.

[sams_only]

I check the network settings. Everything is already as suggested. According to the test, my IP is 202.137.2.170. When I ping it's 17ms, should be my ISP. My actual IP is 10.1.x.xx (dynamic).

BTW, the IP shown on the test using my dial up ISP's are accurate.

Could you please suggest anything?

Dazed :eek: & confused :confused:

[sams_only]

Well, can't anyone give me some advise?

I guess I will try some things myself, but could anyone please advise me how did I get these two test result?
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 365

Any factors that determine those 2 results?

Thank's

[rmrucker]

Sams - the 10.x.x.x addresses are reserved for LOCAL Area Networks. That is NOT your real *Internet* IP address.

Cable modems work as bridges to the Default Gateway. All of the users on your Default Gateway are essentially on a LAN and all are assigned 10.x.x.x addresses. However, there is also a WAN (Internet) address that you may be assigned -- and it is likely 202.137.2.170. Go here and see what IP address is reflected back as yours: http://www.dslreports.com/ip

You can also go to http://grc.com and download and run Steve's IP Agent. I think it will also reflect back your true IP address.

Then, your RWIN numbers are VERY, VERY strange. I have never seen anything like it. Do me a favor and run the Tweak Tester at DSLR -- JUST to see what you get: http://www.dslreports.com/tweaks

Let us know what they report for your RWIN. Thanks.

[rmrucker]

Oh, those two results are simply read by the Analyzer computers as you packets arrive at Speed Guide.

To get technical, the Window Scale value comes out of the TCP Option string of the SYN packet. The unscaled Window field comes out of the first packet that arrives without a SYN bit (the so-called ACK packet).

The RWIN is simply a calcuation using those two numbers:

RWIN = Window * 2^scale

So in your case, RWIN is equal to 365 * 2^2 -- or 1460.

I don't know the meaning behind why your unscaled window size is the same as the number of days in a year... ;)

[sams_only]

Hi rmrucker. Thank's for the info.

According to dslreport IP, my IP is 202.137.2.170 (same as reported by speedguide test). So 10.xx.xx.xx is a LAN address, but if the above is my real IP, how can I show it? I tried to play online pool game and I can never get through. Probably because my ISP hides my true IP too well?

And the dslreports Tweak test results are:
Receive Window (RWIN): 256960
Window Scaling: 2
Path MTU Discovery: ON
RFC1323 Window Scaling: ON
RFC1323 Time Stamping: OFF
Selective Acks: ON
MSS requested: 1460
TTL: 63
(less any hops behind firewall)
TTL remaining: 44

-Enable TCP timestamping (FAQ #706) for 'long fat' (high ping) pipes
-Input line speed for RWIN recommendation
-Looking good

So, my RWIN values are corectly reflected this time. But I wonder if my comp. is already properly tweaked.

And yes, I wish my computer could reflect Pluto's year as its unscaled windows. It's 90,465 days x 2 x 2 = 361,860. This is definitely better! :)

[cablenut]

...and the rfcmucker casts his evil spell once again...

[rmrucker]

Hahaha. Love that spelling, cablenut! ;)

Sams, I am at a loss as to why the two RWIN readings are different. I'll drop a note to Philip. In theory, they should be the same. I would have believed they work essentially the same way in determining that value.

I must same, the readings on the TCP/IP Analyzer simply don't make logical sense. There must be a glitch somewhere, somehow. Perhaps Philip will have an answer...

I am not sure how you can make your IP address show up on various connections. It obviously shows up correctly on the SG TCP/IP Analyzer and at DSLR. Why doesn't it do this on other sites? Perhaps your ISP is specifically denying you access to gaming sites? I really have no idea.

[sams_only]

Well, it's good to know that my configuration is ok. It wonder if this is caused by my ISP setting. But I'm changing my cable ISP, so I'll post my test result with a new ISP soon.

Thank's
