can i gain more speed

i'm using the newly dsl installed in my house and here is the speed test result

MTU = 1490
Unrecognized MTU, or MTU = 0.

RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.

What kind of DSL, MTU is wrong, RWIN is wrong to fix that put a 1 in Tcp1323Opts in adjuster, save to registry at bottom, REBOOT

i dont know what kind. i'm new to this tweaking stuff. please explain. my isp is msn.com

We need to know if you are using PPOE DSL........Do you have to "Dial-Up" your provider with some software or are you connected as soon as you start Windows?

PPOE- has to "Dial-Up"

djicemanfrankie · Post by **djicemanfrankie** » Fri Aug 02, 2002 11:51 pm

its a pppoe i also have a tcp optimizer and i did change the mtu to 1500 but it won,t change after i click apply and reboot

joecool169 · Post by **joecool169** » Sat Aug 03, 2002 12:20 am

MTU for PPOE should be 1492

Open the optimizer click DSL PPOE at the top apply the settings and reboot, then take the analyser and paste in the results Plz

i won't change to 1492 at all. is there anyway in the registry to change it manually so the analyzer will recognize it

joecool169 · Post by **joecool169** » Sat Aug 03, 2002 12:37 am

mnosteele52 suggests some MTU fixes in his help thread here

I would look at that, you need to get your MTU fixed

djicemanfrankie · Post by **djicemanfrankie** » Sat Aug 03, 2002 1:21 am

still no change. the link mnosteele gave can't locate class in the registry. i nedd to fix my mtu if that is the problem.. really appriciate your help guys

Lobo · Post by **Lobo** » Sat Aug 03, 2002 7:49 am

Enter in boxes in Cablenut

Tcp Window Size- 1 at a time 31944 or 63888
GlobalMaXPcpWindowSize- 1 at a time 31944 or 63888
the above 2 places should have same number in

TcpRecvSegmentSize=1452
TcpSendSegmentSize=1452

Try that, save to registry at bottom and reboot

joecool169 · Post by **joecool169** » Sat Aug 03, 2002 11:44 am

Lobo, I just want to know will that make his MTU correct and how?

Just so I know, thanx

djicemanfrankie your MTU is still not right, what NIC are you using?

ScottE · Post by **ScottE** » Sat Aug 03, 2002 1:01 pm

If you are on MSN are you using an Arescom modem?

djicemanfrankie · Post by **djicemanfrankie** » Sat Aug 03, 2002 1:42 pm

i'm on msn and my modem is arescom. nic card is 10/100 on ibm netvista( loww profile card) tried to change it still no change on mtu. tried it with optimizer and reboot completely no change. is there anotherway to change this mtu manually so that analyzer reads it correctly. thanks appreciate the help guys.....

mnosteele52 · Post by **mnosteele52** » Sat Aug 03, 2002 1:52 pm

I'm assuming agentbeast was inquiring if there was a firmware update for your modem (but I'm not sure), you might look here and see if there is. I asked about your NIC because Linksys NICs have a feature called "priority packet" that will lower you MTU when enabled. Also by chance do you using a router? If so maybe you need to update it's firmware.

djicemanfrankie · Post by **djicemanfrankie** » Sat Aug 03, 2002 1:57 pm

i'm not using a router and it's a direct hooked up to the phoneline with dsl filter. tried to use with or with out filters still the same.
model of dsl modem is arescom netdsl 800. check with firmwareupdate no update is available

You're wasting your time trying to change your MTU. It is never going to register with sg analyzer or any other test site. That modem you have actually acts as a NAT router/firewall. MSN sets everything inside of that modem. If you typed in ipconfig at a dos prompt I'm sure you'd have an IP address of 192.168.1.1. Which as we know is a private IP address not a public(internet) one. You're best bet is to change your NIC's MTU to 1490 same as what registers with speedguide's analyser change your RWin to a multiple of 1450 and be done with it. IMHO that modem is a piece of s*** and many others will agree with me. Most of your games won't work through it. One of my friends has MSN and has that modem I spent about an hour trying to change the MTU before I figured out what was going on.

Here is the website for that POS http://www.arescom.com/Arescom/Arescom_ ... DSunit.cfm

If you have 2 speed programs installed, in Cablenut, at bottom click on clear all boxes and Reboot, see if that works

Waste of time. It cannot be changed. Unless you want to try and hack that modem. Which would be against SG rules to discuss.

Lobo · Post by **Lobo** » Sat Aug 03, 2002 4:21 pm

Why can't it be changed?

ScottE · Post by **ScottE** » Sat Aug 03, 2002 4:24 pm

It's an internal setting of the modem configured remotely by msn, you can change the MTU of his NIC, but analyzer is always going to register 1490 since that is what the modem is using to talk to the gateway.

This is directly from Arescom's site

(Question) I would like to receive the NetDSL manager software to configure my NetDSL unit. Anywhere I can download the software ?

Answer: The MSN NetDSL units are are pre-configured per stringent specifications from MSN. Because the units are pre-configured for MSN, we do not offer a software manager to the open public.

Thanks for the info angentbeast

that's one to remember.

Lobo · Post by **Lobo** » Sat Aug 03, 2002 4:27 pm

Try what I said above, you can have 2 patches, but tweak with only one, your MTU should not be 1500, but 1492

NP. I've been through all this before with my buddie. You can read about all the headaches with this modem on dlsreports. Arescom's site also states that these modems are preconfigured to MSN's specs. I say change your MTU to 1490 since that's what the modem is using. Change your RWIN to a multiple of 1450 that gives you the best speeds and be done with it.

Here this is interesting too http://www.arescom.com/New/Trouble%20Sh ... faq.htm#q1

Most of the good stuff is down at the bottom
