MTU = 1472
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1432
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 255552
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 63888

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
504064 (MSS x 44 * scale factor of 8)
252032 (MSS x 44 * scale factor of 4)
126016 (MSS x 44 * scale factor of 2)
63008 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 10222.08 kbps (1277.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4088.832 kbps (511.104 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 52 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 01000000

Precedence (priority) = 000 (routine)
Delay = 0 (normal delay)
Throughput = 0 (normal throughput)
Reliability = 0 (normal reliability)
Cost = 1 (low cost)

I have a ADSL 512 /128

I used CableNut Adjuster and TCPOptimizer....

Did you try to get the mtu up at all to 1492 also what wndows verison you got and make and model of the router??

SG TCP Optimiser Already Set at 1492 DSL(PPPoE) Optimal Setting....

I have Windows XP Pro

And my modem is: Webexcel PT-3812

Got it set up as Half - Bridged Mode

This why i'm asking about the mtu up above it saids 1472 in the optimizer try the mtu at 1480 apply changes and reboot if we get the mtu to 1480 or 1492 either or no diffrence..

KeYmAkEr · Post by **KeYmAkEr** » Sat Feb 28, 2004 1:43 pm

tried the 1480 mtu setting but made noe difference....ohh.well

mccoffee · Post by **mccoffee** » Sat Feb 28, 2004 2:21 pm

The mtu makes little difference were not done i have give you more settings

Try the following in cablenut

. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

2. Open IE and select tools - internet options - connections -
LAN settings, make sure NOTHING there is checked.

3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.

7. Make sure you do the faster web page tweak in Read1st link.

8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.

9. Install Outpost Firewall http://www.agnitum.com/products/outpost or Sygate Firewall http://www.sygate.com/, both have FREE and Pro versions and are heads above ZA.

10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 http://www.grisoft.com/us/us_dwnl_free.php is an excellent FREE AV app.

11. Make sure you have ALL of the latest Windows Updates.

tried the suggested cable nut settings.....but still no luck.....it's the same...

What's your speed and where you testing at???

KeYmAkEr · Post by **KeYmAkEr** » Sat Feb 28, 2004 4:47 pm

512 down and 128 up ADSL........using the SG TCP anaylzer (Australia - NSW)

mccoffee · Post by **mccoffee** » Sat Feb 28, 2004 4:53 pm

The analyzer isn't a speed test http://www.testmyspeed.com/speedtests/international.htm

Try some here at the aus sites

I got 42330 cps is this alright?

That sounds good

Follow the fix HERE for your MTU.

KeYmAkEr · Post by **KeYmAkEr** » Tue Mar 02, 2004 2:41 am

I don't use Windows buit in PPPoe , I use that only in the router settings.....does this patch still apply to me?

And I don't dial in to connect to the internet , I put all my login details in the router's PPoe's section.

mccoffee · Post by **mccoffee** » Tue Mar 02, 2004 9:02 am

It would've been nice if you had told me that what is your make and model of router.

KeYmAkEr · Post by **KeYmAkEr** » Tue Mar 02, 2004 9:17 am

Webexcel PT-3812 4 switch Router.

mccoffee · Post by **mccoffee** » Tue Mar 02, 2004 9:29 am

After 20years of finding the manu i found the fix 10.0.0.2
logon on to router look for configuration click on wan change the encapsulation type to ppoe.

mccoffee · Post by **mccoffee** » Tue Mar 02, 2004 9:32 am

also in wan make sure mtu is 1492 mru is 1492 and mss is 1452

KeYmAkEr · Post by **KeYmAkEr** » Tue Mar 02, 2004 12:41 pm

There's :
-PPPoE VC-Muc
-PPPoE LLC
-PPPoE None

I've got it set at PPoE LLC

Changed the mss from 1432 to 1452

--------

No luck...it still the same....

mccoffee · Post by **mccoffee** » Tue Mar 02, 2004 1:18 pm

PPPoE None is what you want

KeYmAkEr · Post by **KeYmAkEr** » Tue Mar 02, 2004 2:22 pm

What's the difference?

If I choose the PPPoE None....will I have to have the Windows PPPoE login thingy?

mccoffee · Post by **mccoffee** » Tue Mar 02, 2004 7:48 pm

No you shouldn't need xp thingy

http://www.goldweb.com.au/support/confi ... bexcel.php this is the manual

mccoffee · Post by **mccoffee** » Tue Mar 02, 2004 7:53 pm

http://www.carricksolutions.com/am.php#26 try this step to for the 1492 or 1480 try both too see if it sticks. This is real easy step

KeYmAkEr · Post by **KeYmAkEr** » Wed Mar 03, 2004 1:52 am

uhh...which number do i do? there's so many

mccoffee · Post by **mccoffee** » Wed Mar 03, 2004 1:52 am

Use 1492

KeYmAkEr · Post by **KeYmAkEr** » Wed Mar 03, 2004 10:18 am

no...i meant which number step not mtu

That's only for Windows ME not Windows Xp Pro

mccoffee · Post by **mccoffee** » Wed Mar 03, 2004 3:23 pm

That for all if you are using me that step is different
