MTU 1484 for DSL XP PPPoE?
MTU 1484 for DSL XP PPPoE?
I am using WIN XP Service pack SP2 with ADSL broadband of 1024/512 kbits/sec through PPPoE.
By editing my registry (NdisWan/parameters/protocols) I have found that my computer can accept a higher MTU of 1484 against the recommended MTU of 1480 for DSL XP PPPoE as mentioned in your TCP/IP Analyzer.
Can you please advise if setting the MTU at 1484 is better than MTU 1480 in my case?
Thanks,
trogers

try thease see if the mtu goes to 1492 either or 1480 or 1492 would work
Try thease in the sg optmizer below me to download and install take another analyzer after applying and reboot

Then select "Apply Changes" and reboot to take effect
VERY IMPORTANT TO DO THE FOLLOWING:
1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need. For a stand alone pc all you need is Internet Protocol TCP/IP.
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 and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware.
4. Clean out your temporary internet files with CrapCleaner.
5. Power cycle your modem i.e. unplug it for at least 15 seconds.
6. Download, update and scan with SpyBot S&D 1.4 EXACTLY as mnosteele has explained HERE & Ad-Aware SE 1.06 EXACTLY as mnosteele has explained HERE to remove any spyware then install and update SpywareBlaster 3.4 to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES. If these 2 programs find a lot of things then please post a HijackThis 1.99.1 log for us to look at.
7. Make sure you do the faster web page tweak in our Help & Tips page.
8. If you have Zone Alarm as a firewall uninstall it and search your pc for the left over files.
9. Install Kerio Personal Firewall 2.1.5, it's FREE and uses next to no resources.
10. Do a FREE online virus scan from Kaspersky Webscan, make sure to check the option to use the EXTENDED DATABASE.
11. Make sure you have ALL of the latest Windows Updates.

Here are the TCP/IP Analzer results
TCP options string = 020405a40103030e01010402
MTU = 1484
MTU is somewhat optimized for broadband. If you're not on a PPPoE DSL connection that limits packet size, consider increasing your MTU to 1500 for optimal throughput.
MSS = 1444
Maximum useful data in each packet = 1444, which equals MSS.
Default Receive Window (RWIN) = 1073725440
RWIN Scaling (RFC1323) = 14 bits (scale factor of 28)
Unscaled Receive Window = 65535
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
508288 (MSS x 44 * scale factor of 8)

I am using a USB ADSL external modem (supplied by my ISP) Billion BiPAC 5102S as shown in this link:
http://www.trueinternet.co.th/cus_hi_driver.htm
There is no router. It is connected directly to the phoneline via a splitter.
I have also disabled all network/LAN protocols on my computer as I am on a single PC.
I have tweaked my settings after following your earlier recommendations, some of the tweaks are as per other websites and on my browsers.
A summary of my actions have been posted on another thread in this forum:
https://www.speedguide.net/forums/viewtopic.php?t=192278
My settings seem to be working very well now.
I was just puzzled why my XP PPPoE allowed me to connect at MTU 1484 instead of the ceiling value of MTU 1480 as stated in many broadband tweak sites.
Thanks

http://192.168.1.254 see if you can login to ur modem hopefully i could find a manual for it the mtu is stuck in there i bet if you have the mnaul or know the login and password
if you see any on thease change them to this
mtu1492
mss 1452
mru1492

I have found the link to Billion's website for my modem
http://www.billion.com/support/download/qig/qig.htm#a01
From what you wrote, I take it to mean that my ADSL connection is not restricted to MTU 1480 as imposed by WIN XP PPPoE but that I can tweak my modem to achieve MTU 1492?
I have read through the manual and datasheet for my modem type at Billion's website and found no reference to manually tweaking MTU values through the control panel.
I will appreciate if you do have further sources that can enable me to achieve MTU 1492.

Hi mccoffee,
Not able to put my modem in routed mode.
While searcing through threads in the forum page, I did notice that the last item in my TCP/IP Analyzer displays a different readout from most others
IP type of service field (RFC1349) = 11110000 (240)
Precedence (priority) = 111 (Network Control)
Delay = 1 (low delay)
Throughput = 0 (normal throughput)
Reliability = 0 (normal reliability)
Cost = 0 (normal cost)
Check bit = 0 (correct, 8th checking bit must be zero)
DiffServ (RFC 2474) = No valid DiffServ equivalent. See the TCP Optimizer documentation, or RFCs 2474, 2475, 2597, 2598, 2873.
The value of most others are a string of zeros.
Those who have similar values as mine for this last item did not need to adjust their MTU values.
Is my modem under "Network Control" and TCP Optimizer is not able to make adjustments to MTU values? Also, when using TCP Optimizer, my modem is not displayed under network adaptors - similar to TCP Optimizer FAQ
15. The Optimizer does not list my network adapter in the pull-down menu ?
If you are using an USB, or some unconventional Network Adapter in your system, it is possible for the Optimizer to be unable to recognize it. When that happens, you can use the "Modify all Network Adapters" checkmark under the "Network Adapter selection" pull-down menu in the Optimizer program. This applies the changes to all network adapters.
You can try our Analyzer online tool to ensure changes have been applied to your particular Network Adapter. Also, feel free to notify us with your exact brand/model adapter the Optimizer has difficulty detecting.
Is it possible for me to tweak the value from 11110000 to 00000000 through the registry?
Thanks.

I dont' think it's possable to change those values however i have to reasearch that some more i don't think you would even need to though, I admit I could be wrong. Those are new features on the analyzer stuff i admit not as familar with yet.
However did the mtu change to 1492 if it did then you should be ready to go.
Also witht the optimizer if you are using a usb modme you don't have to worry about it showing in the optimizer if you are using a network card though private message phillip with the network card you are using also driver version. The driver version can be fiound by right clicking my computer system then device managers, expend network adapters hightlight it then select properties. In the properties under drives is the version of it.

I suspect all the frustrations over MTU values may have come from my ISP provider's web proxy server.
This is what TCP/IP Analyzer displayed at the top:
TCP properties for IP = 203.144.XXX.XXX ()
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5
Notes: Read the Analyzer FAQ if the above is not your IP address.
Your IP (61.91.XXX.XXX) appears to be behind a web proxy server (203.144.XXX.XXX) and results shown might not be for your system.
This is part of the answer to question 14 of TCP Analyzer FAQ:
Last, but not least make sure the Analyzer is examining your IP address and not some transparent proxy server.
I will check with my ISP provider to see if their web proxy server is taking up the missing 8 MTU value. I will let you know of the outcome.
Thanks

I have found that my MTU is set at 1492 even though TCP/IP Analyzer and Tweak Tester II (of dslnuts.cm) showed only 1484.
I use the Microsoft ping command to located the max value of MTU my comp is sending out
http://support.microsoft.com/?kbid=283165
Therefore, if the MTU size is set to 1460 (decimal), the max value of NUM in the following command line can be 1432:
ping IP_address -f -l NUM
and I achieved the max value of 1464 without fragmentation.
So my suspicion is correct. TCP/IP Analyzer can only pick up values of the web proxy and not my comp.
Thank you for your time and hopefully through this period I have also assisted others in this forum.

bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 163.84 kbps (20.48 KBytes/s) @ 200ms
Your TCP Window limits you to: 65.536 kbps (8.192 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = OFF
Time to live left = 54 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
Selective Acknowledgements (RFC2018) = OFF
IP type of service field (RFC1349) = 00000000 (0)
Please advise.. thank you
http://www.dslreports.com/tweaks see if it comes up diifferent on this test if you are on a network the anlyzer may not read it correctly or should say that the analyzer is reading whatever the network is putting out.

try the tweaks test.. always show timed out..
I do a FTP and ping Test on my ISP, according to them I have already getting very good connection, there is noting wrong with my line.

I am try to get more from the tcpotimizer, see whether it can get the most out of the isp. Ultimately i just can't change my RWIN, maybe because of the modem.

Hi guys..........
Trogers............
First i think that you have to unlock your driver MTU, where propably (USB modems) must be in :
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\000n......... n= 0 to 9 (search for yours) and then change it, in the ndiswan>protocol>0>MTUsize.
If you change it with the help of the optimizer, take a look after, in the NDISwan key to see if the dword (MTU) really exists because optimizer deletes the whole dword, if that happens, set it manually by editing in registry. You can see that in the optimizer Registry window, when it ask you to change the settings, before it procceds to restart, just after you press the "apply changes" button.
If u do all that stuff, but analyzers continue gives you 1484, that happens because analyser reads your ISP server and not your com as u said. Then your values are right.
P.S.: A great tip for usb modems, if you have disconnections problems is to set in registry the "disconnectidletime" to 0, whatever it writes (independs by the modem, either 12 or 14 or 16 or 20 ) .
[HKEY_CURRENT_USER\RemoteAccess\Profile\YOUR ISP]
"DisconnectIdleTime"=dword:00000000
