I am using at&t @home cable, here are the settings I am using. The main concern for me is I would prefer latency over bandwidth!! If that is at all possible. Mainly an online gamer and want to optimize my connection based on that!!

Also have PMTU discovery = 1, SackOpts = 1 Tcp1323Opts = 1


TCP options string = 020405b40103030201010402

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) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
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: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = OFF

Time to live left = 54 hops
TTL value is ok.
Note: Since TTL is decreased by at least 1 with each hop, the value above is equal to your TTL minus the number of hops to forums.speedguide.net

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000
Precedence (priority) = 000 (routine)
Delay = 0 (normal delay)
Throughput = 0 (normal throughput)
Reliability = 0 (normal reliability)
Cost = 0 (normal cost)


Tried this setting, but same result

PMTU Discorvey neds to be on:
Please go to this http://www.dslreports.com/front/drtcp.htmlRL
Download DR. TCP to your desktop
Where it saids adapter settings, select your adapter
Where it says Path MTU Discory select Yes
Reboot for changes to take affect

Do not change any numbers in this box unless you know what you are doing.
A blank box only means that the default setting is being used

You need to backup registry too if you have not, very important. here how:
First bring up REGEDIT, type REGEDIT in your run box and hit OK.
Under Registry at the top of the box, click on that, now click on Export Registry File, a box will come up asking where you want to export it to, just put it in your C drive, then name it at the bottem of box, Registry. Click on ALL at the bottom so it copies all of your registry.
Click on save.
Now if you ever get in trouble or want the old regestry back, bring REGEDIT back up and click on Registry and click on import registry file, go to your C drive and click on registry and click open, reboot and your good to go.
Anytime you add a new program, backup again, any program, back it up to the same place as the last one, it will overwrite it. If you do not backup after each new program is instaled you will not have those setting's in regestry if you have to backup for some reason.


Do nothing else in this box as it is the heart of your computer, just what it says above and no more!!!!!!!!!!!!!

I will leave you guidelines for speedtest, print these:
How do do speed test
1. The best time is early in the morning (3 AM - 6 AM)
2. Make sure defrag has been run so no files are fragmented
3. Delete Temp internet files, not while testing, but after each test. IE browser, click tools, internet options, click on delete files and no this will not harm system, just get rid of temp files
4. Go to a fast server such as www.happypuppy.com (http://www.happypuppy.com) and click on 10 demos, select a LARGE file to download (not all of it of download, just most of it, before you click cancel) this will show you how fast you are downloading, it's not going to be quick except except early in morning when not many people on net. I recommend you go to www.analogX.com (http://www.analogX.com) and download Net State live, run this while downloading as it will give you avg of your download speed.
5. Probably the most important, nothing can be running during test, no firewalls, no virus stuff, no ICQ, no AIM (some of you may have to go into BIOS to disable virus scanner, nothing running except Net Stat live
Scheduled tasks will run disk defrag, 98 & SE in Taskbar, WIN ME in control panel


Or if you wish you may go to www.testmyspeed.com (http://www.testmyspeed.com) and do one of the online tests, these vary to much for me but you may like them. Another one is at www.dslreports.com/tools (http://www.dslreports.com/tools) :)

Did some demo downloads from happypuppy.com and i would avg around 425-450, with a peak at a little over 500.

Well then, all seems fine, make sure to get faster loading of web pages from patch page, this site, follow instructions to install, and make sure registry is backed up :)

analog x shows avg of 475 and reached a peak of 685. I am happy with that!! Thanks for your help Lobo, MUCH appreciated!!!
