A couple of years back, before the move to the COLO, we were having troubles downloading work units from the Science Lab.

Some networking wizard discovered that dramatic improvements to the speed could be gained by tweaking a few settings using TCPOptimizer.

Could someone please repost the settings or a link to one of the threads where this was discussed ? I need this information to (possibly) help resolve a connection issue I'm having with my ISP.

TIA

I think this is what your looking for , sorry I cant remember were the thread is for it but I copyied and pasted the instructions down and put them on a mem stick so I had them safe if I needed them again . I think the post was made by Richard Hazelgrove but the command line was by another person and Richard wrote the "how to"
Hope this helps you out

" Personally, I'd recommend the command prompt route.

You have two computers - one Windows XP, the other Windows 7. These steps will work on both, but note there is one extra instruction for Windows 7.

1) Open a command prompt:
Click on the Start button
Click 'All Programs'
Scroll down (if needed) to the 'Accessories' group, and click it.
'Command Prompt' should be visible...
On the Windows 7 machine, right-click on Command Prompt and select 'Run as administrator' - click 'Yes' for user account control. On the XP machine, just click the Command Prompt as normal.
You'll get what's often described as a black box on screen.

2) Run the command:
This is the text you need. Don't even attempt to type it: highlight it all here with your mouse, right click it, and choose 'Copy'.

REG ADD "HKLM\SYSTEM\CurrentControlSet\services\Tcpip\Parameters" /v "Tcp1323Opts" /t REG_DWORD /d 3 /f

Go back to the black box. Click on the miniature black box in the extreme top-left corner (the one with C:\... just visible in tiny print)
A menu should appear: go down to 'Edit' and select 'Paste'.
Press 'Enter' or the return key.
You should see "The operation completed successfully". That's all you need.
Close the command prompt window (the black box) with the corner 'X', or by typing 'exit'.

Restart you computer whenever it's convenient. You should see fewer downloads backing off and waiting to retry - though this isn't a total protection against all problems, and won't make any difference to the download speed while the transfers are actually running.

Let us know how you got on, and how easy it was to follow the instructions - they're a dummy run for the sticky I still intend to write.

Yup, that sounds like me, and it worked a treat for the problème du jour.

Which was network congestion, with the old line 'up the hill' to the Space Science Lab often running in the high 90s (% usage) for hours on end. It won't help in making a connection to a reluctant server. It's an official standards-based solution, enabled by default on Linux and similar other OSs, so there should be no detrimental side effects - whereas the original TCP optimiser program fiddled with a whole range of settings, which may or may not have been helpful on a particular link.

AFAIK, TCP Optimizer tool is just for up to Win7.

How about Win8.1 user, is there something to change for faster internet connection?

Thanks.

I'll throw in a curly one for anyone with Atheros Chipset Wifi on their host (in my case a cheap PCI express card, under some generic brand name). If you use modified drivers for the Atheros chip available from http://forums.laptopvideo2go.com/forum/128-atheros-chipset/ , then it exposes some extra (network adapter) settings that solve particular network problems with those. (afaik, these should work with vista onwards etc, though not tried other than XP and win7 OS variants for mine)

TA.

I think this is what you might be looking for.

Terror who is your I.S.P Optus ,DoDo , Telstra ?

What problem are you having ?

If optus and your just having slow speeds between about 11am and 12pm then it's just there network or you could blame the LNP and there fraud Band

If Telstra well bad luck

Same with any of the others till the Labour Party get back in and they finish the optical fibre network instead of the LNP's fraud band

@ Lionel
Ta. The second one was what I was after.

@ Glenn
I'm with Westnet. The problem seems to be a lack of capacity on the fibre coming into town. All ISP's seem to be effected, my Telstra wireless is dragging its feet and the Optus connection at work is only running half what it should.

They've just finished a lot of NBN work in Darwin and I'm wondering if they've pinched some of the bandwidth allocation from Alice Springs to boost the speeds up there.

Thanks to everyone else who offered advice.

Network speeds still suck up here.

I was shocked at the speeds my brother was getting in Byron Bay until I looked at his modem and found it was quoting over 10 Mbps achievable, but an actual rate of 1.5 Mbps. Seems that that is the plan he could afford years ago and he hasn't updated since. (And his ISP apparently hasn't told him that faster plans are now available.) Also his monthly limit of 3 GB peak and 5 GB off-peak would drive me doolally -- and I'm only getting 6 Mbps here (but unlimited data), I should change to fibre because it's strung to the telephone cabinet embedded in my front hedge!

Yeah, the sliding window and timestamps options (RFC 1323, what has been mentioned already) really only help to make connections more reliable across heavily-saturated, high-latency links. If you say the incoming fiber connection for the whole area is over-provisioned, then there's your heavily-saturated link that will cause problems. RFC 1323 won't make things faster.. just more stable.
