Get Vista to Browse at High Speeds

by Karthik on August 3, 2008 · 95 comments

speed

I’m not a Windows Vista fan, but even then everyone at my home uses Windows Vista, while I dual boot with OSX on my Hackintosh.. I’ve used XP before and for some reason I always felt that Internet speeds on Vista were comparably slower than on OSX, and more so even Windows XP.

Considering it was quite slower than what I used to get on XP, I realized that Vista was doing something extra that made my internet connection slow down. After a bit of investigation and a bit of googling I found the solution.

Before I give the solution, let me explain the problem in a bit more detail’ It all comes down to Vista’s ‘Auto Tuning‘ feature. Turns out that this feature isn’t compatible with many routers and networking devices(including mine). Means the feature that was supposed to be a boon turned itself into some sort of a bane.

Anyways here’s what you need to do turn off the Auto Tuning feature on Vista..

At the Start menu type command, but don’t launch the command prompt immediately. Instead, right-click it and choose Run As Administrator. Once the prompt is open enter the following command.

netsh interface tcp show global

If the line Receive Window Auto-Tuning Level does not say ‘disabled,’ enter this command:

netsh interface tcp set global autotuning=restricted

If this doesn’t help, substitute this command and see if it works

netsh interface tcp set global autotuning=disabled

At this moment, you should notice considerable improvements in your browsing speeds, or rather you should be cruising now. If it works, you should notice the difference in browsing speeds immediately. If it doesn’t work for you, and you feel the need to put things back the way they were, you can type this command:

netsh interface tcp set global autotuning=normal

Here are screenshots showing the whole process, incase you feel the need for it..

Good luck, hope this works for you.. Please let us know if this worked for you or not..

Where is the donate button? Seriously.

This worked amazingly. I hadn’t even realised how dampened my browsing speeds were until this. My browsing speeds have been cut in half, at least.

Thankyou I have a vista laptop and a dual boot osx vista desktop…this was amazing how is this not a widely known hack? Is there any negative effects of doing this?

I chose the disabled command because I felt like it.

im not sure if this has worked for me ……… i have not been on your site for a week and im a fire fox user so i used your firefox hack at the same time as doing this and my internet speeds have boosted so im buzzing im not sure if its one or the other or both but something has worked

Cheers mate

I thought i would give this little Hack Attack a try on Vista Server 2008,but it alreadt set at normal. Just another reasons to convert Server 2008 into a workstation.

Reply

Jack August 9, 2008 at 10:06 am

@IANG

If it is set to normal then that means that is turned on. You want it at disabled I think.

What the Hell, It works, It really does. Eureka….
When will we be able to see a “humble” Vista workin with no need to hackin’ it??
Why Microsoft do this to us? I guess it’s just we don’t read between the lines, they want us to convert to Ubuntu.
The more I use Vista the more I miss XP, I swear if it did’t have Aero…

Hi

Half my browsing ground to a halt this morning. As did every other vista I know of around here.

This fixed it instantly.

Bizarre.

Well, no luck. For either suggested command I get an error message:

Set global command failed on IPv4 The requested operation requires elevation.

Since I have no idea what that means, guess I’ll live with the untweaked for now.

Thanks for the info though.

this actually, actually WORKS!! i’m always suspicious whenever i stumbleupon sites which claim that downloading this, or tweaking that, or messing with this will “speed up your computer”… and i honestly don’t know why i decided to risk it this time – maybe cos you had outlined a way to change it back in case it didn’t work and maybe all the comments – but i’m so so so glad i did.

it really does bloody well work!

the difference is actually noticeable, and not just if your a tech-head, even if your just someone who surfs on and off… trust me you’ll notice the difference. sites literally just “snap” on!

well done and big thumbs up… way up!

hmmm. no real difference here:
up/down on speed test:
normal = 9126/612
restricted = 9190/610
normal = 9211/612
not enough to tell if it was traffic at the time of the test or due to the settings. back to normal for me.

Chimney Offload State : disabled
Receive Window Auto-Tuning Level : highlyrestricted

None of the other commands worked. Command says “Set global command failed on IPv4 The requested operation requires elevation.”

I went to check this and found my hacked version of Vista (eXPerience’s TinyVista) already had this disable using yet another setting: highlyrestricted. It’d be interesting to see if this makes a difference opposed to restricted.

For all the “require elevation” issues, this fix requires you to run the command prompt as an administrator.
Remember to right-click on Command Prompt in the Start Menu and use “Run as Administrator”.

I feel that this wont increase download speeds either. So bandwidth tests won’t show the difference.
It seems to be more of a connection orientated fix, so a webpage with multiple objects and multiple connections will initiate the downloads quicker.
A single download stream will initiate quicker, but as its only one stream and long running it won’t be noticeable.

chiro February 8, 2009 at 7:21 am

Ok, I may be the only person who had this problem after this hack but I figure I should write about it anyway.

I am running a Vista 64Bit Vista Premium and shortly after I applied this hack, the computer simply froze. I did a virus scan and all the things we’re supposed to do but I came up with no results.

Vista went through its restore process and the everything seemed fine except for the last line that read ‘Auto Tuning Error In System Area’.

My system works fine now, but it gave me a headache beyond belief. I am not certain that this hack is the reason why it went crazy, but I didn’t make any changes other than this one.

With that said, I blame myself for doing something I didn’t need. I have 8 gigs of ram on this machine but for some idiotic reason, I thought I could totally have my browser speed be better.

Lesson learned.

PS. I am not trying to diss this hack in any way, but from what I gathered, Vista is still fragile and new to be tampered with.

Marcus Mangelsdorf February 16, 2009 at 1:36 pm

It worked for me, but the other way ’round:
Autotuning was set to “highlyrestricted” by default and turning it restricted or disabling it, didn’t show any effect – but setting it to normal really increased my browsing speed.

Anyway – Thanks for the great hint!!!

To the people having trouble with “Set global command failed on IPv4 The requested operation requires elevation”, elevation = Administrator (i.e. the UAC dialog prompt for elevation). In other words, you didn’t follow the directions. Left-click the Start menu, locate the Command Prompt (typically in the Accessories menu) and, while hovering over the Command Prompt, right-click. There should be an option to run that application as Administrator. You will be prompted to elevate the program prior to running it. Then try the ‘netsh’ commands again.

Greetings!!! I like this!! it worked!! I would like to have more of this as I would like to have more control over the Command line commands in Vista or any OS. I’m not only looking for stuff like this but i’m also looking for faster boot up speeds., so if you all can give me that? and accelerator speeds? then please Keep these tips comming. I would also like to change the Command line lettering to green. Can you tell me how to do that? Thanks.

Woohoo!! I feel all ‘techy’….a definite 1st.
For those of you who are as computer illiterate as myself, give it a go. Mine seemed to work after using the 2nd option. I didn’t see any improvement with the ‘restricted’ option but I can see the results now…I’m impressed.
And to the lovely author-I send many thanks for sharing your knowledge, it is appreciated.

When I did this, and re-checked the status of the Auto tuning, it remained unchanged, and below the diagnostics, it read “The above autotuninglevel setting is the result of Windows scaling heuristics overriding any local policy/configuration.”

What would cause this?

Great advice! I'm glad I Stumbled onto this.

If anyone has the message:

overriding any local/policy configuration on at least one profile.

It's a very simple fix.

Simply type in:
