Turn Off Vista's Auto-Tuning to Prevent Browser Slow-Down
Posted by Kevin Purdy at 12:40 AM on April 18, 2008
Windows Vista includes a feature, "Receive Window Auto-Tuning," that you've likely never seen mentioned on your desktop, but which can cause noticeable drag and even crashing when browsing certain web sites or using some routers or other network hardware. If you're noticing browsing glitches that only occur in Vista, the Wise Bread blog has a tip, pulled from PC Magazine's recent issue, that explains how to turn off auto-tuning and skip the spinning blue circle of death.
The simplest way to turn off auto-tuning is to launch a command prompt as an Administrator (type "cmd" into the Start box, right-click on Command Prompt and select "Run as Administrator), then enter the following line:
netsh interface tcp set global autotuning=disabledThat should do it, and turning it off won't likely have any adverse consequences. If you find otherwise, turn it back on with:netsh interface tcp set global autotuning=normalHit the link below for instructions on see if auto-tuning (and a host of other TCP-type functions) are enabled on your system and learn a bit more about it.

Why should 'the average user' be expected to run commands to fix things which can cause crashes!? Surely this just proves that Vista isn't the best operating system for the average user.

Here's an explanation about what autotuning actually does:

@math0ne: Thanks for the link. Most of it was over my head, but it did explain some things. Most importantly, it tells you that disabling autotuning entirely should be your LAST resort, not your first. Their first suggestion might be the most useful, and the Wise Bread article skipped it entirely:
"First... check if your firewall or router can support window scaling... check for a firmware update that can fix the problem."

The link from math0ne is an important read if you want to understand what's actually going on.

Huhm. I've been using Vista for over a year with a Trendnet router as a NAT firewall, pulling 6-8 Mbps with no problems whatsoever. I suppose the 'Trendnet' part is the trick.

I'm still using Windows XP because it works without any problems whatsoever. Thought I'd wait until they get all the bugs out of Vista before I switch over. I also hate the new MS Office version (2007). I guess I'm just an old fashioned kind of guy :-)

CNN.com and Facebook used to run extremely slowly on FF 2 on Vista. It was as if the assets couldn't be downloaded. I would refresh or hit the URL again (GET request) and still nothing. After disabling the autotuning both CNN and FB fly using FF 2.
I'm not sure if this tweak has any effect on network file transfers, but that would be a nice side effect too.

@dangermoose:
Are you serious? Come on... is Linux any different with terminal commands? Is Mac OS X?
Heck, there are tons of things you can do in XP at the command line that can cause crashes. Just because you don't know about them doesn't mean they don't exist.

I have had problems with IE7 since I upgraded to Vista last year. Web pages, if they even load, appear after 45 seconds. This fix did not help. I can use Firefox with the IETab extension and pages appear instantly.

@math0ne: wow, that was informative. TCP is such an amazing protocol.
I would highly recommend reading that link... [blogs.msdn.com]
It has a link to specific incompatible devices and also a Microsoft connectivity test that will help determine if this tip is applicable to you.
If this tip does not noticeably help your network access, make sure you turn Auto-tuning back on.

@dangermoose: i'm not a huge fan of vista, but your comment shows a huge lack of knowing what the hell you're talking about.

@Babelfish: Most likely there's an add-on causing you problems. You should run IE without add-ons (there's a menu item for it in the start menu) and see if that solves the problem.
If so, you can enable/disable add-ons in the tools \ manage add-ons menu.

vista is a horrible OS, I will wait for the new one to come out in 2010. Although I have been hearing that some people are installing server 2008 saying that its what Vista should have been. XP is just solid and it runs. I don't think the harware was ready when Vista came out. I bought a new laptop 2 months after vista came out and it had the most memory, best intel processor, etc. Then the blue screens start. After about a year of "trying" vista I am done with it. I am a sys admin so I really use my PC.

Butbutbut I thought Windows "just worked"! One time dropping down to the command line is too many! How do they expect my grandma in Peoria to know how to do this?! Windows is not ready for the desktop!!!!!!

I really hate the sub-optimization or developer orientation in windows OS'es. But blaming it on Vista alone won't help; this kinda stuff will come in Win7 and do exist in XP...
As for vista, i felt that all it needs is a good graphics card and the graphics drivers -- my PC was an AMD 3000+ with 1GB RAM and 256MB GeForce 5500... But it ran as good as XP; and was intensely stable. I guess it differs from person to person, but IMO it's graphics that makes the most difference.

I got this error:
"Set global command failed on IPv4 The requested operation requires elevation."
I thought my user was an Administrator so I double checked the user account in control panel and sure enough it is an admin.
So why did this fail?

@biggunks: Did you right-click on the command-prompt and select "Run as Administrator"? The "Run as Administrator" part is important as in Windows Vista, if UAC is turned on, admin users still run with "non-admin" privileges unless the specific program is allowed through UAC.

OMG! Thanks!
Does this "little" problem have anything to do with the "I-can't-play-MP3-and-surf-at-same-time" problem?
