Slow internet connection on Vista?

We use WinInet to send HTTP request and get response. On Windows XP, it works fine. However, I got timeout error on Vista. The timeout occur when calling InternetReadFile(). I tried many times. Sometimes, It works; Sometimes does not. My Vista version is RC1 build 5600.

I am not sure this is a Vista bug or we did something wrong. Please help.

Would you be able to send a code sample?

Thanks

Run following command from Admin-level command line prompt solved the problem. I think Microsoft will fix this problem. Is that right?

netsh int tcp set global autotuninglevel=disabled

Hello Jigsaw-ols,

I have found that this has been addressed a few days ago and should appear in the RTM product. For now you will just need to use the netsh workaround.

Thanks,

Yes, netsh solved my problem. Thanks!

I have a brand new machine with 4Gb RAM and a 5Mbps connection, running Vista ultimate and the internet is soooo slow (I also have an XP Pro desktop and laptop that use the same router and they "fly"); what in Vista is causing the internet to be slow?

I've tried the netsh solution (no change); I've also tried disabling IVP6 (that stopped the entire connection from working on the Vista machine).

Anyone any ideas? Google seems to reveal hundreds of posts about slow internet, but none that give me a solution.

have you figured out what was causing the slow internet speeds? I have the same problem and am looking for a solution...

Nope, not a hope

I'm close to installing XP Pro on a brand new "Vista" machine :-(

Finally cracked it (after switching off IPV6); turns out culprit (for me) was McAfee

Uninstalled and now she flies ;-)

Hope this helps others

After numerous hours on the phone with my manufacturer (downloading patches, resetting the machine etc), we finally discovered that the problem was indeed McAfee. More specifically, it was the Phishing Filter. Both IE7 and McAfee have Phishing Filters, which I dare say is too much 'protection' for anyone's party. Once I disabled the McAfee filter (but left the IE filter running) we were off to the races. I just had to go back into McAfee to disable the annoying messages that I wasn't fully protected. Hope this helps.

Have tried just about everything there is to try.. do not have Macafee, or I'd be disabling that. Anyone else? Same issues here - brand new computer running vista - can take up to a half hour to load some pages. Downloading anything right now isn't even an option..

Exact problem as robg2251. I've disabled IPv6, went to services.msc and set the IP Helper service t omanual (not sure what it does, but if I encounter any problems I'll set it to Automatic again). My download speeds are incredibly slow, and I want to download a lot of things but with Vista I don't think it's going to happen any time soon.

EDIT: I came across this topic by googling. So far, I haven't found much, but I've learnt a lot. If I ever get a solution, I'll be sure to post it.

I can confirm that turning the McAffee phishing filter cured it for me where all the other fixes failed. NOTE turning it off in the main Configure box did not work but the setting in the "Internet & Network" tab did... From some posts I had read I thought I was going to need a new router but this Vista machine is now as good as the XP one through the same old DSL 504T router.

Hope that helps someone, it has just wasted about 5 hours for me getting this new PC to work. and I don't think I would have done it without this thread so many thanks to everyone else.

After much research I figured out Vista SLOW internet connection problem! Just simply uninstall the McAfee program and you will see that the internet connection will fly and I mean fly!!!!!!!!!!!!!!

I don't have McAfee on my system (and never would! it's pants) but still onlky getting about 25kbs download speed from an 8Gig broadband service! Under Xp i'd be averaging around 500kbs! Why is it running so slow, if it doesnt have McAfee installed? Its such a pain the @rse when trying to download 40gig+ driver files etc! Takes sooooo long!

I've tried using my USB modem and my Netgear Router. Both connections give the same slow speeds!

Please, Microsoft, help! Otherwise I'll be returning my Vista and putting my old Xp Pro back on which ran fine!
