What is causing file Upload/Download to fail

Microsoft Windows 7 home premium oem 64b...
February 8, 2011 at 15:23:13
Specs: Windows 7, quad core intel 8gb
6 month old PC built with Windows 7 installed. Using Windows 7 Home Premium 64 bit. The problem I am having is uploading and downloading larger files to YouTube, Animoto and my Wordpress blog. I have NO problems using FTP, but when using any service to upload or download video files or large image files (I am a professional photographer), the process stops DEAD without ANY error message. It simply hangs up. I have had this problem for as long as I've had my PC - sometimes it takes 40 or 50 attempts to get things to upload/download, but I've run out of patience.

I tried using Google Chrome, disabling Windows Defender, disabling AVG anti-virus products, disabling Windows Firewall, using resumable JAVA download tool, using http download/upload tools with EXACTLY the same problem.

Do a quick search on this problem online and you return with hundreds (if not thousands) of the same errors, but I NEVER see an answer that works for my issues. I'm at my wits end - can someone put me out of my misery either with an answer or a bullet for this machine!? Thanks!!!

Have you thought of the possibility that the files are larger than YouTube or their server allows? Check their specs, FAQ's or check with their tech support on file sizes, picture sizes, or picture resolution.
Have you thought of using a program to convert the photos to a lower resolution format before you upload them? It will be easier, faster, and will make people pay for the higher resolution version. High resolution photos do not show up much different online, except when viewed on large HD TV's anyway.

You have to be a little bit crazy to keep you from going insane.

Thanks for taking the time to read and reply - I appreciate it. I am not uploading photos (as a photographer, I am familiar with web formatting and resizing in PS5), but HD videos UP to several services and DOWN from several services. The files are all within the TOS requirements for each respective service used.

The issue is somewhere within Windows 7 and/or IE8. The videos DO upload or download eventually (as I referred to when I mentioned that it takes up to 40 or 50 attempts for each file to successfully transfer). The fact that the files DO eventually work and the fact that I have used these same services in the same way for 3 to 4 years also indicates it is not a format or size issue with the files.

I have very limited access to a laptop with Vista and IE7. When I am able to use that laptop, 100% of the time (100% as in ALWAYS), the files upload or download preperly. I can't depend on a retro equipped PC to do the heavy lifting for my dedicated work PC.

The issue lies SOMEWHERE within Windows 7 and IE8 and I know from all the web rattling on this same subject that this is a VERY common problem. However, I cannot get the demons a MS to give me the "secret handshake" to fix it without paying them $45 per phone call.

I hope SOMEONE with experience in this same issue can tell me what switch to flip or which setting to change to get the problem corrected.

Thanks again for the response!

Just some random thoughts.

It's a bad idea to have more than one real-time scanner working. They run at deep levels and can slow down things. Pick one for real time and use the rest manually.

The problem is only with image files? Test a large executable and compare.

Check your network adapter's Properties sheet / Advanced for anything amiss. If it's Broadcom wireless, you can enable afterburner and xpress if they're there.

If it's wireless, check that you're on the best channel.

Maybe a different MTU setting would help.

One last thought - Opera allows increasing the number of simultaneous server connections.

Paul - thanks a ton for the reply!

I was using wireless, but gave that up for a direct ethernet cable connection early in this process. No wireless router involved.

Image files - NO

HD Video files - YES

These are all video, no images. They are all within the size limitations per the terms of service (TOS) of the service providers. The files are typically between 50mb and 750mb. I have successfully uploaded identically sized files for years - the problem only exists with Windows 7 and IE8.

All video files upload 100% of the time with Vista and IE7.

All video files fail 100% of the time with Windows 7 and IE8

I'm not familiar with MTU settings - maybe something I could try?

If packet size is too large, they start breaking up, slowing things down or preventing connecting. I've read where dropping from 1500 even to 1492 made the difference.

But I also wonder about Win7's default IPv6 protocol. It is known to slow things down, at this stage of Internet standards. Does the vista machine show v6 tunnels in ipconfig? If not, you could try disabling it in Win7 temporarily. Instructions here: http://support.microsoft.com/kb/929... Back up the registry key before changing, and reboot after each change.

Another thing is to make sure the router firmware is up to date, esp. with the switch to ip6. Or maybe a new router is in order.

I don't understand why the file content would be a factor, but this is to make sure all the basics are covered. If I were to try any of this, I would do the mtu thing last.

Thanks Paul. I truly appreciate the assistance. I'll work on some of the recommendations to see if they help.

Have you had a resolution on this. I have two 2008 servers at different locations and I am having problems downloading large files. It gets anywhere from 5 to 10mb and then times out. file cannot be found. Other PC's on the same network can download the files with no problems.

All these suggestions are great - if only they worked. It seems obvious to me that some of the respondants have not read the post properly.

Therefore, let's take an example. The BBC has video content on its website. Every video stops loading after just over 50 seconds. This happens on Internet Explorer, Google Chrome, and Firefox.

Youtube - Google's file server. Stops playing after about 1minute 30 seconds.

File downloads - stop after roughly the same length of time.

When is Microsoft going to admit that they have made a mess of this and fix it?

I am having this exact same probem with my notebook that is running Windows XP. I had no problem until 2 weeks ago when AT&T installed a new router in my home. First it started out just with wireless. So I connected directly to the ethernet cable and I was able to download, However I couldn't upload. Now as of tonight I can not download. I down loaded 2 files 1 144mb and one 99,b. Now I tried downloading another file 145mb and it starts and then stops after about 10mb and just sits there no error message or anything.

Very frustrating! I too have the same problem, as do lots of others, but I really have not seen a solution that would work for me. Here are some more clues as to why I think it is hardware related. I have this problem on my new Win7 build. I don't have this problem on any other computer - there are about 9 in the house - four others are running Win7 off the same wired or wireless router without problem. This problem computer is wired directly to the router. Also have a switch, it was plugged into. No difference, whether it was plugged into the switch or the router. I threw in a brand new HD and loaded Win7 , and still had the same error right away. Here is my hardware configuration: GIGABYTE GA-H67A-UD3H-B3, i7-2600K, G.SKILL Ripjaws Series 8GB (2 x 4GB).

This doesn't happen every time, but happens often. On YouTube, I can get it unstuck by switching resolution. With downloads, I can cancel, and restart.

It's a pain. Let's figure this out. I really want to hear from someone who has fixed this, and when I figure it out, I will post the answer - or email me at mbrenengen@hotmail.com

I have seen an answer from Microsoft where it is suggested that Adobe Flash be removed and reinstalled. I haven't done that as I don't think Flash is involved in downloading files, which, similar to downloading videos, fail. Also, his advice about a clean boot didn't work, as my new Win7 install was no different.


Please open Control Panel\All Control Panel Items\Programs and Features. Then remove the Adobe Flash Player. After removing, access the following website to download and install Adobe Flash Player.

What about the network drivers? That would make sense to me. Check out this post:


I did try recycling the router but that didn't help. Guess what (maybe) fixed the problem. Last night both my PCs received the latest Windows update. Now I have successfully downloaded the 1.6 GB file and am uploading another one. It could be something else but I did try two more downloads last night before the update ran and they failed. First thing this morning it sailed right through.

Thats because Windows updates also has updates for your drivers which is probably what the problem was. I never heard of recycling the router before, is there a cash redemption on those? If so I have a couple old ones laying around LOL.


Let me try that...

Well. For me, that seems to have done the trick. I went back to newegg, to the motherboard page, linked me to the GIGABYTE product page, where there was a new LAN driver, posted just a month ago. I installed that and watched several videos with no problems. I think it is fixed. Hopefully this will work for you too.

Think about it. It just make sense - because it was video and file downloads, FLASH is not going to do it. Because the rest of my computers work fine, it is not the router, switch or modem. Because it happened on a new install with no other programs loaded, it was not a conflict with a virus program or something. I had the same problem, whether using Chrome, Firefox or Explorer. It just seemed to decide it had had enough data, and shut down - like the LAN didn't want to work. I should have thought of that a long time ago...
