Download stops in the middle

download fail in 20% - 30% depend on how big and how long time it goes.
Its downloading from ANY site.
Tried wireshark, i got:
But didnt know where to check... it seems fine. I got some TCP duplicate ack that marked as black..

but then the connection is gone. never shows again... even the downloading isnt finish

How long in time or bytes.

Is your disk full? (just imagine that is the right answer! I'll be amazed).

Also, this looks like a duplicate question to http://www.experts-exchange.com/Software/Server_Software/Web_Servers/Q_23937974.html

got 8gb left... well basicly nope.

true, but it didnt help me so i opened same question in diffirent group.

So how long in time and how many bytes do you normally get before the line is dropped.

Do you have any sort of local proxy server running? Is this interfering in some way?

Has it ever worked? If so, what was changed?

35mb stops around 19% 20%, we got no proxy server at all. Nope for me it never worked.

now downloading stop in the 19% and speed drop to 0 but after 10mins it start again, and it drops again...

Are you being throttled by your ISP?

Do you have a decent firewall to be able to see exactly who you are talking to?

when i did a TPtest its a tool to make fake trafic inorder to know the speed, it passthrough no problem.
You know if there is free tool to monitor the internet trafic i know the Ethereal and Wireshark, any that is better?

So, is it only when you download using, say, Internet Explorer?

What about using other browsers or even a PHP script?

Are you downloading complex archives which are being virus scanned?

What about a different user on the same machine?

I tried IE and firefox both same problemI didnt install any antivirus in my machine. But i never tried different user. will try it now.

I believe there's a download manager built into firefox to resume downloads...  if not, try one or more of these:

Free Download Manager - http://www.freedownloadmanager.org/download.htm
FlashGet - http://www.flashget.com/index_en.htm
GigaGet - http://www.gigaget.com/
ReGet - http://www.reget.com/en/
GetRight - http://getright.com/whatisit.html
GoZilla - http://www.gozilla.com/

Personally, I use GetRight... but I bought a copy of it years ago, before most of the others even existed. I have also tried Free Download Manager and it does a good job too. It actually does a better job of grabbing videos off youtube than GetRight does. It also converts them from FLV to other video types upon completion of the download if you tell it to. And it's free.  GoZilla was bought just about a year ago by the guy made GetRight, and completely rewritten, btw.

Darr thx for answering but i already know there are alot of download clients out there, this isnt very pratical to resuming it again and again.
 Press2Esc thx for the answering, i tried the ping to google with that command and it went through with 0% packets loss. Its working fine, however im kinda thinking if it could be the SP3 and SP1 in xp and vista tho. maybe something happend during the update that stops downloading...

A bit confused... I mistakenly was under the assumption that the problem was limited to 1 PC.   Perhaps, more specifics are in order.  For starters...

What is the website(s) you are having issue(s)?  If applicable, post your results from running a tracert to the url...
Is more than 1 PC experiencing the same problem?  How many total PCs are you running on the LAN?
What type of internet connection (e.g., dsl, cable, etc) do you have?
Does the download problem consistently fail or is it an intermittent failure?  
Is the download worse at specific times of  the day?

P2E

Company got 30 clients with 2 Vista rest XP, some got SP3 and him who got problem with download got SP1 Vista. The website im having problem with download is everything. well the download sometime didnt start right, stays in trying to connect and sometime connected but the speed drops to 0 kb/s and stay there for hours, happens all the time.
 

Are all his TCP settings appropriate (DNS, Gateway, etc.)

it set to DHCP on and i checked ya its right.

The problem is almost-certainly with that particular website. Someone would have checked it out and confirmed (or eliminated) that by now, but the needed information has not been forthcoming (Press2Esc directly asked what the website was in http:#a23226251).

 Sorry I'm still confused...  So, lets flip this one around a bit.   You stated, "The website im having problem with download is everything."  so does this mean that every site (e.g., google, yahoo, cnn, etc) that does NOT require you to DOWNLOAD a file works?  If so, this is a file xfer (ftp, tftp) issue.  

  Once again, what is the website(s) you are having issue, what application (browser, ftp client, etc) or command is being used when you encoiunter the trouble?

  Also, let me rephrase another one of my other earlier questions, can you download the file(s) from another PC?

P2E

Well this is problem exactly:
When i download from microsoft.com HP.com etc, the download goes from 200kb and drop down to 0kb.
I thought it was problem of switch or anything so i simply removed the network cable and connect to another computer just to try if the problem occure. the download went fine! no drop down at all, that was why i thought its computer problem, so i did a spyware scan and did a Hijackthis scan, everything seems normal... I also tried netsh log reset, also didnt help... so i tried to reinstall network card driver, still didnt help, reinstalled TCP/IP, nope still the same problem.  

Have you checked the firewall or AV settings.  Often on HPs site I've found that the download is actually using FTP and our firewall  (check the windows firewall, your AV suite FW and the external FW if applicable) wasnt allowing FTP.  The timer did start and moved to about 20%...guess thats when it actually realized that nothing was happening (however, in our case we never saw the 35mb.)  

On the AV, if its a suite, check that it doesnt have an intrusion detection piece thats interfereing.  If any IDP, IPS software sees you downloading a driver, executable, etc, it may bawk and drop the connection.  

This issue sounds like some security software or setting is dropping your connection.  (Could even be as simple as am IE setting...might try downloading firefox and try the download from the same machine with it...to rule out IE settings)

Well the download even dropped to 0 in safe mode of Windows, i kind of suspect the network card hardware issue, however this computer is old. Any tool to check network card healthy?

is this a broadband connection (dsl or cable)?

at the command line/window, try entering - netsh windsock reset . after a couple seconds it will ask your to restart your PC.

I too am having the same issue but on a home connection in a network.  Never had this problem before, I have all windows drivers updated.

its cable, fiber 10mbit, Phylox you got winXP SP3?
The netsh command should be "winsock reset" try that now and respond later on.

Nope it didnt help, around 21% of a 63mb file. the speed dropped down to 0. Anyway i will try to buy a new network card and see if it works better.

When the speeds drop to 0, I am wondering if you are still connected?  Try pinging your download site (ping downloadsite.com -l 1450 -n 50) a/o running a traceroute (tracert downloadsite.com) before and after you encounter a speed problem.

Also, when your session slows or goes to zero, try surfing to http://speakeasy.net/speedtest and confirm your systems connection & speed...  

If applicable, compare the results to that from another working workstation...

Tried Speakeasy.net/speedtest the connection dropps at 80% same issue there to Dallas server.

the connection somehow cut off at 80%... that could be the problem, but it also could be network card connection instable during the download?

When you are having problems connecting, enter "netstat -nb" at the command prompt and confirm that all the running programs are legit...  Once you verify the previous pgms, enter "netstat -anb" and verify all the listening ports are legit.  Basically, I am looking for excessive traffic (e.g., P2P, spyware/malware, hijack, proxy, etc)

Also, yo might to check your firewall log files or contact the ISP to confirm your sessions count is not excessive...

Welll the connection is  Established:
TCP 192.168.1.33:3711   15.193.112.29:21     Established
TCP 192.168.1.33:3712   15.193.112.29:40200 Established
TCP 192.168.1.33:3722   15.193.112.29:21  Established

Firefox got a error msg after awhile waiting: the source can not read. Download failed.

If you think its a hardware issue, download Knoppix or Ubuntu Live CDs and allow the machine to boot from CD.  If the issue is hardware, the linux flavor you chose will experience the same issue.  If it doesnt and all works fine, you can rule out hardware as the issue.  

very good idea, thx i totally forgot about livecd :) will try later and report the status.

Hmmm, you are definitely connected...  While I was unable to traceroute to the server (15.193.112.29), I was able to ftp into the server, but I did not recognize the commands

I am still thinking bacdwidth is saturated...  have you tried to access the file(s) in F8's "Safemode with Networking" option?  I suspect, it will work.

I already did, the safe mode didnt help too, the download still drops to 0 and i also tried the liveCD Slax, the download start first around 1sec, then it didnt download same issue. Hardware error? I was wandering if its possible that server block my IP adress to access?

The reinstall of TCP/IP i already did, not helping to fix the problem, update firmwire i didnt try yet, i will try that now, its network card buildin Mainboard, probably i need to update firmwire of bios and everything else. i will report a status when this is done.
