Upload Problems under Windows 10

[frosti323]

Hi,
Since updating to windows 10 (which was about a year ago) I have a problem with my upload on my computer.

The problem is that everytime I try to upload a file on googlecloud, gmail, twitter etc. I get an error message telling me it failed to upload. Same goes for other programs like outlook where it says failed to send email when I attach a file onto it.

When I try to do a speedtest (for example on www.wieistmeineip.at) the uploading progress bar goes about 1/8 of the way and then stops. On other speedtest sites (like http://beta.speedtest.net/) my upload seems to be working fine. The download is always working fine.

When I monitor my ethernet performance on the task manager while I upload or do the speedtests (on www.wieistmeineip.at) it goes up to 2-4mbit/s and after a second it drops down to 0 kbit/s.
On really rare occasions my upload seems to be working just fine, so that I can upload files everywhere, but for only a few minutes (10-30min), then it stops working properly. I can't figure out what triggers this.

I have already tried a lot of things to "fix" it but nothing worked:
Bought a new network card--> no upload.
tried the same lan cable and connection slot on my laptop (windows 7)--> working upload.
disabling my firewall--> no upload
tried a different lan cable /lan connection slot and also tried to connect it directly into the router--> no upload
tried formating my harddrives and reinstalling windows 10--> no upload
tried using different browsers (chrome, edge and firefox)--> no upload
updating drivers/bios--> no upload
using ubuntu live--> working upload
tried uploading files onto another computer in my homenetwork--> works fine


I really don't know that to do anymore and hope someone can help me.

Specs:
Windows 10 pro 64 bit
Motherboard: asus maximus hero VII
Internetconnection: 50/10 mbit/s

Who is your ISP? What service do you have - DSL perhaps? Make and model modem, router, modem/router?

Do you have access to the router's logs (if available and activated)? The logs may be capturing some error codes.

My ISP is T-mobile Austria. I'm using a Webcube (huawei e5170s) that goes into a switch, then into my pc. But I also tried plugging the ethernet cable directly into the webcube with the same results.
Unfortunately I can't post logs of the webcube, because it won't show logs (atleast I can't find them anywhere on the routher page)

The thing is that I had the same problem with a different ISP too. Back then I had DSL

Consider a firmware update:

Firmware is updated. Version: 21.236.17.50.54

This picture shows the ethernet performence (Task Manager) during two Upload Tests.
The upload goes up to about 3mbit/s for a second and then drops down to 0. Attaching files to an Email (on Gmail) also interrups after about a second.

Also if I use my phones internet on my pc via USB Tethering, my upload seems to be working fine.

UPDATE:
So I installed windows 7 64bit SP1 on a different harddrive on the pc and tried my upload with it... it still failed/same problem.
How can it be that only my pc has this problem and why does it only seem to be working with Linux?

Take a look at the Event Viewer logs.

May take some searching about but look for error codes or warnings that occur at the time of an attempted upload.

Might be some combination of events: i.e. a "perfect storm" situation causing the uploads to fail.

I found the problem!
My second ram stick caused the issue. When I took it out and only left one in my upload worked fine. When I switched the two my pc wouldn't even start.
They are: 16GB-Kit Corsair Vengeance Low Profile black PC3-12800U CL10-10-10-27.
Does that mean that the "faulty" one is damaged for good or is there any way to repair it?

 

[Ralston18]

You could inspect the module with a powerful magnifying glass and maybe spot something obvious.

Very unlikely to be end user repairable. Or even if so would require some high skill level (e.g., soldering) to fix.

Any warranty left on the faulty ram stick?

 

[frosti323]

I bought them two years ago and I think corsair has a life long warranty on their products, but their site is really shitty and i would have to send both of my ram sticks in. Also it would probably take atleast three weeks till I get new ones from them.

I'm thinking about buying just one new ram stick of the same type and replacing it with the damaged one.

Seems viable.

And at least you will be able to run on 8GB in the interim.

Match carefully.
