Windows 10: Slow upload speed to any Microsoft services on Ethernet connection

I'm experiencing a really weird thing while uploading a file to any Microsoft services like Skype or OneDrive using my Gbps ethernet connection. The upload speed is limited to 2mbps only. When uploading to any other server e.g. youtube or any other website using the same ethernet connection, I'm getting the maximum speed that I supposed to get.Similarly, when using another 100 Mbps USB ethernet adapter or wi-fi connection to upload the files to the Microsoft services, I'm also getting the full upload speed.In summary:Gbps Ethernet adapter + Microsoft services = Upload speed is limited to 2 M

Slow upload speed on Ethernet Wired Connection.

I recently just reformatted my pc due to freezing problems. While that may have fixed it a new problem came around.

After reinstalling most of the drivers and essentials I went to check my internet speeds.

My current package deal is 30mpbs down and 10 mpbs up but my actual speeds right now is 30mbps down and
0.9 mbps up.

The device driver for the Ethernet connection is called : Intel(R) Ethernet Connection (2) I219V

I have tried several things so far:

• Turning off and on the router.
• Resetting the router to factory default
• Checking the if the Ethernet cable is faulty by plugging it into a different PC only to discover my upload speed was back to 10mbps on that other PC
  
• Uninstalling and reinstalling the ethernet driver
• Downloading the latest driver from Intel
• Turning off Windows Firewall (My only Anti-Virus atm)
• Found a forum stating I should disable "Large Send Offload V1" located in the Advanced tab of the device and enable the V2 but I only have V2 so I did not do anything.
  
• I have doubts its a virus as the only thing I downloaded besides windows updates is chrome.

So right now I am at a loss of what I should do to fix this. Since I learned that on my other PC I can get 10mbps upload but only on this particular one does not, I know there is something in the PC that is limiting the upload speed. I just do not know what
is causing it.

Any help would be greatly appreciated.

 

Slow upload speed

I have a cable service which is supposed to provide download speed of 300 Mbps and upload speed of 20 Mbps. My PC is connected to the service providers modem via an ethernet cable. I recently had a problem with both speeds being ultra low. A technician
visited and traced the problem to a broken copper wire tip on the input cable to the modem. He cut the end off the cable and crimped a new connector on. He ran some tests presumably to check that no other faults existed, reconnected the cable to the modem
and both speeds ran within the correct ranges.

The next day I decided to run a speed test and the download speed was fine but the upload speed was very low (down to 1.9 Mbps).

being curious I disconnected the infeed cable to the modem and checked the new connection. Everything looked fine so i reconnected the cable and ran another speed test. Both speeds were back up where they should be.

The next day I ran another speed test and the upload speed was low again. This time disconnecting and reconnecting the input cable to the modem did not resolve the problem.

Sorry for being so long winded here but my technical knowledge is rather limited and I prefer not to play with things I do not understand, but my question, "should I be concerned about the slow upload speed?" It does not appear to be causing any great problem
but the technician who visited did indicate that a slow upload speed could cause other problems with the modem, such as it automatically rebooting itself. This has occurred twice since the slow upload speed came back.

Other than going back to the service provider and waiting until they can send another technician out, is there anything I can do myself to resolve the problem?

 

Slow Download Speed

Hi,

Thank you for posting your query in Microsoft forums.

• I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
• I also suggest you to reset the wireless router to check if that helps.
  
• You may plug in the Ethernet cable if available and check the speed.
