Windows 10: Sudden large disparity between download & upload speeds.

(First post: Win 10 1809) Hello. I have encountered what seems to me to be a strange phenomenon: Recently upgraded to "1000 Mbps" fiber internet provider. Initial speeds for both download and upload speeds spread across the 900's, with upload speeds consistently a bit higher than download speeds. Yesterday one desktop seemed to have internet connectivity issues. I noted that the desktops Ethernet connection had for some reason adopted the name of one of our wireless routers: What had been "Network 2" was now "(SSID) 2".

This Dell XPS desktop (Win 10 Pro 64b, Version 1809) has both wired and wireless network connections, with the later used to connect to various peripherals. When I checked into Speedtest.net, Download speeds remained in the 900's, but upload speeds dropped below 50 Mbps. I went though various network troubleshooting steps and a number of restarts, this disparity persisted. Other than the lack of a name change to wired network connection, this disparity was also obtained on another desktop on the same network. However, speed checks on iOS tablet reveled no disparity whatsoever, suggesting that the phenomenon is limited to Windows machines.

Given my naive and limited understanding of Windows networking, I was hoping someone might help me to better understand the issue and, perhaps, suggest a fix.

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.
  

Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you

 

upload speed 5x faster than download speed

Your upload says 400kbps which is closer to like 50kb/s upload. So your download is still faster then your upload speed. Your download speed is more like 768kbps probably. What are your advertised speeds? Is it 768/400?
