Windows 10: Download speed limitation - desktop

Hi,

my desktop seems to be limited to +- 5MB/s if downloading from single source, when downloading from multi source i get full speed of my internet.
Other devices in my home does not suffer from this "phenomena".
Ive tried downloading on my:
phone - i get full internet speed.
notebook - wifi and only ethernet cable - full internet speed / what allows network card

Also checked my router if its not limiting specific device in this case my desktop, but its not - ive contacted even people on forum dedicated to that brand of router "synology" and i have ruled out that it might be issue with router.

I tried to disable FW, uninstalled several unneccesary SW from my desktop and still nothing.
I also tried via windows settings reseting network settings - it required reboot, and still nothing.
Also tried uninstaling LAN drivers and used these two from asus support page for my MB

Install Realtek LAN Driver.

Here are for example tests from same servers - speedtest.net T-mobile Prague server for Multi and Single
and you can see that limitation on these two pictures:








Can anyone think of something that might help?

Thanks a lot,

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

download speed is limited

hi there

I've been noticing a limit download speed which doesn't exceed 1.4 mb/s, it used to reach 5mb/s

if I download two files at the same time it splits the speed evenly

I updated my windows couple of days ago

 

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.
