Windows 10: internet upload speed

I have 300mbps download on Ethernet but only c4mbps upload.

What could be limiting the upload speed?

My Dell laptop has a Qualcomm QCA1565 adapter

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.

 

Upload Speed

Hi

I was wondering why my upload speed was .92 or .70 and i want to fix it so does anyone have any suggestions to fix my upload speed?

By the way i live in the wide country and i was wondering if that had anything to do with that.

Thanks

 

Fluctuating Download/Upload Internet Speed - up to 50% less

Hi there. I'm trying to troubleshoot my friend's internet speed that goes from ~150-375 Mbps download and ~15-37 Mbps upload. She's paying for 400/40 and the internet repairman said the speeds going into the modem are fine. She's directly connected (no wi-fi)
and the normal speeds are around 220 down/25 up.

The network card has the latest driver (tried uninstall/reinstall), and I've tried some other things (listed here: Top 4 Ways to Fix Slow Internet after Windows 10 Update | Driver Talent), but it doesn't seem to make a difference.
If it does, the proper speeds don't last long so it just could be a coincidence. I know there is always fluctuation in speeds, but over 50% sometimes is too much.

Thanks.
