Windows 10: My internet upload speed over an ethernet connection is seemingly being throttled - how do...

My internet upload speed is seemingly being throttled when I'm wired-in over ethernet. When I run a speed test, I'm getting results in the neighborhood of ~90Mbps Down/0.2Mbps Up over fiber.If I'm connected to the Wi-Fi from the same router, I'm getting more normal numbers ~50Mbps Down/~50 Mbps Up.When I do a safe boot with Network, my upload speed over ethernet is also closer to what I would expect ~90Mbs Up. Given these items, I've eliminated anything outside of my computer as the issue, so I'm thinking there must be something running on a normal boot which is causing this - some program

Internet connection speeds

I'm really curious about this, considering the amount of hoopla every major internet connection provider likes to claim about their services, and many times exaggerated just to help their own sales . . .

So, with that in mind, anyone willing to post up their download/upload connection speeds, and we can see just how much of a difference there is in the various internet connection types.

Hit up Speedtest by Ookla - The Global Broadband Speed Test, choose the location closest to your home and begin the test, afterwards, copy and paste your result here. Also, please list what type of connection you have (dial-up, cable, DSL, VDSL, FiOS, etc) - if you are running through an ethernet connection, please also list whether it's a direct connection, or your LAN/WiFi connection speeds.

So, I guess I'lll start:

Verizon standard DSL - D-Link 802.11g 54Mbps

 

Weird - Internet Speed Throttling Issue

All,
I've noticed that I get really different speeds when speed testing through Cox's speedtest.net and through any other speed test (Fast.com, speedofme, etc.). Now, this would be just a weird anomaly, but I think it is affecting my wife's zoom webinars. For the past couple of months (after being rock solid for years), she gets an unstable internet connection in her zoom (and other webinars). When they are recorded, you can really tell the slow speed. I have a gigablast ONT from Cox, through a brand new RAX45 router (it did the same thing with the old router) to a Dell Aurora R7. However, this problem happens when I plug the ethernet directly into the ONT (by passing the router) AND when I try to use my wife's laptop (I connect it directly to the ONT or the Router and I get the same results). so, no router and it happens on two different computers. One weird thing is that immediately after COX reset the modem on their end, the speedtest.net speed showed blazing fast speeds, then 30 seconds later I get the throttled speed. This also happens occasionally when I plug in the ethernet into the new device (for example from the desktop to the laptop), the first speed test is normal, and then the second test is pool It almost like the modem is self throttling the connection - however, when I got to another speed test, is shows fast speed. I don't recognize a slow connection under normal use. Only with the webinars.
Right now, I just ran a speedtest on speedtest.net and got 46.5/0.37. The upload speed is crazy slow.
I had a cox tech here this morning who thought it was "weird" and suggested I called Cox and speak to a Tier 2 or 3 person. I spoke to a rep who worked with me for a little bit and then wanted to escalate it to a supervisor. She told me that he would be calling me. I didn't receive a call.
Another strange data point is that the throttling doesn’t seem to occur on my tablet or my phone. Speedtest.net still pumps out good numbers. Any ideas? I'm at a loss.....

As of today Desktop: Use ethernet connection, with Speedtest.net (either thru Cox website or the app), I get 40/0.6ish. With a USB/Ethernet converter to a 3.1 port, I get gigabit speeds. (When I plug in ethernet immediately after a modem refresh, I get gigabit speeds for the first speedtest I take, then it throttles back to the slow results.

Laptop (with only USB ports, so I use the same connector as above) - Get the 40/0.6 ish with Speedtest.net. Sometimes, when I first connect the cable, I get fast speeds, but it quickly slows down. Today, I actually got the 444.28up/0.37 down (I took a photo in case I have to show Cox). So, whatever is happening, it seems to be related to time.

 

WIFI Upload speed slow (throttled down)

WIFI upload speed is so slow on windows 10, 0.4 MB, compared to 3 MB when running on the same device from linux. The issue happens on 2 different devices, which rules out a device issue, and is running perfect from linux, which rules out a network or device
issue. Speed is fine when using a wired connection, and download speed is always good in all cases, 38 MB. Upload speed is fine when running tests from my android phone as well.

So the only situation where the upload speed throttles to 0.4 MB is when using WIFI on windows 10.

Solutions i've tried include DisableTaskOffload & "netsh int tcp set global autotuninglevel=disable", booting in safe mode, uninstalling-reinstalling drivers, resetting internet connection, updating windows, searching for drivers update in device manager,
and more.

Seems to be a windows 10 issue, trying to throttle down upload for some reason since it is happening on two different devices with different configurations, and as it is working fine on linux on the same devices.

Appreciate any feedback or proposed solutions.
