Windows 10: Notice: Ethernet Adapter Speed reduced from 1.0GB to 100MB after July 2020 update Windows...

To: Microsoft Support Team

I would like to draw to your attention that after Windows 10 Pro 64Bit 2004 September updates, I encountered problem in reducing the Ethernet Adapter Speed from 1.0GB to 100MB Ethernet Properties – Networking Configuration; resulting reduction in Internet Bandwidth Speed to comply with the Ethernet Adapter speed reduction!



To temporally resolve this issue, I restored my PCs to July Updates, and PAUSED FUTURE UPDATES, in order to make the best use of maximum benefit of Internet speed subscription, until Microsoft resolve this issue.



Anticipating your immediate update action.



Regards…

IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Step 1:

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).


Step 3:

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs

 

Issues with integrated Ethernet and PCI-E Ethernet adapters


Hello,

Recently my on-board Ethernet port stopped working. At first I noticed that I no longer had the Wired Connection in the bottom right of my taskbar, instead replaced by the Wi-Fi symbol. I checked to make sure that my ethernet cable was plugged in, and that the lights on either side of the cable were blinking. They were. I then checked my Device Manager to make sure the driver was still there. It was. The only issue I could see was that my ethernet adapter no longer showed up in my network settings, only my Wi-Fi adapter was listed. I noticed in Windows Update, it mentioned that it failed to install a driver for a network component, so I decided I would look for the most up to date driver for my ethernet adapter online, and install it myself. Here is where the real trouble started; Every time I try to uninstall the driver for my ethernet adapter, including when I tell it to delete local files, it comes right back. I've tried disabling it first, and then uninstalling, and even completely disabling my windows update, and automatic device installer, but it still comes back every time. After a few hours of trying this with no luck, I decided to just run Recovery, and luckily it gave me a restore point to just before it ran the last Windows update. After recovery ran, everything worked, until I shut my computer off. When it booted back up, the ethernet adapter was missing again. Went through the same steps; Recover and wait. This worked, and I disabled Windows Update, and it has worked since. However, this fix isn't good enough for me. I want the latest updates from Microsoft, so I just decided to buy a new PCI-E Ethernet Adapter, and hope that would work better. I installed the card into my computer, and it didn't show up in my list of network adapters either, yet the driver for it shows up in device manager. I can also not uninstall this driver. What is wrong with windows? Why can I not delete a driver and just have it list the hardware under Other Devices as an unknown device? Is there some firewall setting that stops me from deleting drivers? Any help would be greatly appreciated.

 

Windows reducing ethernet speed and connection issues

Hello Andre,

The windows version is 1809, build 17763.475.

Disabling Energy Efficient Ethernet has had no effect.

I have also just tried connecting via a usb ethernet adapter, and windows set the speed to 100mbps straight away. (It was working at 1 Gbps on my laptop right before this with no issues)

There is no VPN enabled, and firewall being used is Kaspersky, but this is not the issue as I have already concluded from testing.

No bundled motherboard software was installed.
