Windows 10: how can i fix the 10mbps cap issue on the Realtek Gaming 2.5GbE Family Controller?

I have a in my b660 gigabyte motherboard and im currently experiencing an issue regarding my link speed and download speed being capped at 10 mbps even if i changed my duplex speed to 100mbps and can reach higher speeds on other devices, i have tried updating drivers, manually changing duplex speeds, disabling EEE, everything yet my speed is stuck on 10 mbps and download speed on 1.2mbps at best, nevermind the ip authentification issue that doesnt allow me to connect to the internet only after multiple and multiple tries. And yes it is a custom built pc not a OEM.

Realtek PCIe GBE Family Controller - fixed!

Any plans to fix the driver issues with Realtek PCIe GBE Family Controllers?

Looks like there are lots of people having issue with the Realtek GBE drivers.

Just found the post below and it fix my issue:

If you have unsupported VPN software installed on Windows 8.1 when you upgrade, you may encounter this problem.
We are currently working on a fix. To check if this is causing your networking issue:

• 
  Right-click the Start button and select Command Prompt (Admin).
  
• 
  Type the following command in the window and hit Enter:
  
  netcfg –s n
  
• 
  This will show a list of networking protocols, drivers and services.
  Check to see if DNI_DNE is listed in the output.
  If it is, this problem applies to you.
  
• 
  If DNI_DNE is present, in the same command prompt window, type the following commands to resolve the problem:
  
  reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f
  
  
  
  netcfg -v -u dni_dne
  
• 
  If you receive the error 0x80004002 after running this fix, either the register key was not deleted or the key that needs to be deleted is slightly different.
  Open Regedit and navigate to the key: HKEY_CLASSES_ROOT\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3}.
  Delete it if it still exists. If it is not present and you still received this error, please reply to the post.
  We may contact you to help identify the cause of this error.
  

If this resolves your issue, in order to use your VPN, you will need to contact the manufacturer of the VPN software to obtain a version that is supported for use on Windows 10.

Please be aware that there are many possible reasons that a wireless network might not be available.
If this does not resolve your issue, make sure you’ve tried the general troubleshooting steps provide in

Windows is updating my Realtek - LAN - Realtek PCIe GBE Family Controller driver everyday to the same version

Hi,

There are several factors that can trigger a certain driver on your computer to update from time to time with the same version. One of these is due to system file corruption. For us to effectively assist you in rectifying the unusual activity of the Realtek
PCIe GBE Family Controller driver, we'd like to know these details:

• Did the issue happen right after you installed the Creators update? If yes, may we know how you acquired or installed the update?
  
• Is this behavior confined to the Realtek Family Controller driver only?
• What steps have you done so far to resolve the concern?

Your reply is highly appreciated.
