I encountered an issue where my internet experienced severe delays after installing Radmin VPN. If you by chance had the same issue: this is how you fix it.

1. Open the start menu
   If by chance you don't know what that is, it's the icon on the bottom left of your screen, click that.
   
2. Click the Cog Icon, that'll open your settings app
   
3. From there click "Network & Internet", it'll bring you a status page.
   
4. On the status page: Scroll down to "Advanced network settings"
   
5. Click "Change adapter options"
   It'll open a new window named "Network Connections".
   
6. On that page, right click the entry named "Radmin VPN"
   if you can't find it, look for an entry that says "Famatech Radmin VPN Ethernet Adapter" on the third line.
   
7. Click the properties option, it'll prompt you for Administrative Permissions.
   A new window will pop up, with "Properties" in the name.
   
8. In the pane below the text "This connection uses the following:"
   Click on the text of the entry "Internet Protocol Version 4 (TCP/IPv4)"
   DO NOT UNCHECK THE BOX, MAKE SURE IT'S CHECKED BEFORE YOU CONTINUE!
   
9. Click the Properties button, This should bring up a new window titled "Internet Protocol Version 4 (TCP/IPv4) Properties"
   
10. Look for the following boxes:
    "Preferred DNS Server"
    "Alternative DNS Server"
    DO NOT TOUCH ANY OTHER BOX OR SETTING!
    
11. If there are any numbers inside those two boxes, delete them now. Do not modify anything else.
    If there weren't any numbers there, then your issue is something else.
    
12. Click the OK button at the bottom.
    
13. Close all the other windows and check to see if your issue is resolved.
