    Resolve network issues


    You'll restart the machine at least once.
    Save any work, close open programs.
    Any unsaved work will be lost.

    The run command (WinKey+R or Run on Start) quickly gets you to Network Connections

    In the Run dialog, enter:
    ncpa.cpl

    After each suggested solution, see if the issue is resolved.
    If one suggestions fixes the issue, you do NOT have to do any of the other suggestions.

    1. Check the IP settings on your adapter(s)
      The settings below are preferred, unless your network has static addresses requirements
      Open Network Connections
      Right click on the affected adapter(s)
      Select Properties
      Obtain an IP address automatically
      Obatin and DNS Server address automatically


    2. Make sure the Network adapter is up to date
      Device Manager > Network adapters > adapter name
      Right-click the network adapter
      Select Update Driver Software > Search automatically

      If an update was found and installed
      Restart your machine

    3. If the adapter previously worked, try rolling back the driver for the adapter
      Device Manager > Network adapters > adapter name
      Right-click the network adapter
      Select Properties
      Details tab
      Select Roll Back Driver

      If the option was availble and the driver reverted to the previous version
      Restart your machine

    4. Run the built-in Troubleshooter
      Right click the network icon on the Taskbar
      Pick Troubleshoot problems
      Select Identify and repair network problems
      Press Advanced
      Select Run as Adminstrator
      Follow instructions in the troubleshooter

    5. Reset networking
      Launch Command Prompt (Admin)
      Copy the netsh and ipconfig lines below

      netsh winsock reset

      netsh int ip reset
      netsh int ipv4 reset
      netsh int ipv6 reset

      ipconfig /release
      ipconfig /renew
      ipconfig /flushdns

      Right click in the Command Prompt window to paste the commands

      Restart your machine


      If resetting the network to defaults doesn't solve the issue, use a bigger hammer
      Download delWinsock.zip

      Double click the zip folder to show the contents
      Double click delWindows.reg to merge into your Registry
      Note: The registry commands delete the Winsock and Winsock2 entries

      Then run the netsh & ipconfig commands above in Reset networking

      Restart your machine

    6. Disable IPv6
      Open Network Connections
      Right click on the affected adapter(s)
      Select Properties
      Scroll down to Internet Protocol version 6 (TCP/IPv6)
      Remove the check mark
      Press OK

      Restart your machine

    7. Reinstall TCP/Pv4
      Launch Command Prompt (Admin)
      enter the following commands

      netsh int ipv4 install
      exit

      Restart your machine

    8. Restart Your Network Adapters
      Open Network Connections
      Right click the affected adapter(s)
      Pick Disable

      Restart your machine

      Open Network Connections
      Right click the affected adapter(s)
      Pick Enable

    9. Turn off firewalls - for testing only
      Command Prompt (Admin)
      enter the following commands

      netsh advfirewall set allprofiles state off
      exit

      Visit TenForums.com

      Turn your firewall back on
      Command Prompt (Admin)
      enter the following commands

      netsh advfirewall set allprofiles state on
      exit

      If it turns out to be a firewall issue - update your software or contact the vendor

    10. Uninstall and Reinstall Your Security/Antivirus Software
      Also see Anti Virus (AV) stand alone removal tools

    11. Last resort (Win10 v1511 or greater)
      Command Prompt (Admin)
      enter the following commands

      netcfg –d
      exit
      Notes:
      NetSetupDeleteObject error - run netcfg -d until successful
      VPN clients, Hyper switches and other network software might need to be reinstalled or configured after running this command.

      Restart your machine

    12. Generate Wireless Network report
      Command Prompt (Admin)
      Enter the following commands

      netsh wlan show wlanreport
      exit

      The report can be found here:
      C:\ProgramData\Microsoft\Windows\WlanReport\wlan-report-latest.html
      Note: C:\ProgramData is a hidden folder, select hidden folders on the File Explorer View menu

      If members are assisting you, please copy the report into a compressed folder and attach it to your thread.

    Thanks for that awesome tutorial!

    Crossing fingers and toes and all other appendages that I won't need it with the new Win10 box.

    But excellent to know it's there, just in case.
    Thanks for taking the time to pull together those steps (I got lost reading the very long threads).

    Cheers,
