This document explains how to test a store’s internet connection via Netgear LM1200.


PROCESS

  1. Go to the IT rack and find the Meraki and the Netgear 
    • NOTE: Both are usually located on the top shelf
  2. Make sure the Netgear is connected to Meraki Firewall on port Internet 2.
  3. On the Meraki Firewall find the Cat 5 cable (usually a yellow cable) connected to Port Internet 1. 
  4. Unplug it.
  5. Go to the manager’s PC and open the Command Prompt 
    • Search “Command Prompt” in the search bar by the Windows icon.
  6. In the Command Prompt window, type “ping 8.8.8.8 -t” and press “Enter”.
  7. This will generate “Request timed out” error messages. 
  8. After getting the error messages, let the command run for about 10 minutes. 
  9. The Netgear should start up automatically and a message similar to the one below should show.
  10. This confirms the backup internet is operational and a solid white LED light should be on the front of the Meraki Firewall
  11. Go back to the computer rack and plug the Cat 5 cable back into the Port Internet 1 on the Meraki Firewall. (Yellow Cable)
  12. Return to the manager’s PC and make sure you are still getting a reply in the command prompt. 
  13. If you are, perform a Google search to confirm the store has internet (e.g., Google “Mister Car Wash”).
  14. If the reply in the command prompt still shows “Request timed out”, make sure the Cat 5 cable is plugged into the Port Internet 1 on the Meraki Firewall. 
  15. If this doesn’t fix the issue, contact Mister IT.
  16. Close the Command Prompt app.
