Testing and Troubleshooting Connectivity

To test your internet connection

  1. Reset your computer to use DHCP IP addressing and connect it to your LAN subnet or to the appliance X0 interface.
  2. Point your browser to the X0 IP address configured during initial setup (default: 192.168.168.168).
  3. Log into SonicOS using the configured credentials.
  4. In a command prompt window, type: ping sonicwall.com. You should receive a reply.
  5. Open another browser tab or window and point it to https://www.sonicwall.com or another valid web site. If the site displays, you have correctly configured your appliance.

To troubleshoot your internet connection

  • Verify that the Wireless Area Network (WAN) settings on your management computer are set to use either DHCP or a static IP on the WAN subnet. Restart it or renew the DHCP address.
  • Verify that the WAN interface being used for internet connectivity is not configured in Wire Mode or Tap Mode.
  • Restart your internet router or modem to communicate with the DHCP client in SonicOS on the appliance.
  • Check all cable connections and IP addresses.

To troubleshoot your MGMT connection, consider the following

  • Did you correctly enter the SonicWall NSA management IP address beginning with “http://” or “https://” in your web browser?
  • Did you try restarting your management station while it is connected to the appliance?
  • Are the Local Area Connection settings on your computer set to a static IP address on the 192.168.1.0/24 subnet?
  • Is the Ethernet cable connected to your computer and to the MGMT port on your appliance, and are the connector clips properly seated in the ports?

To troubleshoot your LAN connection, consider the following

  • Did you correctly enter the IP address for the SonicWall X0 interface into your web browser, beginning with “http://” or “https://”?
  • Did you try restarting your management station while it is connected to the appliance?
  • Are the Local Area Connection settings on your computer set to one of the following:
    • Obtain an IP address automatically using DHCP
    • A static IP address on the default LAN subnet (192.168.168.0/24)
    • A static IP address on the configured LAN subnet, if you changed it during initial setup
  • Is the Ethernet cable connected to your computer and to the X0 (LAN) port on your appliance, and are the connector clips properly seated in the ports?
