Question
What tools can I use to test connectivity in my SBG6580-2?
Answer
The Diagnostics page in the SBG6580-2 includes various tools that are used for troubleshooting IP connectivity issues.  This document describes how to utilize the Ping and Traceroute functions.

This document contains the following sections:
Ping (Packet Internet Gopher) is a test used to check connectivity from the SBG6580-2 to another device on the Internet or the LAN (Local Area Network).  Using the ping feature, the SBG6580-2 sends a small packet of data to a device and waits for a reply from that device.  If the device replies, this confirms that the SBG6580-2 and that device can communicate with each other. 

Traceroute is another test used to map the network path from the SBG6580-2 to a remote device on the Internet.  This can be useful when a device fails the ping test.  If the device can be accessed, the traceroute test will display every hop taken to get to the destination.  If it cannot be accessed, the SBG6580-2 will display the last hop taken before the connection is terminated.  This is useful to pinpoint the location of a connectivity issue.

NOTE: Some devices are configured to block incoming ICMP (Internet Control Message Protocol) packets.  As a result, the ping and traceroute tests may fail, although the device itself is up and running.


How to Access the Ping & Traceroute Utilities
  1. Launch a Firefox or Safari browser.  Enter http://192.168.0.1 into the address box, and press the Enter key.  

    NOTEA browser message on Chrome, Edge, Firefox, and Opera, may appear when accessing the Web Manager.  The message includes 192.168.01 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH.  The Web Manager uses an earlier version of the TLS protocol and does not match the version allowed by the web browser.  Safari browsers on Apple PC and mobile devices are not impacted.  The workaround to access the Web Manager with a PC is to use the Firefox browser and set the TLS version to 1.  For workaround instructions refer to article # 19435 - 192.168.0.1 uses an unsupported protocol
     
  2. A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager.  There is no risk in proceeding to the Web Manager.  For instructions to bypass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.
     
  3. On the Login page, enter admin or a customized username in the Username field.
     
  4. Enter password or a customized password in the Password field.

    NOTE: On later versions of the SBG6580-2, the Wi-Fi Security Key is used as the default admin password printed on the bottom white label.  For assistance with Web Manager Access, refer to article # 18752 – SBG6580-2: Web Manager Access.
