SBR-AC1900P: Diagnostics Tool

• How to access the Ping & Traceroute Utilities
• Using the Ping WAN utility
• Using the Ping LAN utility
• Using the Traceroute utility 

Ping (Packet Internet Gopher) - A test used to check connectivity from the SBR-AC1900P to another device on the Internet or the LAN (Local Area Network).  Using the ping feature, the SBR-AC1900P 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 SBR-AC1900P and that device are able to communicate with each other.

Traceroute - A test used to map the network path from the SBR-AC1900P 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 SBR-AC1900P will display the last hop taken before the connection terminated.  This is useful to pinpoint where a connectivity issue is.

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.

The Ping WAN utility is used to check connectivity from the SBR-AC1900P to another device on the Internet.

1. Click the drop-down menu under Select Utility, and select Ping WAN.
2. Target - Enter the IP address of the computer to ping.
3. Ping Size - Enter the size of the data packet to be used for each ping attempt.
4. No. of Pings - Enter the number of ping attempts the SBR-AC1900P will send to the computer.
5. Ping Interval - Enter the time for the SBR-AC1900P to wait (in milliseconds) before sending each ping attempt.
6. Start Test - Click this button to start the ping test.
7. Abort Test - Click this button if it's desired to stop the ping test.
8. Clear Results - Will clear the information in the Results box below.
9. Results - The area below Ping Test Parameters, where the SBR-AC1900P will display the results of the test..
   
    

The Ping LAN utility is used to check connectivity from the SBR-AC1900P to another device on the LAN (Local Area Network).

1. Click the drop-down menu under Select Utility, and select Ping LAN.
2. Target - Enter the IP address of the computer to ping.
3. Ping Size - Enter the size of the data packet to be used for each ping attempt.
4. No. of Pings - Enter the number of ping attempts the SBR-AC1900P will send to the computer.
5. Ping Interval - Enter the time for the SBR-AC1900P to wait (in milliseconds) before sending each ping attempt.
6. Start Test - Click this button to start the ping test.
7. Abort Test - Click this button if it's desired to stop the ping test.
8. Clear Results - Will clear the information in the Results box below.
9. Results - The area below Ping Test Parameters, where the SBR-AC1900P will display the results of the test.
   
   

1. Click the drop-down menu under Select Utility, and select Traceroute.  
2. Target - Enter the IP address or Host Name of the destination device  
3. Max Hops - Enter the maximum number that the Traceroute operation performs before stopping.
4. Data Size - Enter the size of the data packets to be sent to the destination device.
5. Base Port - By default, this is set to UDP port 33434.  The default port is usually sufficient.  If desired, change this setting to the number of choice.
6. Resolve Host - Click the drop-down menu, and choose the desired setting.
         
   NOTE: Select On if it is desired to list the host name of every gateway (hop) used during the Traceroute operation.  Select Off if it is desired to list the IP address of every hop.
    
7. Click the Start Test button to start the Traceroute test.  The results of the Traceroute rest will display in the area below Ping Test Parameters, which is the Results section.
8. If desired, click the Clear Results button to clear the information in the results box below.
