Diagnostics
The diagnostics page is used to perform various diagnostics such as ping connectivity tests, trace route, DNS lookup and others.
Ping or Trace an IP Address
Ping: This utility can be used to test connectivity between this router and another device on the network connected to this router. Type in an IP address and click ping to send an ICMP echo request packet to the destination. If the destination IP address is active, you can see a response similar to “64 bytes from IP_Address: icmp……”. A “response timed out” message indicates that the destination is either not active or is blocking ping requests.
The results of the ping operation will be loaded in the current page. To return to the Diagnostics page, click on the back button of your browser.
Trace Route: This utility will display all the routers present between the destination IP address and this router. Up to 30 “hops” (intermediate routers) between this router and the destination will be displayed. An asterisk (*) is displayed for each intermediate device where there was no response.
The results of the trace route operation will be loaded in the current page. To return to the Diagnostics page, click on the back button of your browser.
Perform a DNS Lookup
To retrieve the IP address of a Web, FTP, Mail or any other Server on the Internet, type the Internet Name in the text box and click Lookup. If the host or domain entry exists, you will see a response with the IP address. A message stating “Unknown Host” indicates that the specified Internet Name does not exist.
The results of the lookup operation will be loaded in the current page. To return to the Diagnostics page, click on the back button of your browser.
Router Options
Display the Routing Table Click Display to display the internal Routing Table.
NOTE: An additional route entry with multicast destination 239.0.0.0 will be displayed when UPnP is enabled.
UPnP can be configured from Security --> UPnP menu.
Reboot the Router: Click Reboot to restart the router from the web interface.
Note: All active connections to the router and the connections going through the router to the WAN will be disconnected while the restart is in progress.
Capture Packets: Allows you to capture all packets that pass through the selected interface (LAN, WAN1, WAN2, or DMZ). To capture packets, select the interface and click Start. To stop the packet capture click Stop.
Note: The packet trace is limited to 1MB of data per capture session. When the capture file size exceeds 1MB, it will be deleted automatically and a new capture file will be created.
