If you have confirmed the firmware version, a new page with

firmware update progress will be displayed next. There are no

functions available on this page, just information about the

firmware update procedure. At some point the connection

with the device is being lost and you need to wait until the

firmware will be burned on the Quadro.

You will not be automatically redirected to the Login page. To

access the Quadro’s Web GUI, you need to connect Quadro

again and login.

Networking Tools

The Networking Tools page provides the possibility to check the Internet connection.

Ping sends four ICMP (Internet Control Message Protocol) requests with a default size of 64 bytes to the destination (IP address or host name)

specified in the text field Ping Target. The response times are logged, and the round trip time (the time required from being sent until being received

again) is measured. The minimum and maximum round trip time and its average as well as the percentage of lost and of received frames results are

displayed in the lower area of the page.

Traceroute checks the Internet connection by triggering the routers (hops) that are passed to reach the destination specified in the Traceroute

Target text field. Trace routing gives feedback on the routers passed by packets on the way toward the destination and the round trip delay of

packets to these routers.

Attention: No Traceroute is possible if a high priority Firewall has been enabled (see chapter

Firewall and NAT).

For the purpose of tracerouting, several IP packets are sent

out. UDP (User Datagram Protocol) is used to send packets

and ICMP (Internet Control Message Protocol) is used to

receive information about the routers. In their headers, the

TTL (Time To Live) value increases from 1 to 30. When the

first IP frame is received by the first router, its IP address will

be returned in its acknowledgement

The second frame delivers the IP address of the second

router and so on and so forth. The results of Traceroute are

displayed on the lower area of the page.

Ping Target requires the destination (IP address or host

name) for the ICMP request.

The Ping button starts pinging the specified ping target.

Traceroute Target is used to enter the IP address or host

name of the destination to be trace routed.

The Traceroute button is used to process the router

triggering to check the Internet connection.

In the field below these, the output of the Ping or Traceroute

procedure is shown.
