Starting Up the Modem
It is advisable to run Wireshark during the start-up and configuration of the modem
in order to ascertain the correct execution of this process and diagnose potential
configuration problems.
The first sign of life exhibited by the modem is the Spanning Tree Protocol (STP)
packets. After a few STP packets, the modem will issue a DHCP discovery packet,
as shown in Figure 1.

If you cannot see the DHCP packets coming from the modem, the possible causes
include:
• The firewall is filtering out these packets
• You are not running Wireshark on the physical Ethernet interface
• The adapter does not have the factory-default configuration
• The adapter is booting in NVRAM mode and is set with static IP settings.
Note:
In order to see the DHCP discovery, Factory reset is suggested.
