CDRouter 15.9

September 25, 2025

New Features

  • RF Attenuation over Package: RF attenuation can now be applied over entire package runs for more comprehensive testing scenarios. This feature utilizes the Range vs Rate (RvR) expansion. For more information, see the CDRouter Wi-Fi Range vs Rate (RvR) User Guide. [sc41768]

  • Sequence Diagrams: Packet captures can now be analyzed using a new sequence diagram view. [sc42085]

To view a sequence diagram, view a packet capture and click “View as” and select “Sequence Diagram”:

You can use typical display filters in the sequence view as well, such as filtering by protocol

You can rearrange hosts by dragging them, or click the “x” to remove them

  • DHCPv6 LAN timeout: Added new DHCPv6 test dhcpv6_pd_131 to verify valid and preferred lifetimes on the LAN are properly aged out. [sc9847]

  • DHCPv6 Prefix Delegation Router Lifetimes: Added two new DHCPv6 tests,dhcpv6_pd_16 and dhcpv6_pd_17, that verify when IA_PD lifetimes expire, Router Advertisement lifetimes advertised on the LAN are 0. [sc9825]
