Hi Jeffrey,
Apologies for the delay in responding to you. Moving your question under CMX Mobility Services API community for more visibility of the support engineers.
Thanks and Regards,

Jeffrey,
I believe that all Linksys residential routers are supported by Linksys. Cisco Systems may have supported a number of the residential routers in the past, but I do not find any support documentation on the Cisco site today. See the Linksys Community - Linksys Community.
