We want to know if there is a way to run a 3G or 4G USB modem off the USB port on a Cisco 891W or Cisco 891FW as a fail over if the main bandwidth provider fails.
sorry i think that won't work
its primarily the embedded
but - since you did not mention the specifics of why
i was told the modem will support something different wifi eventually
and i found the note regarding the sierra wireless 4G/LTE
so i'm thinking you could possibly buy a different internal modem module
--Sierra Wireless MC7304 with Qualcomm MDM9215
