My RV340W (latest firmware) is configured in multi-wan mode. One of the ISP's modem is an Arris DG1670. When this modem is plugged into the RV340, it experiences intermittent connectivity loss. A sample log reading of such a loss is as follows:

Practically speaking, the Arris DG1670, when plugged into the RV340, experiences random rebooting. When this rebooting occurs, the RV340 experiences loss of internet connection. Sometimes it freezes altogether and must be power cycled/rebooted.
However, the Arris DG1670 runs perfectly normally on its own (i.e., when it is not plugged in to the Cisco RV340).
I've been researching this issue but have not yet found a solution. I have also been working with the ISP's tech support team, who have visited my site 5 times now and have ruled out signal problems.
I'm lead to believe that there is a Cisco RV340 problem here. Has anyone seen this behavior before?
