RV082 - Network Service Detection Broken

Network service detection keeps showing that WAN1 is down every so often and it is not.  I was running 4.2.2.08 and upgraded to the latest 4.2.3.7 and it still has the same issue. It is disconnecting our voip phones and other other connected software outside of our network. Has anyone else heard of an issues like this?

This is a remote office, I am

This is a remote office having the issues, I am now pinging the gateway the router is connected to in order to see any drops before our router.  I am doing this from my main office.  On the remote office router that has the issues, I did have NSD set to 4 for retry count and 5 for retry timeout.  These settings were below the defaults, which I think caused an issue so I put them back to 5 and 5, which are the defaults.  It seemed to behave better after making the change and ran with no NSD errors for a few days or so. However, I saw a WAN[1] down again yesterday.  I was using 8.8.8.8 to ping and changed it to opendns servers.  I did this because I know I had issues in a different location using 4.2.2.2, which was unreliable.  So instead of using google dns servers to ping I am going to see how opendns servers work.  When I did have retries set to 4 and 5 for retry timeouts, I would have around 4-5 disconnections a day.  Still hard to believe 8.8.8.8 would be down for 25 seconds though, but again, 4.2.2.2 became unreliable for NSD on another device so who knows.

Pinging opendns servers didn

Pinging opendns servers didn't fix the issue.  Does anybody else have failover working correctly on this device?
