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.
