I just installed a new Balance One router yesterday. Today my monitoring system notified me that it went offline at 5:00am (which meant I had to get up and make an early one-hour drive to reset it).
After checking the event log, I discovered the following:
[TABLE=“class: stat_table, width: 744”]
Nov 26 04:55:59
WAN: WAN 1 disconnected (WAN failed DNS test)
Apparently, it was unable to ping the DNS server and took itself offline.
Since I only have one WAN connection, there was no way to failover to WAN2. It remained offline until I reset it.
WAN1 is configured with a static IP and WAN2 is disabled.
I disabled the health check to avoid this problem in the future. However, this does not seem like the most intelligent default response to a failed health check on a single-WAN system. This means that a temporary network glitch will cause the router to go offline.
Is there a good reason for this kind of behavior or is it a bug?
