If you’re experiencing difficulty with the RV016 version 2 supporting dual WAN in both load balance and backup modes with logs, download the latest firmware V3.0.2.01-tm. This software upgrade ensures both WANs can function simultaneously in load-balance mode and that the backup WAN goes up when the primary WAN goes down when in backup mode.
