WAN smoothing with Peplink means that the data is transmitted redundantly over several lines. Depending on the smoothing mode, this ranges from double to the number of WAN connections.
However, if the stream still has connection interruptions, there may be several reasons for this.

1. The hub must be connected via a stable internet connection. We strongly recommend a hub in a data center. You are welcome to host these streaming-optimized VPN hubs in our data center.
2. If no line is available at your location, or if all lines are so poor despite redundancy that the same data packets are lost on all lines at the same time, then the router can no longer compensate for this. However, this case is fortunately rather rare in practice. In this case, it can help to switch off WAN smoothing and switch to bundling mode and reduce the bit rate of the encoder.
