What Router/Solution from Peplink allows for Bonding? I was under impression from Marketing material that Balance 20 was capable?
There is an option using cloud. See Balance 20 WAN Bonding
For Balance series have a look at https://www.peplink.com/products/balance-series-comparison-table/ and about half way doen if shows the options for hot failover, WAN smoothing and Bonding.
For Mobile devices see similar table at https://www.peplink.com/products/max-series-comparison-table/
The Balance 20 can use two WAN connections concurrently and load balance between them. This happens out of the box and you get to chose assorted algorithms for the load balancing. Not sure if this is bonding, technically speaking.
If you want one router client to think they have a single pipe that is as fast as both WAN connections combined, that’s another thing.
In numbers, if WAN1 is 80Mbps and WAN2 is 30Mpbs, then out of the box any router client is limited to 80Mpbs. If you want a single client to be able to ruse all 110Mpbs, then its more complicated.
