Yes, enabling load balancing will push both connections into an Active-Active state. Try to ensure you set your uplink speeds correctly as the load balancing feature will use the delta between WAN 1 and WAN 2s settings as a ratio for traffic management. Example WAN 1 is 100Mbs WAN 2 is 50Mbs That's a 2:1 ratio and thus 2/3rds of traffic will be pushed normally down WAN 1 and WAN 2 will take the remainder (unless there are other instructions to put specific types of traffic down one connection, or there's an outage.) Meraki wont split session traffic over 2 uplinks as well, so a voice call or download/upload will only use one connection at any one time, and not an aggregate of both. E.G. it doesn't make your speed 150Mbs but gives you that in throughput.
