Load Balancing Two Internet Connections

Load balancing distributes internet traffic across two WAN connections simultaneously, maximizing available bandwidth. Unlike failover (which only activates the second connection when the primary fails), load balancing uses both connections at all times. Peplink routers are well-regarded for multi-WAN load balancing — their SpeedFusion technology can bond connections and distribute traffic intelligently. Ubiquiti EdgeRouter and Cisco RV series also support dual-WAN load balancing. Configure the load balancing algorithm: Weighted Balance (allocate traffic proportional to connection speeds), Persistence (send related sessions through the same WAN to avoid issues with IP-sensitive services), or Round Robin. Important caveat: standard load balancing sends different connections (e.g., two browser tabs) through different WANs. This works well for most traffic but can cause issues with services that tie a session to a single IP (some banking and VoIP systems). Use persistence routing for specific destination IPs that require session consistency. Monitor both connection utilization to verify load is actually being balanced.
