Dual-WAN Setup Guide: Never Lose Internet During a Meeting Again

Redundancy is Luxury

Imagine this: You're presenting to a client, and a construction worker cuts the fiber cable outside your house. Show over? Not if you have Dual-WAN.

Failover vs. Load Balancing

• Failover: You use your primary connection (Fiber). If it dies, the router automatically switches everything to the backup (5G/Starlink) in seconds.
• Load Balancing: You use BOTH connections simultaneously. A download might be split across both lines, effectively doubling your bandwidth (in theory).

Hardware Requirements

You need a router with dual WAN ports. Brands like Ubiquiti (UDM Pro), Mikrotik, and Synology offer excellent Dual-WAN support. For the secondary connection, a simple 5G T-Mobile Home Internet box or a Starlink dish works perfectly.
