Enable WAN Failover / Load Balancing in UniFi Dashboard

Enable WAN Failover / Load Balancing in UniFi Dashboard

1. Log in to your UniFi Network application (cloud or local).

2. Go to Settings ⚙️ (bottom left).

3. Navigate to:
   Internet → WAN Networks

4. You should see WAN1 configured already.

   • If you have a second ISP, click “Create New Internet” or edit WAN2.

   • Assign it to the secondary WAN port (e.g., WAN2, or a LAN port converted to WAN).

5. Configure the second WAN connection:

   • Connection Type → DHCP, Static IP, or PPPoE (depending on your ISP).

   • Apply ISP credentials if needed.

6. After saving, go back to:
   Settings → Routing & Firewall → Load Balancing

7. You will see two options:

   • Failover Mode → Primary WAN is used all the time, secondary WAN kicks in only if primary fails.

   • Load Balancing Mode → Distributes traffic between both WANs. You can adjust the weight ratio (e.g., 80/20, 50/50).

8. Select your preferred mode:

   • For Failover → Set WAN1 as Primary, WAN2 as Failover.

   • For Load Balancing → Enable and adjust weights.

9. Click Apply Changes.

Verify Setup

• Go to Dashboard → Internet and confirm both WAN links show connected.

• For Failover, unplug WAN1 and check if WAN2 takes over.

• For Load Balancing, run a speed test or check Traffic Stats to confirm traffic is split.
