[Wireless Router] Understanding Dual WAN Fail Over
Dual WAN failover is a network redundancy solution that switches to a secondary WAN connection to ensure uninterrupted Internet connectivity when the primary connection fails. This technology is particularly important for organizations and users who rely on the Internet for critical tasks such as data transfer, communication, and transactions.
Benefits of dual WAN failover:
Increased network reliability: Dual WAN failover ensures that you stay connected to the Internet even if your primary Internet connection fails. This feature is especially important for users who require continuous Internet connectivity to operate.
Automatic failover: Dual WAN failover provides automatic failover to the secondary WAN connection when the primary connection fails. This feature ensures that your network stays online with minimal interruption.
Customizable failover policy: Dual WAN failover allows you to customize the failover policy to suit your needs. You can adjust the detect interval and trigger condition for better experience.
Limitations of dual WAN failover:
Cost: If a dedicated network is prepared for dual WAN redundancy, it will increase the cost. If it is a temporary requirement, iPhone/Android phone can be connected to the ASUS router USB to serve as backup network. Wireless Router] How to setup backup WAN with Personal Hotspot/USB Tethering?
Limited bandwidth: Dual WAN redundancy cannot provide a way to combine the bandwidth of both connections. The maximum bandwidth is limited to the primary or secondary connection, depending on which one is active.
For the requirement of uninterrupted internet connection, dual WAN redundancy is a critical solution. When the primary network connection fails, it will automatically switch to the function of the secondary network connection to ensure uninterrupted network service. Before implementing this solution, the cost and complexity of implementing it need to be considered. If your router has a USB, you can connect your phone for testing first.
