Multi-WAN routers: A comprehensive guide to five of the best

Multi-WAN routers, as the name suggests, are routers that come with two or more WAN Internet ports so you can connect to multiple Internet ISPs. These routers are also called dual-WAN routers, especially when they have only two ports. Why should you go for these routers? Let’s take a deeper dive.

Benefits and uses of multi-WAN routers

There are a few important benefits that these routers offer over traditional ones.

Failover and backup

Multi-WAN routers are highly useful for those who need the Internet at all times and when even a few minutes of nonavailability can impact them in a big way. With multi-WAN routers, you don’t have to rely on a single Internet ISP only and this is a big advantage when you live in an area with a patchy Internet connection. These routers allow you to have an Internet connection from two different ISPs, so even if one fails, you still have access to the other.

You can even configure the first connection as the primary and the other as a backup connection so that the backup will switch over when the main Internet connection fails.

Load balancing

These routers also help with Internet load balancing so you can enjoy a reliable Internet service at all times. When you use many applications such as web browsers, VPNs, streaming services, and emails, you tend to use high amounts of bandwidth and the entire load is passed to a single ISP in a traditional router setup. But with multi-WAN routers, this load is spread across two or more ISPs, so the overall Internet speed tends to be faster.

Let’s understand this with a small example. Let’s say you have an Internet connection that gives 2.5 Mbit/second. Now, if you add another service that also offers 2.5 Mbit/second, you’ll have a total bandwidth of 5 Mbit/second and the load will also get split between the two ISPs. The same works in session balancing too, as the sessions are spread across many ISPs.

Such balancing ensures that you have access to high-speed Internet at all times, regardless of the load and size of applications that use it.

Security

Many dual-WAN routers come with L2TP VPN to help employees to securely connect to your network. Also, it allows you to encrypt traffic over public networks, thereby reducing the possibility of hacking or unauthorized reading of transmitted content.

Additional features

Some routers come with additional features that enhance their usability and performance. A few have a built-in DNS proxy, so users don’t have to define their own DNS providers while others have content-based and geo-based blocking services.

Overall, multi-WAN routers increase security, reliability, speed, and load balancing and through it all improves the performance of your router and gives you continuous access to the Internet at all times.

Now that you know what are multi-WAN routers, let’s take a look at some of the best ones, in no particular order.
