EnGenius ESG510 Review: A Reliable Router

EnGenius ESG510 Review: A Reliable Router

Believe it or not, the EnGenius ESG510 is the second non-Wi-Fi router I’ve reviewed on this website. And like the Firewalla Gold, it’s a niche device designed for savvy/advanced users with a wired environment.

The hardware is Wi-Fi-ready, however. It includes a Multi-Gig 2.5GBASE-T PoE+ port best used for a Wi-Fi access point. I’ll emphasize that this router is not for everyone, and at the current street price of $600, it’s not affordable enough for anyone to try it out on a whim.

Here’s the bottom line: For a wired home or office where the Internet drop is not near the center — the case of many homes, unfortunately — the EnGenius ESG510 can be a sensible buy. It has Multi-Gig, security, routing, and VPN in a compact box.

So, if you want to build a serious Wi-Fi network using access points, consider this EnGenius ESG510 today.

EnGenius ESG510 Four Multi Gig Ports
The EnGenius ESG510 has four Multi-Gig ports. It looks more like a switch.

EnGenius ESG510: A simple yet sophisticated cloud-managed router

The EnGenius ESG510 is a rectangular box looking like a standard 8-or-fewer-port Multi-Gig switch. And with four Multi-Gig ports, it’s actually similar to a switch.

What makes it decidedly different is that its first port (label WAN1) is the designated default WAN port. Additionally, the second port (WAN2/P3) can work either as a LAN or a second WAN in case of a Dual-WAN setup. After that, the other two are LANs, of which the last one (P1) also supports the PoE+ standard (802.3at).

There’s also a USB port (WWAN) to host an optional backup cellular connection and a legacy console management port.

The table below shows the EnGenius ESG510’s hardware specifications.

The EnGenius ESG510’s hardware specifications

Limited local web user interface

The EnGenius ESG510 works right out of the box via its default setting if you only want a simple network. It’s preconfigured as a simple router with default standard settings.

The hardware setup is simple. Here’s how:

Connect the router’s default WAN port (WAN1) to an Internet source, such as a modem or a Fiber-optic ONT. Plug it into power, and mission accomplished!

Now you can add up to three wired devices to the router, one of which can be a PoE device or a switch to host more clients. And that’s all there is to do to get your network up and running.

In this case, the router has a local web user interface accessible via its default IP address,, with admin as the default username and password.

EnGenius ESG510 Web InterfaceEnGenius ESG510 Web Interface Local
The EnGenius ESG510’s built-in local web interface doesn’t allow much management.

Unfortunately, you can’t do much with this interface. There’s no way to change even the simplest settings, such as the router’s DHCP function. All you can do is configure the WAN connection(s) between a few common options and upgrade the router’s firmware.

So to make the router worth the hefty cost, you must use it via EnGenius’s Cloud portal, which enables you to customize it to the max.

EnGenius Cloud is a must-use

It’s straightforward to register the EnGenius ESG510 with an EnGenious Cloud account — the same account you’d use if you have other EnGenious Cloud Managed devices, such as the ECW336 access point.

All you have to do is create a free account at cloud.engenius.ai, sign in, and enter the router’s serial number in the Inventory & License section.

Alternatively, you can do that via the Cloud-to-Go mobile app, which makes the process as simple as using the phone’s camera to scan the QR code under the router.

After that, restart the router, and it’ll immediately become available via the web address above.

EnGenious Cloud has two access levels, Basic vs Pro. The former is free and generally has all most homes or office needs, whereas the latter requires licensing fees which vary depending on the situation.

No matter which tier you use, EnGenious Cloud offers access to all of the router’s settings and features, which include standard features (such as Dynamic DNS, port-forwarding, VPN), and more.

It’s worth noting, though, while the functions and settings of the ESG510 are similar to that of most standard routers, its interface is a bit different since it’s made for advanced users. That’s the case with all business hardware. There might be a bit of a learning curve.

EnGenius ESG510 Cloud PortalEnGenius ESG510 Cloud Portal DHCP
The EnGenious Cloud portal is the web user interface the EnGenius ESG510 doesn’t have locally. It has everything for the user to manage the router and their network(s).

Still, the idea behind the Cloud portal is convenience. You can manage multiple devices and even organizations in one place. For example, you can easily use two EnGenius ESG510 units for two locations, link them via VPN, and then manage both in the same account.

In return, your devices are always connected to EnGenius, which incurs inherent privacy risks. Here’s EnGenious’s Privacy Policy.

EnGenius ESG510: Reliable and fast Mulit-Gig performance

I used most of the ESG510’s features and settings applicable for a standalone office (or a home), and all worked as intended. There were no surprises.

Additionally, I tried it with a few PoE access points, including EnGenious’s own ECW336, and they all worked well. The ECW336 was the best option, however, since it’s part of the company’s Cloud-Managed family. The two proved to be excellent pairs, delivering a fast and reliable wired/Wi-Fi network.

EnGenius ESG510 Wired Network Performance
As a 2.5GBASE-T device, the EnGenius ESG510 delivered a fast and reliable wired performance.

Over more than a week of real-world usage, I ran into no issue with the router. The hardware remained cool, by the way, and seemed to have no internal fan — it was completely silent.

In terms of throughput, as a 2.5GBASE-T device, the router had the fastest sustained rates compared with all routers and switches of the same grade. That was impressive since it was the first router faster than standalone switches on this front.


Simple and straightforward to set up and use

Four Mult-Gig ports with Dual-WAN, PoE+ support

EnGenious Cloud Basic (free) has everything a home or SMB network needs with a helpful Cloud-to-Go mobile app

Compact, practical design; runs cool


A bit pricey; zero customization with the built-in local web interface

Online portals require a login account; no 10GBASE-T or SFP+ option

Requires some networking know-how to set up and manage


Again, the EnGenius ESG510 is not a router for everyone. However, it’ll make an excellent buy if you:

  • are looking for a non-Wi-Fi router,
  • don’t mind the required online account,
  • consider yourself an advanced user, and
  • want to build a Multi-Gig wired or Wi-Fi network via PoE access points.

That’s quite a big if, and that’s the point. This is a niche piece of hardware that, when applicable, will work out great. Evaluate your situation and maybe consider one today.
