AI Verdict
This is a 5-port Gigabit Ethernet router with a dual-core 880MHz CPU and 256MB RAM, designed for wired networks where deep configuration is prioritized over plug-and-play simplicity.
This router is a situational fit because its powerful dual-core 880MHz CPU and 256MB RAM enable advanced networking configurations via RouterOS, but the lack of integrated Wi-Fi and complex setup process means it's not for everyone. It excels in wired-only scenarios where deep control is valued over ease of use.
If you need integrated Wi-Fi or a simpler setup experience, look for a router with a modern Wi-Fi standard (e.g., 802.11ac or 802.11ax) and a more consumer-friendly operating system.

Dimension Scores
It offers Gigabit Ethernet ports and IPsec hardware encryption at ~470 Mbps, providing high wired throughput for its price point, though routing with complex rules can limit full gigabit speeds.
Users consistently report stability and reliable wired connections, with MikroTik known for perpetual software updates and long-term support for its RouterOS.
The RouterOS interface is highly complex and not intuitive for average users, requiring significant networking knowledge and effort for initial setup and advanced configurations.
It includes IPsec hardware encryption at ~470 Mbps and RouterOS offers extensive firewall and routing protocols, providing robust security options for those who can configure them.
Best For
- Homelabs or small offices needing a powerful, configurable wired router without integrated Wi-Fi.
- Users with existing access points who need a dedicated, high-performance wired router.
- Network enthusiasts or professionals looking to learn and implement advanced RouterOS features.
- Environments requiring IPsec hardware encryption for secure wired connections.
Not Recommended For
- Average home users expecting a simple, plug-and-play setup with a graphical user interface.
- Anyone needing integrated Wi-Fi or a single-device wireless routing solution.
- Users with gigabit WAN connections who expect full line-rate routing performance with many complex rules, as it may cap out below 1Gbps with heavy filtering.
Watch Out For
- The RouterOS interface is not intuitive, and a single misconfiguration, like removing the IP from a port, can lead to losing access and requiring a factory reset.
- The reset button is deeply recessed, requiring a small, pointed tool like a wire to activate, which is inconvenient.
- Bandwidth management features might not work as expected, with some users reporting no change in tests after applying rules.
- OpenVPN implementation is limited to TCP, which can be slower and less efficient than UDP for some VPN use cases.
- The plastic casing may discolor over time, affecting its appearance.

What Buyers Say
What really stands out is how much control you get for the price, but you're going to earn it. People who are used to consumer routers will be completely lost in RouterOS, which is powerful but requires a deep dive into documentation or tutorials. It's a wired-only box, so don't expect Wi-Fi, but it handles heavy traffic and VPNs surprisingly well for its size and cost. Many users buy it specifically to learn MikroTik's ecosystem.
“Man, this thing is NOT for beginners, I spent hours just trying to get basic internet working, but once I figured out RouterOS, it's like I unlocked a superpower for my home network, totally worth the headache if you're into that kind of thing.”
Common Praise
- Handles multiple simultaneous traffic streams without lag.
- Offers extensive configuration options within RouterOS.
- Provides stable and reliable wired network connections.
- Low power consumption, typically around 3W.
- Supports IPsec hardware encryption for secure connections.
Common Complaints
- Configuration is too complex for basic home users.
- Lacks integrated Wi-Fi, requiring separate access points.
- LEDs are positioned on the top rear, making them hard to see.
- OpenVPN only supports TCP, not UDP.
- Some advanced features like bandwidth management can be difficult to implement effectively.
Ownership Tips
- The learning curve for RouterOS is steep, but there are many online tutorials and a dedicated community to help.
- You'll likely need to pair this with a separate Wi-Fi access point, as it's strictly wired.
- The device runs cool due to its low power consumption and passive cooling, even under load.
- Regularly updating RouterOS is recommended for security and new features, but it's not an automatic process.
- The microSD slot is useful for storing logs or 'The Dude' server data, but don't expect high-speed file transfers.
Frequently Asked Questions
Does the Mikrotik hEX RB750Gr3 have Wi-Fi?
No, the hEX RB750Gr3 is a wired-only router with five Gigabit Ethernet ports and does not include any wireless capabilities. You'll need external access points for Wi-Fi.
Is this router easy to set up for a beginner?
No, the RouterOS operating system is known for its extensive configuration options and steep learning curve, making it challenging for average consumers or beginners without networking experience.
Can I use this router with a gigabit internet connection?
Yes, it has Gigabit Ethernet ports and can handle gigabit routing and NAT. However, with many complex firewall rules, its routing performance might cap out below 1Gbps.
What is the USB port for on this router?
The full-size USB port can be used for connecting a USB drive for file storage, running 'The Dude' network discovery server, or connecting an LTE dongle for backup internet.
Does it support Power over Ethernet (PoE)?
Yes, it supports passive PoE-in on its first Ethernet port, allowing the device to be powered via an Ethernet cable from a compatible PoE injector or switch.
Buying Guide
When you're looking at a wired router like this, you're essentially buying the 'brain' of your network. It's responsible for directing all your internet traffic and managing connections between your devices. You need to think about how many wired devices you have, your internet speed, and how much control you want over your network settings. Don't confuse it with a Wi-Fi router; this one handles the heavy lifting on the wired side, leaving Wi-Fi to dedicated access points.
Gigabit Ethernet ports
This means each port can handle speeds up to 1000 Mbps. If your internet plan is faster than 100 Mbps, or you transfer large files between wired devices on your local network, you need Gigabit ports to avoid bottlenecks.
Dual-core 880MHz CPU and 256MB RAM
Think of the CPU as the router's engine and RAM as its workspace. A more powerful CPU and more RAM allow the router to process more data and handle complex tasks (like VPNs, firewall rules, or many simultaneous connections) without slowing down your network.
IPsec hardware encryption (~470 Mbps)
If you plan to use a VPN, especially for secure remote access, hardware encryption offloading means the router can encrypt and decrypt data much faster. This spec tells you the maximum speed you can expect for IPsec VPN traffic before the CPU becomes a bottleneck.
Alternatives
If this router doesn't fit, consider alternatives with integrated Wi-Fi for simpler home use, or models with higher CPU clock speeds and more RAM if you need to push multi-gigabit routing with extensive custom rules.
