MikroTik hEX RB750Gr3 – 5-Port Gigabit Ethernet Router
MikroTik hEX RB750Gr3 is a compact wired Ethernet router designed for homes, small offices, branch networks and professional network installations that do not require built-in Wi-Fi. It provides 5× Gigabit Ethernet ports, a dual-core 880 MHz CPU, 256 MB RAM and a USB 2.0 Type-A port, making it a flexible platform for routing, firewall, VPN, VLAN and network management applications.
The hEX RB750Gr3 runs MikroTik RouterOS and is built around the Qualcomm Atheros QCA9558 processor. Its compact desktop enclosure and passive cooling make it suitable for installations where a small, quiet and dedicated wired router is required.
5× Gigabit Ethernet Ports
The MikroTik hEX RB750Gr3 features five 10/100/1000 Mbps Gigabit Ethernet ports. These ports can be configured through RouterOS for WAN, LAN, VLAN, bridge and other network functions.
A typical setup can use one Ethernet port as the WAN connection while the remaining ports provide LAN connectivity. However, RouterOS allows the ports to be configured according to the requirements of the network rather than restricting the device to a fixed WAN/LAN arrangement.
Dual-Core 880 MHz Processor
The hEX RB750Gr3 is powered by a dual-core 880 MHz QCA9558 CPU. Combined with 256 MB of RAM, the hardware provides a dedicated platform for MikroTik RouterOS features including firewall configuration, routing, VLANs, bandwidth management and VPN applications.
Actual routing and VPN performance depends on the configuration, enabled features, packet size, traffic pattern and whether hardware acceleration or other RouterOS optimizations are available for the selected function.
RouterOS for Advanced Network Management
The RB750Gr3 runs MikroTik RouterOS, providing a broad set of networking functions in a compact wired router.
Depending on the configuration, RouterOS can be used for:
- WAN and LAN routing
- IPv4 and IPv6 routing
- Firewall rules
- NAT
- DHCP server and client
- VLAN configuration
- VPN connectivity
- Bandwidth management
- Queues and traffic shaping
- Bridge configuration
- Static and dynamic routing
- Network monitoring and management
USB 2.0 Type-A Port
The hEX RB750Gr3 includes one USB 2.0 Type-A port. The USB interface provides additional flexibility for supported RouterOS applications and compatible USB peripherals.
USB functionality depends on the connected device and RouterOS support for the specific peripheral.
Compact Wired Router for Small Networks
The hEX RB750Gr3 is designed as a wired-only router. It does not include an integrated Wi-Fi radio, which makes it suitable for network installations where wireless access points are deployed separately.
This architecture can be useful when a network requires a dedicated router combined with one or more independent access points. It allows the wireless infrastructure to be selected and upgraded separately from the routing platform.
Passive PoE-In
The MikroTik hEX RB750Gr3 supports passive PoE-in on Ethernet port 1. It accepts a DC input range of approximately 8–30V and can also be powered through the DC jack.
Passive PoE should not be confused with IEEE 802.3af/at active PoE. The power source should be compatible with the hEX’s specified passive PoE voltage requirements.
Passive Cooling and Low-Power Design
The hEX RB750Gr3 uses passive cooling, allowing it to operate without an internal cooling fan. MikroTik specifies maximum power consumption of approximately 10W.
The fanless design makes the router suitable for desktop installations, small network cabinets and environments where minimizing mechanical noise is useful.
Suitable for Home and Small Business Networks
The hEX RB750Gr3 can be used as a central wired router for homes, small businesses, branch offices and other compact network environments.
Typical applications include:
- Home and SOHO routing
- Small business networks
- Branch-office routers
- Dedicated firewall and NAT gateway
- VLAN-based network segmentation
- Internet gateway for separate Wi-Fi access points
- VPN gateway applications
- Network lab and testing environments
- Managed wired Ethernet networks
Suitable for Separate Wi-Fi Access Point Deployments
Because the MikroTik hEX RB750Gr3 does not have built-in Wi-Fi, it can be paired with dedicated wireless access points. This can be useful in networks where the router and wireless coverage need to be designed independently.
For example, the hEX can handle routing, firewall, DHCP and VLAN functions while separate access points provide wireless coverage in different rooms, floors or areas.

MikroTik hEX RB750Gr3 for VPN and Firewall
The RouterOS platform makes the hEX RB750Gr3 suitable for networks that require more than basic Internet sharing. Firewall rules, NAT, routing policies and supported VPN technologies can be configured directly on the router.
VPN performance varies significantly depending on the VPN protocol, encryption settings, packet size, number of connections and other enabled RouterOS features. Therefore, published hardware specifications should not be interpreted as a guaranteed VPN throughput figure.
MikroTik hEX RB750Gr3 for VLAN Networks
The five Gigabit Ethernet interfaces can be configured using RouterOS bridge and VLAN functionality to create segmented networks. This can be useful for separating office devices, guest networks, IP phones, CCTV equipment and management traffic.
The exact VLAN architecture depends on the connected switches, access points and other network equipment.
hEX RB750Gr3 Without Wi-Fi
The MikroTik hEX RB750Gr3 does not have built-in wireless. This is an important distinction when comparing it with MikroTik wireless routers such as the hAP series.
If wireless connectivity is required, a separate MikroTik or third-party access point can be connected to one of the Gigabit Ethernet ports.
