wired router Mikrotik RB750GR3

The wired router Mikrotik RB750GR3 (hEX) is a compact five-port Gigabit Ethernet router designed for environments where wired connectivity is preferred or required. It is powered by a MIPS64 dual-core processor running at 880 MHz and equipped with 256 MB RAM and 0.16 GB internal storage. The device includes five Gigabit RJ-45 LAN ports and a full-size USB port, and offers IPsec hardware encryption support. Its small footprint (113 × 89 × 28 mm) and DC power input make it suitable for home offices, small businesses, and network edge deployments that need reliable wired performance.

Advantages

The RB750GR3 provides Gigabit Ethernet throughput across five LAN ports and a full-size USB port for storage or peripheral connectivity. Its updated hardware revision brings a more powerful dual-core 880 MHz CPU and increased RAM for improved routing performance and support of advanced RouterOS features. Built-in IPsec hardware encryption accelerates secure VPN traffic, and a microSD slot allows faster read/write for external database or logging storage. The router’s compact, low-profile design and two-tone white and turquoise finish simplify installation in constrained spaces.

Suitable for

• Small office or home office wired networks requiring Gigabit LAN
• Edge router for small business internet connectivity and VPN termination
• Network setups that need a compact wired router with USB storage options
• Environments where a non‑wireless, dedicated wired connection is preferred

How to use

Connect the Mikrotik RB750GR3 to your network by linking your internet uplink to one of the router’s Gigabit ports and attaching client devices to the remaining LAN ports. Plug in the DC power adapter and access the device using the RouterOS web interface, Winbox application, or SSH to perform initial configuration. Use the USB or microSD slot to attach external storage for logs or databases if required. Enable and configure IPsec in RouterOS for secure VPN tunnels; the hardware encryption will accelerate VPN throughput without additional steps beyond standard RouterOS configuration.

Usage recommendations

Place the router in a ventilated, dry location away from direct heat sources. Keep firmware (RouterOS) updated to ensure security and performance improvements, and configure appropriate firewall and VPN settings for secure network operation. For best performance on heavy VPN or throughput loads use high-quality CAT5e/6 cabling and a stable DC power supply that meets the device’s requirements.
