MikroTik RB951Ui-2HnD — Enterprise-Grade Network Power in a Compact SOHO Package

2.4GHz Wireless Access Point | 5-Port Fast Ethernet | PoE Output | RouterOS Level 4 | USB 3G/4G Ready

Your network is the backbone of everything — every file transfer, every video call, every transaction, every connected device depends on it. The MikroTik RB951Ui-2HnD RouterBOARD is built for the IT professional, network administrator, small business owner, and savvy home user who refuses to accept average. This isn’t just a router. It’s a fully configurable, enterprise-class networking platform packed into a compact, affordable SOHO device that will outlast, outperform, and out-configure anything else in its price range.

🖥️ What Is the MikroTik RB951Ui-2HnD and Who Needs It?

The MikroTik RouterBOARD RB951Ui-2HnD is a small five-port Ethernet Wireless-N Access Point in a plastic case — an attractive, tiny SOHO unit that is perfect for extending your wired and wireless home or office network.

But don’t let the word “small” mislead you. Under the hood, this device is a powerhouse of routing intelligence. Unlike consumer-grade routers that lock you into a limited GUI with no real control, the RB951Ui-2HnD runs MikroTik RouterOS — the same operating system used by ISPs, data centres, and enterprise networks worldwide.

This device is the ideal choice for:

• IT administrators managing small-to-medium business networks
• Wireless ISPs (WISPs) deploying affordable customer premises equipment
• Network engineers who need granular traffic control and advanced routing
• Home power users who want firewall, VPN, and hotspot capabilities without enterprise pricing
• Retail and hospitality businesses running captive portal hotspot networks
• Remote offices and branch networks requiring secure, reliable connectivity

⚙️ Powered by a 600MHz Atheros CPU — Processing That Means Business

The Brains Behind the Network

At the core of the RB951Ui-2HnD is a Qualcomm Atheros AR9344 processor running at 600MHz, paired with 128MB of DDR2 RAM. As the hardware basis, a performant Qualcomm Atheros AR9344 processor operating at a clock frequency of 600MHz and 128MB of RAM is used — capable of powering smooth, reliable routing, firewall processing, and wireless operations simultaneously.

This processing headroom means the device can handle multiple demanding tasks concurrently without dropping packets or degrading wireless performance:

• Stateful firewall rules processing every packet at line speed
• Active VPN tunnels (IPsec, OpenVPN, PPTP, L2TP) without causing significant throughput degradation
• Bandwidth management and QoS shaping traffic in real time
• Hotspot gateway with simultaneous user authentication and session tracking
• VLAN routing across multiple logical network segments

This is the processing muscle that sets MikroTik apart from every consumer router in its class.

📡 High-Power 2.4GHz Wireless — 1000mW of Signal Strength

Coverage That Reaches Where Other Routers Can’t

The wireless module in the RB951Ui-2HnD is not a standard output radio — it’s a high-power 1000mW (30dBm) 2.4GHz 802.11b/g/n access point with dual built-in antennas. It has a high-power 2.4GHz 1000mW 802.11b/g/n wireless AP with antennas built in, delivering stable and long-range wireless coverage for small office and home environments.

Key wireless capabilities include:

• 802.11b/g/n standards — backward compatible with virtually all Wi-Fi devices
• 2×2 MIMO technology — up to 300 Mbps maximum wireless data rate
• 2.5 dBi antenna gain — extended range and signal penetration through walls and obstacles
• Multiple virtual SSIDs — broadcast separate networks for staff, guests, and management simultaneously
• WPA2/WPA3 security — enterprise-grade wireless encryption
• Wireless bridging and AP mode — flexibility for complex deployment topologies

The MikroTik 951Ui-2HnD supports MIMO multi-channel transmission technology and is capable of providing data exchange rates up to 300 Mbps — ideal for high-demand wireless environments.

🔌 5x Fast Ethernet Ports + PoE Output — Wired Flexibility Built In

Connect More. Power More. Control More.

The RB951Ui-2HnD ships with five 10/100 Fast Ethernet ports, giving you flexible wired connectivity for desktops, IP phones, managed switches, NAS devices, and more — all from a single compact unit.

PoE Output on Port 5 — Power Your Devices Over the Cable

The PoE output function on port 5 can power other PoE-capable devices with the same voltage as applied to the unit, with a maximum load of 500mA. This means you can power a second MikroTik device, a PoE IP camera, or a wireless access point directly from the RB951Ui-2HnD — no separate power supply required.

The Ether5 port outputs approximately 2V below input voltage and supports up to 0.58A — so a provided 24V PSU will deliver a 22V/0.58A output to the Ether5 PoE port. The port also has an auto-detection feature, so you can connect laptops and other non-PoE devices without risk of damage.

PoE Input on Port 1

The device also supports passive PoE input on Ether1 (8–30V DC), allowing the RB951Ui-2HnD itself to be powered over the Ethernet cable — ideal for ceiling or wall deployments where a mains power outlet is not conveniently located.

🔒 RouterOS Level 4 — Enterprise Networking Features, Included for Free

The Operating System That Separates MikroTik from Everyone Else

Running MikroTik’s powerful RouterOS (licence level 4), the RB951Ui-2HnD unlocks stateful firewall, NAT, VPN (IPsec, OpenVPN), hotspot manager, VLAN support, QoS, bandwidth shaping, and detailed monitoring tools — configurable via WinBox, WebFig, or CLI for complete network control.

RouterOS Level 4 is pre-installed, pre-licensed, and ready to use out of the box. No subscription fees. No hidden costs. No feature paywalls. Here’s what you get as standard:

🔥 Advanced Firewall & Security

Full stateful packet inspection firewall with per-IP, per-MAC, and per-interface rule chaining. Protect your network from external threats, block unwanted traffic, and enforce strict access policies.

🌐 VPN Server & Client

RouterOS turns the RB951Ui-2HnD into a full VPN server with support for IPsec, OpenVPN, PPTP, and L2TP — enabling remote employees to securely connect to your network from anywhere in the world.

🏨 Hotspot Gateway with Captive Portal

Deploy a branded hotspot login page for guests, customers, or tenants. Set per-user data limits, time quotas, and authentication profiles. The secure access features include hotspot authentication, user profiles, and RADIUS integration for controlled, auditable network access.

📊 QoS and Bandwidth Management

RouterOS allows you to limit speed by IP and MAC addresses, create incoming connections from several providers, organise backup communication channels, and fine-tune the firewall, proxy, or FTP server.

🏷️ VLAN Segmentation

Separate your network into logical segments — isolate staff, guests, IoT devices, and servers on individual VLANs for enhanced security and performance.

🤖 Scripting & Automation

Custom scripting enables automation of tasks using RouterOS scripts and the built-in scheduler — streamlining repetitive configuration tasks and enabling intelligent, event-driven network responses.

📶 USB 2.0 Port — 3G/4G/LTE Failover Connectivity

Never Lose Connectivity Again

Thanks to the presence of a USB port, the router is able to work with 3G/4G modems — providing cellular backup when your primary wired internet connection goes down.

This is a critical feature for:

• Business continuity — keep operations running during ISP outages
• Remote site deployments where no fixed-line internet is available
• Primary 4G internet for locations without fibre or DSL coverage
• Dual-WAN load balancing — use wired and cellular simultaneously

Simply plug in any compatible USB 3G/4G modem and configure failover in RouterOS — your network stays online even when your primary ISP doesn’t.

💡 Lifetime Free Software Updates — A Network Investment That Grows With You

One of the most compelling value propositions of the RB951Ui-2HnD is MikroTik’s unmatched software support commitment. The device includes free software updates for the life of the product or a minimum of 5 years starting from the date of purchase — with no separate purchase necessary and the device ready to use right out of the box.

This means:

• New RouterOS features are delivered to your existing hardware automatically
• Security patches are applied without purchasing new hardware
• Your device’s capabilities continue to expand over time — not diminish
