MikroTik RB5009UG+S+IN (Wired Router/No WiFi Radio/RouterOS/2.5G+10G SFP+ Ports) Review
MikroTik RB5009UG+S+IN wired-only router with RouterOS v7, full 802.1Q VLAN tagging, 2.5G Ethernet, a 10G SFP+ uplink port, quad-core ARM64 CPU, and enterprise-grade routing features for home lab and small business networks.
The RB5009 has become a favorite among home-lab and small-business networking enthusiasts because it packs a 10G SFP+ port and 2.5G Ethernet into a compact fanless box running MikroTik's genuinely powerful RouterOS v7 on a quad-core 1.4GHz ARM64 CPU with 1GB of RAM. It supports full 802.1Q VLAN tagging with hardware offload, making it a realistic core router for a segmented home lab (management, IoT, guest, and server VLANs on one box). It has no wireless radio at all, so it's meant to sit alongside separate access points rather than replace them — but as a routing, firewall, and VLAN trunking core, it punches well above its price.
Overview
A fanless, wired-only router built around RouterOS v7, with a 10G SFP+ uplink, a 2.5G port, and seven Gigabit ports, driven by a quad-core 1.4GHz ARM64 CPU with 1GB RAM. Aimed at enthusiasts and small businesses that want serious routing power without enterprise pricing.
VLANs and Home Lab Suitability
RouterOS v7 supports full 802.1Q VLAN tagging and trunking across all ports, with hardware offload on the built-in switch chip keeping VLAN-tagged traffic at line rate rather than burdening the CPU. That makes the RB5009 realistic as a home lab's core router: trunk a VLAN-aware managed switch or access point into one port, split traffic into management/IoT/guest/server VLANs, and route or firewall between them entirely in RouterOS. The 1GB of RAM and quad-core CPU comfortably handle VLAN interfaces, NAT, and a stateful firewall simultaneously, and PoE-in on Ether1 with passive PoE passthrough on the remaining ports simplifies powering a VLAN-tagged access point downstream.
Comparison to Alternatives
Against the MikroTik hEX S, the RB5009 offers vastly more throughput headroom (10G SFP+ and 2.5G vs no multi-gig ports at all) and a modern quad-core 1.4GHz CPU versus the hEX S's dual-core 880MHz chip, at roughly triple the price. Compared to the Ubiquiti UniFi Dream Machine Pro Max ($379), the RB5009 costs under half as much and offers more granular RouterOS-level control over VLANs, firewall rules, and routing protocols, though it lacks UniFi's polished web UI and built-in NVR/controller features. Against the TP-Link Omada ER8411 ($130, 2.5G router), the RB5009 adds a full 10G SFP+ uplink and RouterOS's far deeper CLI-level configurability at a similar price point. For buyers considering a repurposed PC running pfSense or OPNsense (e.g., a Protectli Vault), the RB5009 draws far less power (under 15W vs 20-40W+) and needs no fan, at the cost of RouterOS's steeper learning curve versus pfSense's more mainstream web GUI. Buyers wanting integrated WiFi should pair it with a separate access point like the Ubiquiti UniFi 6 Lite or MikroTik's own cAP ax, since the RB5009 has no wireless radio of its own.
