description MikroTik RB5009UG+S+ Overview
While primarily running RouterOS, the MikroTik RB5009UG+S+ is a powerhouse of networking hardware that some users explore for its raw capabilities. It features a powerful ARM CPU and 10G SFP+ ports, making it an elite choice for high-bandwidth fiber connections. Although not natively 'OpenWrt' in the same way as others, its hardware architecture is often used as a reference for what high-end OpenWrt builds aim to achieve.
help MikroTik RB5009UG+S+ FAQ
Can the MikroTik RB5009UG+S+ replace a small rack router?
Yes, for many home labs and small offices it can, because it combines seven gigabit Ethernet ports, one 2.5G Ethernet port, and one 10G SFP+ cage. It runs RouterOS v7, which gives access to advanced routing, VLANs, firewalling, WireGuard, and monitoring features.
Is the RB5009UG+S+ a straightforward OpenWrt box?
No, it should be treated as a RouterOS-first MikroTik router, not a plug-and-play OpenWrt single-board computer. Anyone planning to flash OpenWrt should check the current OpenWrt device support notes for the exact RB5009 variant before buying.
Why do fiber users like the RB5009UG+S+?
The 10G SFP+ port makes it attractive for fiber handoffs, DAC links to switches, or lab uplinks. The 2.5G Ethernet port is also useful for faster-than-gigabit WAN or LAN devices without needing an all-10G router.
How does the RB5009UG+S+ differ from MikroTik's hEX or hAP routers?
The RB5009UG+S+ is a higher-performance wired router built around an ARM platform and faster uplink options. Smaller hEX or hAP models are cheaper and simpler, but they do not offer the same 10G SFP+ path.
