The MikroTik RB951Ui-2HnD is one of the most reliable and popular desktop wireless routers in the MikroTik product lineup, engineered specifically for small office, home office (SOHO), and managed ISP customer installations. Combining high-power 2.4 GHz wireless connectivity with versatile PoE flexibility, it offers enterprise-class network management in a compact desktop enclosure.
Driven by an Atheros AR9344 600 MHz CPU paired with 128 MB RAM and 128 MB NAND storage, the router easily handles complex packet processing, hotspot gateways, custom firewall rules, and dynamic queue management. Its integrated dual-chain 2.4 GHz wireless radio supports 802.11b/g/n standards with high output power (up to 1000 mW), providing superior wall penetration and extended indoor coverage.
The RB951Ui-2HnD features 5x 10/100 Fast Ethernet ports: Port 1 accepts Passive PoE input, while Port 5 provides Passive PoE output to power downstream devices (such as IP cameras or secondary access points) with the same voltage applied to the unit. Additionally, a USB 2.0 Type-A port allows for external 3G/4G cellular modem attachments or storage expansion. Operating on MikroTik RouterOS Level 4, it grants administrators unrestricted access to routing protocols, VPN management, bandwidth shaping, and network security policies.
