Network Card MikroTik R52HND Internal WLAN

The MikroTik R52HnD Internal WLAN network card is an updated miniPCI wireless adapter compatible with Wi‑Fi 4 (802.11n). It supports both 2.4 GHz and 5 GHz bands, offers increased transmit power compared to the previous R52Hn model, and includes improved ESD protection up to ±15 kV. The card uses a Mini PCI host interface and comes in a green housing suitable for integration into compatible routers and embedded systems.

Advantages

The R52HnD provides dual‑band operation (2.4/5 GHz) and higher output power for improved range and throughput in networks that use 802.11n. Enhanced electrostatic discharge (ESD) protection reduces the risk of hardware damage during installation and handling. The Mini PCI form factor ensures compatibility with devices that accept internal WLAN cards.

Suitable for

• Upgrading internal WLAN capability in routers and gateway devices
• Embedded systems and miniPCs with Mini PCI slots
• Small office or home networks requiring 802.11n connectivity on 2.4 GHz and 5 GHz

Key specifications

• Standard: IEEE 802.11n (Wi‑Fi 4)
• Bands: 2.4 GHz and 5 GHz
• Interface: Mini PCI (host interface)
• ESD protection: ±15 kV
• Color: Green

How to use

Power down the host device and insert the R52HnD into an available Mini PCI slot, securing it according to the host’s instructions. Reconnect power and ensure the device firmware or operating system recognizes the card. Configure wireless settings (SSID, channel, security) via the router or system management interface to enable network access on the chosen band(s).

Recommendations

Install the card in a properly grounded environment and handle it by the edges to reduce static discharge risk. Use compatible drivers or firmware updates provided by the device vendor to ensure stable operation. For best wireless performance, place antennas and the host device to minimize obstructions and interference.
