Ruijie RG-EW300R Mesh Wi‑Fi System Single‑band 2.4 GHz Wi‑Fi 4 (802.11n) White 1x External Antenna

Ruijie RG-EW300R is a compact mesh Wi‑Fi system that operates on the single 2.4 GHz band with Wi‑Fi 4 (802.11n) support and up to 300 Mbps WLAN throughput. The unit comes in a white enclosure, features one external antenna and a single Ethernet LAN (RJ-45) port. It is powered by a 100–240 V AC adapter (50/60 Hz) and is intended to provide simple wireless coverage extension for homes and small offices.

Advantages

The RG-EW300R offers straightforward setup and mesh-capable coverage on the 2.4 GHz band, delivering compatibility with legacy Wi‑Fi 4 devices and stable basic wireless performance up to 300 Mbps. Its compact white housing and single external antenna make it easy to place in typical indoor environments, while the onboard Ethernet LAN port allows connection to a wired modem or router.

Suitable for

• Extending Wi‑Fi coverage in apartments or small homes
• Small office areas with modest wireless needs
• Legacy devices that require 2.4 GHz Wi‑Fi 4 connectivity
• Simple mesh expansion where single‑band operation is sufficient

When it may not be suitable

This single‑band (2.4 GHz) device and Wi‑Fi 4 (802.11n) standard are not designed for high‑speed multi‑device environments, modern Wi‑Fi 5/6 clients, or bandwidth‑intensive applications such as 4K streaming and large file transfers. If you need dual‑band operation, higher throughput, or advanced features (MU‑MIMO, OFDMA, WPA3), consider a newer dual‑band or Wi‑Fi 5/6 model.

Key specifications

• Wireless standard: IEEE 802.11n (Wi‑Fi 4), single‑band 2.4 GHz
• Maximum WLAN throughput: up to 300 Mbps
• Antenna: 1 external antenna
• Ethernet: 1 × RJ‑45 Ethernet LAN port
• Power: 100–240 V AC adapter, 50/60 Hz
• Colour: White
• Weight: 0.14 kg

How to use

Connect the RG-EW300R to power via the supplied AC adapter and use the Ethernet LAN port to connect to your modem or upstream router if required. Follow the manufacturer’s setup procedure to join the device to an existing mesh network or to configure it as an access point/ extender on the 2.4 GHz band. Place the unit in a central indoor location for optimal coverage and avoid obstructions or metal objects that can degrade signal strength.

What to consider before purchase

• Only supports single‑band 2.4 GHz (no 5 GHz support)
• Wi‑Fi standard limited to 802.11n (Wi‑Fi 4), maximum 300 Mbps
• Single external antenna and a single Ethernet LAN port
• Intended for basic coverage extension in small spaces, not high‑density deployments

Recommendations

Use the RG-EW300R to improve 2.4 GHz coverage where most devices are legacy or low‑bandwidth clients. Position units evenly across the coverage area, keep firmware updated, and avoid colocating near large metal appliances or cordless phone bases to maintain the best possible signal.
