Wireless router RUIJIE RG-EG105G-V3 Dual Band Wi‑Fi 5, 2 cores, 128 MB RAM, 32 MB flash, 4 LAN + 2 WAN Gigabit ports, black

RUIJIE RG-EG105G-V3 is a compact dual-band Wi‑Fi 5 router intended for small offices and homes. It is housed in a black case, supports up to 100 users and operates in ambient temperatures from 0 to 40 °C. The router provides Gigabit Ethernet connectivity via four LAN ports and two WAN ports and is CE and RoHS certified.

Advantages

The device integrates a dual-core processor with 128 MB of RAM and 32 MB of flash memory to handle typical small-office and home networking tasks. Gigabit Ethernet ports (10/100/1000Base-T) on both LAN and WAN interfaces enable high-speed wired connections. Its compact dimensions and modest 12 W typical power consumption make it suitable for constrained spaces and energy-aware deployments.

Suitable for

• Small office networks
• Home broadband and Wi‑Fi access
• Environments requiring multiple wired connections (up to 4 LAN and 2 WAN)

How to use

Place the router in a ventilated location within the specified operating temperature range. Connect the Internet source to one of the WAN RJ‑45 ports and wired devices to the LAN ports; configure wireless and network settings via the router’s management interface according to the vendor documentation. Ensure firmware is kept up to date and follow standard network security practices, such as setting a strong administrator password and configuring WPA2/WPA3 for Wi‑Fi.

Recommendations

For stable wireless coverage, position the router centrally in the coverage area and avoid obstructions. Use the Gigabit LAN and WAN ports for bandwidth‑sensitive wired devices. Monitor connected users and traffic to maintain expected performance when approaching the 100-user capacity.
