Dimensions189 x 156 x 30 mm
Weight280 g

If you have limited space available for your router, such as in a small apartment or office, the dimensions can determine whether it can fit in the designated area or not. It's important to consider the physical size of the router, including its height, width, and depth, to ensure it can be accommodated in your space. The weight of a router can be a consideration in certain situations, but it is generally not as crucial as other factors such as performance, features, and compatibility.


ChipsetInfineon AMAZON-S
Flash2 MB
Power supply15 V / 0.8 A

The Infineon AMAZON-S CPU, combined with other factors such as RAM capacity and firmware optimization, determines the overall performance and responsiveness of the router. The SMC7904WBRA-N comes with 32 MB of RAM. The amount of RAM in a router can impact its performance and capacity to handle concurrent operations and traffic. Higher RAM capacity allows for better multitasking, larger routing tables, and improved overall performance.

The 2 MB flash memory in the router serves as the storage medium for the router's firmware. It is a non-volatile memory that retains its data even when power is removed from the device. The SMC often releases firmware updates to enhance the router's functionality, improve security, fix bugs, and add new features. Firmware updates can provide performance improvements, compatibility with new devices or protocols, and address vulnerabilities. The SMC provides the appropriate power supply (15 V / 0.8 A) that matches the voltage requirements of the router. The power supply unit is designed to deliver the correct voltage to the router, ensuring its proper operation.


LAN ports4 x 10/100 Mbps
WAN ports1 x ADSL
Mobile networkno
VPN supportno

Like many modern routers, the SMC7904WBRA-N supports many network standards too. The majority of networking equipment, including routers, switches, and other network devices, is designed to support IPv4. The SMC7904WBRA-N has 4 x 10/100 Mbps LAN and 1 x ADSL WAN ports. The LAN ports of SMC7904WBRA-N router are numbered and are used to establish wired connections between the router and devices such as computers, gaming consoles, smart TVs, network-attached storage (NAS) devices, and other network-enabled devices.

The WAN port on a router stands for "Wide Area Network" port. It is used to connect the router to the external network, typically provided by an internet service provider (ISP). If you have a high-speed internet plan with speeds exceeding 100 Mbps, you may experience a bottleneck in wired connections due to the limitation of the Fast Ethernet ports on the SMC7904WBRA-N router.

This router has 2 x 3.5 dBi antennas. Many modern routers feature multiple antennas and use Multiple-Input Multiple-Output (MIMO) technology. This technology enables simultaneous transmission and reception of multiple data streams, increasing overall throughput and improving the Wi-Fi performance. The SMC7904WBRA-N is compatible with 2.4 GHz Wi-Fi. Many IoT (Internet of Things) devices, smart home devices, and older Wi-Fi-enabled devices primarily operate on the 2.4 GHz band.

The SMC7904WBRA-N is a Wi-Fi 4 (802.11n) router. N routers may have a more limited range compared to newer Wi-Fi standards, making them less suitable for larger homes or offices where Wi-Fi coverage is a concern. The N300 refers to the maximum combined data transfer rate supported by the router across all Wi-Fi bands. The SMC7904WBRA-N is capable of a maximum throughput speed of 300 Mbps. The real-world speed of a SMC7904WBRA-N router is typically lower than its theoretical maximum speed.

The maximum TX power of SMC7904WBRA-N router is 17.5 dBm. Adjusting the TX power of a router can be useful in situations where you want to optimize the Wi-Fi signal strength and coverage. The SMC7904WBRA-N router offers several security protocols: WEP, WPA, WPA2. The WEP (Wired Equivalent Privacy) was the first security protocol for Wi-Fi networks but is now considered weak and easily compromised. It uses a static encryption key and has known vulnerabilities, so it is no longer recommended for securing Wi-Fi networks. The WPA2 (Wi-Fi Protected Access 2) was introduced as an improvement over WEP and provides stronger security. If WPA3 is not available, WPA2-Personal with AES encryption is still considered secure.
