ZyXEL NBG4115 (NBG4115) specifications

Body

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. If you purchase a router online or have it shipped, the weight may affect the overall cost. Heavier routers can result in higher shipping charges, especially for international deliveries.

System

The Ralink RT3050F @ 320 MHz CPU, combined with other factors such as RAM capacity and firmware optimization, determines the overall performance and responsiveness of the router. The NBG4115 has 32 MB of RAM. Some advanced router features and software functionalities require a certain amount of RAM to operate properly. For example, routers with more RAM can support advanced security features, VPN services, or QoS (Quality of Service) prioritization more effectively.

The NBG4115 has 4 MB of flash memory. A larger flash memory allows for more storage space to accommodate future firmware upgrades. The process of upgrading the firmware on routers has become relatively simple and user-friendly over the years. The ZyXEL provides easy-to-use interfaces and instructions to guide users through the firmware upgrade process. The ZyXEL provides the appropriate power supply (12 V / 1.25 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.

Network

The NBG4115 router offers built-in security features to protect your network and connected devices. The majority of networking equipment, including routers, switches, and other network devices, is designed to support IPv4. The NBG4115 has 2 x 10/100 Mbps LAN and 1 x 10/100 Mbps WAN ports. The LAN ports of NBG4115 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.

WAN ports often require specific configuration settings based on the type of internet connection provided by your 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 NBG4115 router. By connecting the 3G/4G USB dongle to the NBG4115 router, you can share the internet connection with multiple devices on your local network. This allows multiple devices, such as computers, smartphones, or smart home devices, to access the internet simultaneously.

Wireless

This router has 1 x 2 dBi, RP-SMA 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. This router is 2.4 GHz capable. The 2.4GHz band refers to the portion of the radio spectrum between 2.400 and 2.4835 gigahertz. This frequency range is unlicensed and globally available for various wireless applications, including Wi-Fi.

The NBG4115 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 N150 refers to the maximum combined data transfer rate supported by the router across all Wi-Fi bands. The NBG4115 is capable of a maximum throughput speed of 150 Mbps. The real-world speed of a NBG4115 router is typically lower than its theoretical maximum speed.

The maximum TX power of NBG4115 router is 27 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 NBG4115 router offers several security protocols: WEP, WPA, WPA2, WPS. 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. The NBG4115 router offers WPS. The WPS (Wi-Fi Protected Setup) provides a simplified and convenient method for connecting devices to a Wi-Fi network. Instead of manually entering the Wi-Fi network name (SSID) and password, users can use the WPS feature to establish a connection with the push of a button or by entering a PIN.

Connectivity

USB ports can offer additional functionality depending on the router's capabilities. The USB 2 port has a maximum theoretical data transfer rate of 480 megabits per second (Mbps), which is equivalent to 60 megabytes per second (MB/s).

Administration

The ZyXEL router setup panel is accessed through a web browser. Connect your computer to the NBG4115 router via Wi-Fi or Ethernet cable. In the address bar of the web browser, type in the 192.168.1.1 IP address. If you are unable to log in to the setup panel of your ZyXEL router, performing a reset can be a helpful troubleshooting step. It is highly recommended to change the default password of your NBG4115 router after the initial setup. If you forget the new password in the future, you may need to perform a factory reset on the router to revert to the default settings.
