ZyXEL NBG2105 (NBG2105) specifications

Body

The dimensions and design of a router can impact its cooling capabilities. Routers with larger dimensions may have more space for internal cooling mechanisms, such as larger fans or heat sinks, which can help dissipate heat more effectively. The weight of router is not typically a critical factor for most home or office setups.

System

The ZyXEL NBG2105 router is equipped with Realtek RTL8196EU @ 400 MHz processor. The router's memory (32 MB) cannot be expanded. When choosing a router, it is important to consider both the flash memory and RAM specifications. The NBG2105 has 4 MB of flash. A larger flash memory allows for more space to store configuration backups. It enables you to save multiple versions of your router's configuration settings, which can be useful for restoring previous configurations or reverting changes if needed.

Within the NBG2105 router's interface, look for a section related to firmware or system settings. The exact location and wording may vary depending on the router's make and model. The ZyXEL NBG2105 router comes with 5 V / 1 A PSU. This unit is responsible for providing electrical power to the router, and if it becomes faulty, it can be replaced with a new, compatible one.

Network

The NBG2105 router supports multiple networking standards to ensure compatibility with various devices and systems. The IPv4 is the fourth iteration of the Internet Protocol (IP) and is the most widely used version of IP on the internet today. The ZyXEL NBG2105 has no LAN and 1 x 10/100 Mbps WAN ports. LAN or Ethernet ports (RJ-45) are used to connect devices to the local area network (LAN). WAN ports are the entry point to your local network, making them a potential target for unauthorized access or attacks. It's important to secure your WAN connection by using strong passwords, enabling encryption protocols, and keeping the router's firmware up to date to mitigate security risks. The WAN port on the NBG2105 router is a Fast Ethernet port, not a Gigabit Ethernet. The Fast Ethernet ports are capable of supporting speeds up to 100 Mbps, which is still suitable for most internet connections.

Wireless

This router has 1 x 2 dBi, internal antennas. Antennas play a significant role in Wi-Fi performance and coverage. They are essential components of wireless routers that transmit and receive radio signals to establish wireless connections with devices. The NBG2105 is compatible with 2.4 GHz Wi-Fi networks. 2.4 GHz is the most widely used frequency and in some cases may be overcrowded. The NBG2105 is a Wi-Fi 4 (802.11n) router. Wi-Fi 4 improved the range and coverage compared to previous Wi-Fi standards. The use of MIMO technology and other enhancements help to mitigate signal degradation and provide better coverage in larger homes or office environments. This allows devices to maintain a stable connection even when located farther away from the Wi-Fi router.

The N150 is a performance indicator that represents the router's theoretical maximum speed. The theoretical maximum speed (150 Mbps) represents the highest data transfer rate that the router is capable of achieving under ideal conditions. The TX power (16 dBm) of a router refers to the transmission power or signal strength at which the router broadcasts its Wi-Fi signal. It determines the range and coverage area of the wireless network.

The NBG2105 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 NBG2105 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

The NBG2105 router doesn't have file-server or print-server functionality.

Administration

The default IP addresses of the ZyXEL NBG2105 device is 192.168.1.1. These address allows you to access the router's console login page. Regularly changing the password is a good security practice to protect your network and devices from unauthorized access. It is also recommended to use strong, unique passwords for other devices and online accounts connected to your network for enhanced security. By changing the default password, you improve the security of your router and reduce the risk of unauthorized individuals gaining control over your network. It helps prevent unauthorized access to your router's settings, network configurations, and sensitive information.
