|Dimensions||175 x 115 x 23 mm|
If you plan to move or travel frequently and need to take your router with you, the dimensions become important for portability. Smaller and more compact routers are generally easier to transport, while larger routers with external antennas or multiple ports may be bulkier and less convenient to carry. 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.
|Chipset||MediaTek MT7620A @ 580 MHz|
|Power supply||12 V / 1 A|
The MediaTek MT7620A @ 580 MHz CPU provides processing power to handle various tasks and services within the AC750 NBG6515 router. The AC750 NBG6515 has 64 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 AC750 NBG6515 has 8 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 packages the AC750 NBG6515 router with 12 V / 1 A PSU. A good PSU is an essential component of a computer or electronic device that converts electrical power from an outlet into the appropriate voltage and current required to power the internal components of the device.
|LAN ports||4 x 10/100/1000 Mbps|
|WAN ports||1 x 10/100/1000 Mbps|
The AC750 NBG6515 router offers built-in security features to protect your network and connected devices. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The AC750 NBG6515 router also supports IPv6 protocol, allowing you to utilize the latest version of the Internet Protocol. The LAN ports are physical connectors on a AC750 NBG6515 router that allow you to connect devices to your local network using Ethernet cables.
This router has Gigabit Ethernet LAN ports. If you have a high-speed internet plan that offers speeds of 1 Gbps or higher, gigabit Ethernet ports are essential to fully utilize the available bandwidth. WAN ports often require specific configuration settings based on the type of internet connection provided by your ISP. The AC750 NBG6515 router supports Gigabit speed on its WAN port, that can support speeds up to 1000 Mbps. This router ensures that you can fully utilize high-speed internet connections provided by your ISP.
|Antennas||2 x 5 dBi|
|Speed||300 + 433 Mbps|
|Transmit power||20 dBm|
The 2 x 5 dBi, fixed antennas of AC750 NBG6515 influence the quality and stability of the Wi-Fi signal. A properly positioned and well-designed antenna can minimize interference and signal degradation, leading to a more reliable and stable connection. The AC750 NBG6515 supports the 2.4 GHz Wi-Fi. It is one of the most common frequency bands used for Wi-Fi networks. The AC750 NBG6515 supports 5 GHz signals. Most modern devices, such as smartphones, tablets, laptops, and smart TVs, support dual-band Wi-Fi, which means they can connect to both 2.4 GHz and 5 GHz networks. By utilizing the 5 GHz band, you can offload some devices from the crowded 2.4 GHz band, reducing congestion and improving overall network performance.
The AC750 NBG6515 AC Wi-Fi router is backward compatible with older Wi-Fi devices that support 802.11a/b/g/n standards. The AC750 refers to the maximum combined data transfer rate supported by the router across all Wi-Fi bands. The AC750 NBG6515 is capable of a maximum throughput speed of 300 + 433 Mbps. The real-world speed of a AC750 NBG6515 router is typically lower than its theoretical maximum speed.
The TX power of AC750 NBG6515 can be adjusted by the user or set automatically by the router firmware. Higher TX power values indicate stronger signal transmission, which can result in a larger coverage area. The AC750 NBG6515 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. The ZyXEL AC750 NBG6515 router is capable of creating a guest network. Guests connected to the guest network usually have limited access to network settings and configurations. They are typically restricted from accessing devices connected to the primary network, such as printers, network-attached storage (NAS), or other shared resources.
|USB ports||1 x USB 2.0|
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). By connecting a USB printer to the AC750 NBG6515 router, you can make it accessible to all devices on your network. This eliminates the need for individual printer connections and allows multiple devices to use the printer simultaneously. The USB file server functionality of this router allows you to connect external storage devices, such as USB flash drives or hard drives to your network. This enables easy file sharing and access among devices connected to the network.
The default IP address of this router is 192.168.1.1. Explore the router's configuration interface to access more advanced settings such as port forwarding, DHCP settings, parental controls, firewall settings, and QoS (Quality of Service) settings. 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 AC750 NBG6515 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.
