This port is used to connect the router to your internet service provider’s network. It can support high-speed internet connections and ensures that your router can handle the fastest internet speeds available.
• 4G Failover: The 4G failover feature is important for ensuring continuous internet connectivity. If your primary internet connection (such as the WAN port) experiences issues or goes down, the router can automatically switch to the 4G connection, providing a backup internet source to keep your network online.
• LTE Band Support: The router supports multiple LTE bands, including Bands 1, 3, 5, 7, 8, 20, 38, 40, and 41. These bands represent various frequency ranges used by mobile network providers. Support for multiple bands ensures compatibility with a wide range of networks, which is particularly useful if you travel or use different SIM cards from various providers.
• HSPA Band Support: In addition to LTE, the router also supports HSPA (High-Speed Packet Access) Bands 1 and 8. HSPA is an older 3G technology that provides relatively high-speed data transmission. This support can be useful in areas where 4G coverage is limited or unavailable.
• EU Plug: The router comes with an EU plug, which is compatible with European power outlets. Ensure that the plug matches the power outlets in your region or use an appropriate adapter or power cord if needed.

• Latest ADSL2/2+ Standards: This device supports the ADSL2 and ADSL2+ standards, which are common technologies used for internet connections over traditional telephone lines. These standards provide internet transmission speeds of up to 24 Mbps downstream (download) and 1 Mbps upstream (upload). This means it’s capable of delivering relatively fast internet access over DSL connections.
• Compatibility with Older 802.11g/b Devices: The device is compatible with older 802.11g and 802.11b wireless devices. This suggests that it likely includes Wi-Fi functionality, allowing you to connect wireless devices to your network. 802.11g and 802.11b are older Wi-Fi standards that offer lower data transfer rates compared to newer standards like 802.11n or 802.11ac.
• Switchable WAN/LAN Port: This feature indicates that one of the Ethernet ports on the device can be configured to function either as a Wide Area Network (WAN) port or a Local Area Network (LAN) port. In WAN mode, it’s used to connect to your DSL line, while in LAN mode, it can be used to connect wired devices to your local network.
• USB 2.0 Port for 3G USB Modem: The device includes a USB 2.0 port that can be used to connect a 3G USB modem. This feature allows you to use a 3G cellular connection as a backup internet source if your DSL connection goes down. It’s a useful redundancy option.

• Wireless Standard: Wireless AC 1200, which includes support for 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac Wi-Fi standards.
• Dual Band: It operates on both the 2.4 GHz and 5 GHz frequency bands, allowing for better performance and reduced interference.
• Ports: It has 4 Gigabit Ethernet ports, which provide high-speed wired connections.
• Gigabit WAN: The router includes a Gigabit WAN (Wide Area Network) port for connecting to high-speed internet services.
