## Summary description

Cudy LT400 is a desktop single‑band router operating on 2.4 GHz with Wi‑Fi 4 (802.11n) and up to 300 Mbps throughput. It supports LTE (4G, Cat 4) via NanoSIM and 3G/4G USB modems, features 3 Ethernet LAN ports and 1 WAN RJ‑45, external detachable antennas, QoS, NAT, DDNS, guest network and parental controls. Powered by included AC adapter, it offers web management, LED indicators, reset button and compact dimensions for home or small office use.

## Long description

The LT400 shares a 4G LTE connection wherever you need it. It supports 4G LTE FDD and TDD bands and 3G networks, offers Wi‑Fi on the 2.4 GHz band with up to 300 Mbps, and provides flexible operation modes for home, office or temporary setups. The router includes high‑gain antennas for improved signal sensitivity and supports DDNS and VPN for remote access and secure tunneling.
Advantages
Support for both FDD and TDD LTE ensures compatibility with many ISPs and mobile operators worldwide. Built‑in VPN enables a secure private tunnel for remote offices and teleworkers. Compatibility with more than 15 DDNS providers simplifies remote management when the public IP address changes. High‑gain antennas increase reception range and indoor penetration, and multiple operation modes allow the LT400 to act as a primary router, a WAN‑backed gateway or a simple 4G backup.

 4G LTE TDD: B38 / B40 (2600 / 2300 MHz)
 3G: DC‑HSPA+ / HSPA+ / HSPA / UMTS B1 / B8 (2100 / 900 MHz)

 High‑gain external antennas
 Operation modes: LAN (4G router), WAN + 4G (primary WAN with 4G backup)
How to use
Insert an active SIM card into the LT400 and power on the device. Access the web administration page to configure the mobile network settings or select automatic detection. Set up Wi‑Fi SSID and password on the 2.4 GHz band and configure VPN or DDNS if remote access or secure connections are required. For office deployment, choose WAN + 4G mode to provide Internet primarily via wired ports while keeping 4G as backup; for simple home or vacation use, operate in LAN mode to share the mobile data connection over Wi‑Fi and Ethernet.
Recommendations
Place the LT400 near a window or higher position for better cellular reception, and ensure the SIM plan supports the required data speeds. Use the VPN and DDNS features when remote secure access to the local network or router administration is necessary.
