The Cudy LT18 4G LTE Cat 18 WiFi 6 Router is a powerhouse for those seeking fast and reliable internet connectivity. With its Qualcomm chipset, 4x4 MIMO technology, and support for dual-band WiFi 6, this router delivers speeds of up to 1201 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band. Whether you're streaming HD videos, gaming online, or sharing large files across multiple devices, the LT18 ensures a seamless experience.

One standout feature is its dual SIM capability with WAN failover, ensuring you stay connected even if one network fails. The detachable antennas allow for flexibility in installation, and the option to use external antennas enhances signal quality. Additionally, the router supports multiple VPN clients like OpenVPN and WireGuard, making it a secure choice for remote work or private browsing.

Users have praised its performance in challenging environments. For instance, one reviewer noted that despite living near a congested amusement park tower, the LT18's band-locking feature allowed them to connect to less crowded bands, achieving speeds over 100 Mbps on LTE compared to a congested 20 Mbps on nearby towers.

However, there are some limitations. The router only supports 2x2 WiFi, which may limit speeds between devices in high-noise environments. Additionally, while carrier aggregation can boost speeds significantly when active, it doesn't always engage consistently.

Overall, the Cudy LT18 is an excellent choice for those needing a robust LTE router with advanced features like VPN support and dual SIM redundancy. Its performance in both stationary and mobile setups (like RVs) makes it a versatile solution for various internet needs.
