Cudy LT12 4G LTE 600 Mbps Wi-Fi 5 AC1200 Cat. 12 Router
The Cudy LT12 router allows LTE FDD data download speeds of up to 600 Mbps thanks to 4 MIMO antennas. This translates into lightning-fast website loading, comfortable online video watching, or listening to music via streaming services. Files download in the blink of an eye. It is therefore an excellent device not only for home use, but also for the needs of a medium-sized company. The device allows you to connect 3 additional devices using a standard Gigabit LAN port and a modem or another device via the LAN / WAN port. This functionality is perfect if you often work in the field and need to share mobile internet with several devices at the same time.
Important features of the WiFi 5 Cat12 router
- External SMA antenna connector- connecting the router to external GSM antennas makes it possible to obtain a stronger and more stable signal
- 4G Backup- after selecting WAN and using fixed-line internet, you can set a 3G/4G connection as a backup link
- Two SIM slots- ensure connection stability. The Cudy router can automatically switch between individual cards when, for example, one of the networks is not working properly
- DNS over TLS- The router supports DNS encryption via CloudFlare, NextDNS or Google. It protects your privacy, prevents eavesdropping and manipulation of DNS data using man-in-the-middle
- 4G band lock- the WiFi5 router allows you to lock the operating frequency on one or several bands in order to maintain stable operation.
High 4G LTE speed with reliable Wi-Fi
The LT12 uses 4G LTE FDD technology to achieve download speeds of up to 600 Mbps and upload speeds of up to 150 Mbps. In the case of 4G LTE TDD, it is max. 430 Mbps (download) and 90.6 Mbps (upload). It also provides a Wi-Fi network with a maximum speed of 300 Mbps on the 2.4 GHz band and 867 Mbps on the 5 GHz band for gaming, streaming, and more.
Designed for maximum coverage
With two tall 5 dBi external 4G LTE antennas, you ensure efficient and stable connections to every device, creating a wide-coverage Wi-Fi network for your home.
Dual SIM Plug and Play
Simply insert a SIM card into the built-in slot, power it on, and start browsing. If it has a PIN code, the device will ask for it automatically. Then the auto-configuration process will start and Cudy will set the appropriate access points (APN) itself and get ready to work. This model has two SIM card slots.
WAN connection backup
Thanks to the fully functional LAN / WAN port, you can use various types of backup connections, including cable, fiber optic, and DSL modems.

OpenWRT
OpenWrt was designed by networking professionals and the community who care about their network performance. Because OpenWrt is a true Linux-based system, you have full control over all router functions.
