After weeks of testing the Cudy LT18 in my RV and home, I'm blown away by its performance as a 4G LTE router. The Qualcomm-powered modem consistently delivers speeds over 100Mbps - a massive upgrade from my previous Netgear units that kept disconnecting.
The Good Stuff: The band locking feature is a game-changer! Living near a congested amusement park tower, I forced it to use a less crowded LTE band and saw speeds jump from 20Mbps to 100+. The detachable antennas (I use Peplink Pepwave 42G) make it perfect for mobile setups.
Real-World Use: Mounted to my RV ceiling with external antennas, it handles video calls while driving through rural areas. The dual SIM slots saved me when one carrier had dead zones. Temperature tolerance (up to 110°F+) means it survives hot summer days in the parked RV.
Annoyances: WiFi is only 2x2 MIMO - fine for browsing but limits local network transfers. The bulky case wastes space (I considered removing the board). No USB ports means no printer sharing or external storage.
Pro Tip: Don't lock ALL bands - leave some enabled for carrier aggregation to kick in during heavy downloads. My speeds spike to 150Mbps when CA activates!
Final Verdict: Despite minor quirks, this is the most stable LTE router I've used. Perfect for RVs, remote homes, or as a failover connection. Just passed its first summer heat test with flying colors!
