After struggling with flaky Netgear units that dropped connections like bad habits, the Cudy LT18 became my unexpected hero. This isn't just another router - it's the Swiss Army knife of mobile connectivity that survived 110°F RV storage days while keeping my solar monitoring alive.

The band locking feature is pure magic. While other devices stubbornly clung to congested towers near an amusement park, I manually selected less crowded LTE bands and watched speeds jump from 20Mbps to over 100Mbps. Those detachable SMA antenna ports? Lifesavers when paired with my Peplink rooftop antenna - suddenly weak signals in wooded areas became usable connections.

Living in an RV taught me to appreciate small details: The physical power button (no more awkward cord yanking), dual SIM slots for automatic failover between carriers, and that clever WAN/LAN port that transforms based on my needs. I've wired it directly into my 12V system using a $3 cigarette lighter adapter - try that with your fancy USB-C PD routers!

Is it perfect? The internal board rattles in its oversized case like a pea in a drum, and the WiFi antennas are permanently attached (though I hacked in RP-SMA connectors). But when you're streaming Netflix during a thunderstorm while parked deep in the woods, those become charming quirks rather than dealbreakers.

Five months later, it's still humming along while more expensive routers gather dust. The recent addition of Cudy's mesh-compatible AX1800 extender eliminated my basement dead zones. Carrier aggregation remains mysterious - sometimes it boosts to 150Mbps unexpectedly - but at this point, I've stopped caring because it just works. For mobile warriors who need reliable internet anywhere, this unassuming box delivers where premium brands failed me.
