Which router features matter most when uptime is more important than headline download speed?

When uptime matters, look first at recovery and management features. Useful capabilities include automatic WAN-to-cellular failover, dual SIM support, link health checks, a hardware or software watchdog, scheduled or remote rebooting, event logs and alerts. External antenna connections and good signal diagnostics can be more valuable than a higher theoretical speed, especially at a fringe-coverage site.

The router also needs the right power input, operating-temperature range, Ethernet ports and security options. Ask how failover is triggered, how long it takes, how the router returns to the primary service and whether active sessions will be interrupted. Remote access and fleet management reduce the chance that a simple fault becomes a site visit. Headline download speed is still relevant, but a slower connection that is monitored, recoverable and correctly installed will usually be more useful than a fast connection that quietly fails.
