Reason: Signal strength and quality are the most likely cause of slow speeds/low throughput. NOTE: The FX3100 is configured by default to use the best connection available, so low throughput is rarely related to configuration.
Solution: Check the signal strength and quality reported by your FX3100:
Access the FX3100 Admin web UI and navigate to About > Diagnostics to check the values for Signal Strength (RSRP) and SNR.
If the signal is poor, relocate your FX3100 to improve signal conditions. If the signal is good, but throughput is slow, check your service provider’s network conditions for outages and expected performance.
