Why Does My FWA710 Router Keep Disconnecting Frequently?

The issue is related to poor radio quality (low SINR values), not insufficient signal strength. High interference in the environment can cause these symptoms:

• Unstable throughput
• Increased latency and jitter
• Packet loss and retransmissions

Steps to Improve Connection Stability:

1. Reposition the Router: Move the device to a higher location or adjust its orientation toward the nearest base station. Even small changes can improve SINR.
2. Check RF Conditions: Log in to the router’s interface to review real-time RSRP, RSRQ, and SINR values. Persistent low SINR (close to or below 0 dB) confirms RF interference.
3. Test Different SIMs or Carriers: This can identify if the issue is ISP-related.
4. Experiment with Band Locking: Configure the router to lock onto specific bands (e.g., 5G or LTE) for stability.
