Signal drops during peak hours
Stabilize connectivity under load.
Updated Feb 9, 2026
Overview
Connectivity problems often involve weak signal, SIM issues, or APN configuration. Stabilize connectivity under load.
Diagnostics
- Check signal strength and last heartbeat time.
- Verify SIM status and data plan.
- Review APN settings in the portal.
Resolution steps
- Move antenna outside metal shielding.
- Power cycle and reseat the SIM.
- Reconfigure APN and retest.
Preventive maintenance
- Document signal strength by location.
- Avoid placing units in shielded corners.
- Recheck connectivity after firmware updates.
When to contact support
- No signal after antenna relocation.
- SIM is active but device stays offline.
- Repeated disconnects in stable locations.

Expanded guidance
- Confirm all steps are documented so the next technician can reproduce the results.
- Capture before/after metrics (errors cleared, sales restored, or uptime improved).
- Review machine, reader, or route settings to ensure they match location standards.
Common pitfalls
- Skipping a controlled test leads to false positives.
- Updating hardware without documenting configuration changes.
- Forgetting to verify payout, refund, or reconciliation data after changes.
Next-step checklist
- Run a final test with known-good inputs.
- Log the outcome with date, time, and device identifiers.
- Schedule a follow-up check if the location has high traffic or seasonal demand.
