After setting up a VSAT system, thorough testing ensures reliable performance. Begin with a signal strength test to confirm proper antenna alignment. Perform speed tests to check internet connectivity and latency. The modem should display optimal signal indicators, and the connection should be stable without frequent disconnections. If issues arise, check cable connections, restart the modem, or reconfigure network settings. Testing also includes verifying data transmission and response times under different weather conditions. If signal loss or interruptions occur, adjusting the antenna position or consulting the service provider can help resolve performance-related concerns.
