Optimal internet access is essential to support digital-based learning at SMK SWADHIPA 2 Natar. However, unstable network quality often hinders the smooth delivery of learning content. This study aims to evaluate the quality of the school’s internet network by applying Quality of Service (QoS) measurements. The research method involved measuring QoS parameters based on TIPHON standards, including throughput, jitter, packet loss, and delay. The results indicate that the application of QoS using the Simple Queue method produces unsatisfactory throughput values.According to TIPHON standards, throughput in classrooms was recorded at 14 Mbps, in vocational practice rooms at 8 Mbps, and in theadministration and teachers’ offices at 20–21 Mbps, all of which fall into index 1 (poor). These findings demonstrate that the internet networkquality at SMK SWADHIPA 2 Natar remains suboptimal and requires further improvement to support learning activities effectively.
