Abstract

The use of internet or wifi networks in office buildings causes a lot of interference, both from the same access point channel, from the distance range of the access point to the user, even the access point itself. For this reason, how to solve this problem, firstly in the installation of the access point, it is necessary to check the conditions in the field, both from measuring the distance of the access point throughout the room, checking the distance between access points and checking radio channels between access points. By checking the network requires a wireshark application for measuring network quality or Quality of Services (QoS). Parameters measured are throughput, packet loss, delay and jitter. Parameter results with good network conditions at a distance of 5 meters obtained an average value of 163.66 kb/s throughput, 0.03% packet loss, 4.66 ms delay, 4.66 ms jitter, and good network parameter results at 14:00 – 17:00, the throughput value is 2105 Kb/s, 0% packet loss, 3.998 ms delay, 4.011 ms jitter, From the test results, it can be concluded that the farther the distance from the user to the access point, the smaller the throughput value, because the data sender will look for a close recipient first, then the remote recipient and is influenced by the number of network users themselves. Keywords : Access Point, delay, interference, jitter, QoS, packet loss, throughput, Wifi, Wireshark Penggunaan jaringan internet atau wifi pada gedung perkantoran banyak sekali terjadi interferensi baik dari saluran access point yang sama, dari jangkauan jarak access point ke pengguna, bahkan access point itu sendiri. Untuk itu cara mengatasi masalah tersebut, pertama dalam pemasangan access point diperlukan pengecekan kondisi dilapangan baik dari pengukuran jarak access point keseluruh ruangan, pengecekan jarak antar access point dan pengecekan saluran kanal radio antar access point. Dengan pengecekan jaringan tersebut memerlukan aplikasi wireshark untuk pengukuran kualitas jaringan atau Quality of Services (QoS). Parameter yang diukur berupa throughput, packet loss, delay dan jitter. Hasil parameter dengan kondisi jaringan yang baik di jarak 5 meter diperoleh nilai rata-rata throughput 163.66 kb/s, packet loss 0.03%, delay 4.66 ms, jitter 4.66 ms, dan hasil parameter jaringan yang baik jam 14:00 – 17:00, diperoleh nilai throughput 2105 Kb/s, packet loss 0%, delay 3.998 ms, jitter 4.011 ms, Dari hasil pengujian diperoleh kesimpulan bahwa semakin jauh jarak pengguna user ke access point maka nilai throughput yang didapat semakin kecil, karena pengirim data akan mencari terlebih dahulu penerima yang dekat setelah itu baru penerima yang jauh dan dipengaruhi oleh banyaknya pengguna jaringan itu sendiri. Kata Kunci : Access Point, delay, interferensi, jitter, QoS, packet loss, throughput, Wifi, Wireshark
