Nowadays, the customer uses a device that requires wireless connectivity either outside or inside the house. The customer usually relies on the device indicator that refers to the received signal strength indicator (RSSI). On the device, the RSSI is designated as bars rating the Access Point (AP) signal strength for the customer. Most customers of WiFi devices will check the AP signal quality indicator before they connect to the AP. However, the RSSI can be confusing to the customer. This is because customers often associate the Wi-Fi performance with RSSI, with the perception that the higher RSSI, the better performance of data transmission. This perception somewhat true, however, sometimes that perception can be denied by interference, such as electromagnetic signal, congested frequency by others AP, and congested traffic by other devices connecting to same AP. Therefore, this paper proposed a new indicator to provide a real guidance to the customer, which introduce signal quality indicator which combine actual RSSI and WiFi performance, such as latency and loss to represent the actual performance of the AP. Based on the observed data latency, loss and RSSI, we perform a regression analysis for curve fitting. The result shows that the proposed signal quality indicator is better than the actual RSSI rating bar to reflect the Internet experience.
