Diagnosing and evaluating Wi-Fi quality
Wi-Fi quality can be quickly diagnosed using the new Acrylic Wi-Fi Professional v2.3 network diagnosis functionality. With this new version, when monitoring the available Wi-Fi networks, you will be able to select an access point to visualize the many parameters affecting Wi-Fi quality on the “Network Quality” window, including network security aspects.
Wi-Fi Quality Controls
- Channel quality: Interferences have a negative impact on Wi-Fi quality. The more networks operating on the same channel, the more interferences each one will experience, causing frequent disconnections and packet loss on connected client devices.
- Signal strength: Signal strength is one of the factors that affects Wi-Fi quality. In order to achieve good transmission speeds, one of the factors the should be analyzed is the wireless connection signal strength.
- Link quality (SNR): Signal quality is a value ranging from 0 to 100, which considers, along with signal strength, the noise generated by interference sources. A network can be received with a very good signal strength, but at a not so good quality.
- Wi-Fi security: Is your Wi-Fi network secure? We give you a few recommendations to improve your Wi-Fi network security and prevent unauthorized access attempts that could potentially decrease your wireless network performance quality.
- Transmission speed: Each device can support a variable number of speeds. Know how fast the maximum connection speed supported by your access point is, and identify whether your settings should be changed or your hardware upgraded or replaced for better results.
- Wi-Fi network standard: Each new Wi-Fi network standard revision includes improvements that increase connection quality and speed. The use of old standards will diminish network performance. 802.11n or 802.11ac standards should be used in order to enhance the user experience.
- Packet forwarding: When no connection confirmation from a client device is received by an access point, packets are forwarded. The higher the number of forwarded packets, the more saturated a Wi-Fi channel will be, resulting in reduced band width. A high packet forwarding rate has a negative impact on Wi-Fi network quality, and it could result from hardware failure or a bad location of the access point in areas with signal interference or shielding.
