Monitoring and analyzing Wi-Fi networks is a critical move to keep up with speed and security. A hacker can also create an Evil Twin AP, an attack that masquerades a trusted AP by displaying the SSID to lure victims. Hackers can perform Wi-Fi attacks by setting up an insecure Rogue AP inside the network that creates a backdoor into a trusted network.

We haven't even discussed physical barriers such as Concrete walls, Wood, Brick, Plaster, Glass and other common building materials that further impede signal strength and Network throughput.īut signal noise and interference is not always the worst enemy of Wifi.

Microwave ovens, Bluetooth devices, Baby Monitors, Wireless Home Phones are some of the devices that can interfere with your Wi-Fi signal and weaken it. There are so many other devices that use similar Radio Frequencies “RF” as Wi-Fi. People using the technology in closed places like buildings, usually suffer from congestion due to overlapping Wi-Fi signals, Walls, Microwaves and other signal interfering items.Īt times, neighboring Access Points (APs) are using the same frequency range which causes a decrease in wireless speed and performance as well. Wi-Fi can be inconsistent and laggy at times due to external factors that you cannot always control. It is more important than ever as an IT Admin and Engineer to understand what is going on in your network, especially on your Wireless network – this is where a Wifi Analyzer comes into play. There has been a dramatic increase in the devices that connect to the Internet using Wi-Fi and in 2016 alone, more than 15 billion Wi-Fi devices were shipped around the world.Īnd with the rise of Internet of Things (and not just mobile phones or TVs), but smart home devices like refrigerators, thermostats, speakers, security cameras and even light-bulbs, Wi-Fi is going to dominate airwaves.

Today it is common to have Wi-Fi access not only in homes, coffee shops, hotels, airports – but also in actual Airplanes and Subways. Wi-Fi is changing the world as we know it – many of us cannot live without it if we're being 100% honest with ourselves.
