People used to connect to a WiFi network only with a laptop; now, they are bringing all their WiFi-enabled gadgets into the wireless environment, including their smartphones, TVs, smartwatches, speakers, etc.
To make matters more complicated, business policies such as BYOD (Bring Your Own Device) allow users to connect freely to a network.
All of these devices slow down a network making browser speeds crawl and surfing the net or performing online tasks slow.
Not only does it slow down the network, allowing access to a wide range of devices can also put your WiFi clients and AP's at risk.
Here is our list of the top wifi analyzers:

Hackers can install rogue AP's or crack your security encryption with the help of sophisticated hardware sniffers.
And if you think your wireless stays within your building, think again, you might have lots of signal leakage which allows a hacker to war-drive your network.
Knowing where your signals are, and the neighboring APs is key to keeping your network secure.
With the right site survey or stumbler tool, you can solve these issues pretty easily.
Finding why your AP's are having a bad day can be as simple as changing a channel or moving an object that creates interference.
A proper penetration tester can also help you identify where your weak security spots are, and improve them accordingly.
In this article we will be covering 25 tools which are a mix of top control and traffic analyzers, security auditors, and monitoring tools to help you narrow down issues and security flaws in your network.
