How does the Wi-Fi packet sniffer work in NPM?.When you know what you’re looking for or suspect only a particular application is responsible, a Wi-Fi network sniffer’s filtered mode helps make troubleshooting faster. For example, when a wireless sniffer is in filtered mode, it will only capture packets that fit within the user’s pre-selected parameters. Wi-Fi packet sniffers can also contain settings for network administrators to select exactly how much network traffic they want to capture and analyze. This can make it easier for administrators to pinpoint the root cause of wireless performance issues and support the ability to fix Wi-Fi issues quickly. Since data and metadata are unintelligible to humans in their raw state, Wi-Fi packet sniffers are built to decode network packets by transmuting them into a readable format. Wi-Fi network sniffers work by crawling across a wireless network to intercept a wide range or a small subsection of data packets as they pass through the network, gathering information about those packets, and using the information to provide insights into what’s going on in a network. Wi-Fi packet sniffers are designed to include key monitoring metrics specifically for wireless networks to provide comprehensive performance visibility.

For administrators in an enterprise that predominantly uses wireless networks, using a traditional sniffer tool instead of a wireless sniffer software might not be agile or expansive enough to meet these needs. Also, wireless networks may involve numerous access points, adapters, and routers, while a wired network does not. For example, wireless networks may be more susceptible to packet loss because data is traveling through the air between two distant points, which can cause data to get lost in translation. Wireless networks often require a different approach to packet sniffing than the standard approach for wired networks. A Wi-Fi sniffer can also be referred to as a wireless packet sniffer or a wireless network sniffer. Wireless sniffer solutions are built to capture wireless network traffic and analyze it to generate insights into what’s going on in a network at any given time.

This is the lowest possible value that will make a connection between the router and computer, but it's too weak to be useful for any online service. This is the lowest value that will deliver acceptable results for most online services. Anything from -30 dBm to -50 dBm is excellent and is often about as high as you can get. This is the maximum signal strength you could achieve, and it probably means you are within a couple feet of the Wi-Fi router. Here are some guidelines for assessing your signal strength:
