Knowing immediately when there is a severe problem can often mean the difference between getting a problem resolved quickly and causing a disaster on the business' front lines. While email is the primary way most of these notifications work, today's plethora of online collaboration technologies can give you many more options, and all these tools should support at least some of them. Vendors need to specifically support the ability to detect and monitor hypervisor environments and their virtual machines, many of which bring their own challenges. For example, VMware ESXi has a free tier called ESXi that doesn't include the company's vSphere management environment. Being able to support ESXi without this is a huge bonus, unless you're using both it and vSphere anyway. Also very important these days, especially now that so many networks are being managed remotely, is the ability to support virtualized infrastructure and software-defined network environments.
Some enterprises may not want to work with Wireshark due to the product’s niche focus on protocol analysis. Depending on who in your organization is using the WiFi analyzer and how they’re using it, you’ll want to keep in mind the user interface of the different tools you’re considering. Some WiFi network analyzer tools focus on user-friendly dashboards and reporting capabilities, but some of the open-source and developer-facing options can be more difficult for users to navigate. Many of the software options on this list are available in both business and personal use packages, so it’s important that you look closely at the included features of the software you’re considering.
Best Wi-Fi Analyzers and Free Wireless Scanners
Paessler PRTG This monitoring package is a bundle of monitors, which are called sensors. One sensor, called a packet sniffer, notes packet header contents but does not capture them. Nmap uses a discovery feature to find hosts in the network that can be used to create a network map. Network admins value it for its ability to gather information from the host about the Operating System, services, or ports that are running or are open, MAC address info, reverse DNS name, and more. If you want fixes any faster than twice a year, you’ll have to pay for them.
NetworkMiner is a fascinating tool that falls more into the category of a forensic tool rather than a straight-up network sniffer. The field of forensics typically deals with the investigation and collection of evidence and Network Miner does that job well for network traffic. Much like WireShark can follow a TCP stream to recover an entire TCP conversation, Network Miner can follow a stream to reconstruct files that were sent over the network. One of the most useful tools Wireshark provides is the ability to follow a stream. It’s probably most useful to think of a stream as an entire conversation.

Wireshark can be used to determine source and destination information as well as packet type data and other multi-protocol analytics. You’ll need to contact ManageEngine for a quote, as subscription and licensing prices for this tool differ based on the needs of your business. This NTA supports a wide variety of network hardware including devices from Cisco and HP. What I like also about this option is its support of Vmware vSphere distributed switch.
Critical network information that cannot be gleaned from the metadata can be discovered in this way. Tools like those provided by SolarWinds can provide more meaningful data than simply traffic flow. The tool that is more relevant to this article is the Deep Packet Inspection and Analysis tool.
Why Does Network Analysis Matter?
As tougher testers tend to cost much more, I suggest that you get a device particular to your needs. If you’re always on the field, then you might want to get a tester that’s tough and made with durable materials, preferably a tool made with materials that could withstand falling impact, dust, and surges of electricity. All in all, this affordable product is well-made, well-built, and is a reliable piece of tool that can help you in your network cabling tasks. By and large, this is a reliable product that can competently perform diagnostics and continuity checks without failure. This is a game-changing tester that can be a substantial addition to your work arsenal. I also appreciate that the Rj11 and RJ45 connector tips of the tester come with port covers, protecting them from damage caused by debris and particulates.
Identifying and establishing baselines help admins quickly spot and address bottlenecks and avoid downtime, and can also help them tackle security issues the moment they arise. Made by Paessler, PRTG Network Monitor is a useful network performance monitoring tool with Wi-Fi analysis capabilities. Like both SolarWinds NPM and NetSpot, PRTG discovers network devices and routers to build a map. This visualization tends to be too cluttered to be immediately useful; however, PRTG collects a good deal of data to inform Wi-Fi troubleshooting. NetSpot is one of the most popular WiFi network analyzers on the market for both personal and business use, featuring one of the most user-friendly and moldable interfaces for network data visualization. Discovery mode provides a snapshot of WiFi networks in your vicinity, while survey mode offers heat maps that survey details such as WiFi strength.
Using WiFi network analyzer software, you can easily create a snapshot of your network’s data performance and identify which WiFi channels are performing at optimal levels. Some tools also offer suggestions via data visualization, helping you to solve problems like optimized server location. Check out some of the top WiFi network analyzer software options below, and take one step closer to total network visibility and optimization. For each application we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources. With extensive experience working as an electrician, I can confidently say that Elegiant’s network cable tester is among the best tools to test cord connections. I came across this product while working on a LAN connection set-up for a local company.
Look at my list of the top 10 log sources you should keep your eye on. PCMag.com is a leading authority on technology, delivering lab-based, independent reviews of the latest products and services. Our expert industry analysis and practical solutions help you make better buying decisions and get more from technology. Once you have that list of essential requirements, you should be able to look at each one of these products and determine if they qualify. If more than one product qualifies, you'll need to do some testing on your own to see which one best suits your needs. That's where a free evaluation version is important, and you're looking to access it for 30 days at least.
This is a great option for new or small businesses or non-profit organizations who need an effective means to monitor network traffic and find bottlenecks and other issues among their network. Basically, Network Traffic Analyzer tools provide you with visibility inside your network to identify what applications are being used, possible misuse of the network by employees or malicious traffic and much more. Unlike NetSpot and NetCut, WiFi Analyzer is intended primarily for home or temporary use. It comes in basic and pro versions, and the basic version includes everything you need to analyze your Wi-Fi network. The app takes your network and turns the data into easy-to-understand visualizations, suggesting which channel you should use to reduce congestion. NetCut allows you to monitor LAN activity and can display all the IP and MAC addresses and data of devices that are connected or have ever connected to your network.
Before something becomes a problem, look into implementing network analysis and Wi-Fi monitoring software. As your network grows, you’ll thank yourself for having set things up correctly, and you’ll find your troubleshooting time-to-resolution is much faster, preventing issues from reaching your employees, clients, or end users. NTA is a specialized Wi-Fi and network traffic analysis tool that can be added onto SolarWinds NPM to extend its NetFlow monitoring capabilities. These two tools are commonly used together, so SolarWinds created a bundle of both NPM and NTA it calls Network Bandwidth Analyzer Pack . A specialty of BAP is its ability to help pinpoint which users are hogging bandwidth or if particular apps are eating up your network capacity. There are numerous network analysis tools and software on the market, each with its own features and focus.
