With our Wi-Fi analyzer PRTG, you can easily keep track of the status of your wireless network and maintain an overview of all devices connected via Wi-Fi. Wi-Fi traffic monitoring, Wi-Fi bandwidth monitoring, Wi-Fi usage monitoring, analyzing network speed and the signal strength of each router – PRTG has got you covered.
PRTG offers built-in sensors with which you can monitor your wireless network effortlessly. Our automatic network discovery feature intelligently creates a set of sensors for the devices it finds in your network after the initial installation. This saves you valuable time and makes setting up PRTG a breeze.
Whether there’s an issue with your wireless devices, routers, or any other problem in your network – PRTG will immediately alert you of the issue via customizable notifications. Set, for example, individual error thresholds that trigger alerts, configure detailed alerting rules, and select your preferred notification method, such as email, SMS, or push notifications.
Are there areas in your buildings with a bad Wi-Fi signal? What is the average Wi-Fi bandwidth? Ask yourself these questions to find out, for example, if a complete network upgrade is necessary or if a more efficient distribution of existing resources might be sufficient. PRTG can give an answer to all these questions with the help of its detailed, customizable maps, dashboards, and historical data.
LAN monitoring is the basis for a reliable, high-performance network. This is why it’s important to keep an eye on your workstations, routers, switches, servers, bandwidth & more at all times and detect connectivity issues and performance bottlenecks as early as possible. Check out LAN monitoring with PRTG.
Today, it’s not uncommon to bring your own mobile devices to the office and connect them to the company network via Wi-Fi. In addition, laptops are often used for presentations in conference rooms and likewise require smooth Wi-Fi access. As a result, wireless network monitoring quickly becomes an important issue for administrators.
Wide area networks are particularly susceptible to crashes and disruptions because they are distributed over buildings, countries, and even continents. At the same time, lots of important data (such as emails or VoIP telephony/) flows across a WAN. Getting started with monitoring can therefore truly be a lifesaver. Check out WAN monitoring with PRTG.
PRTG comes with more than 250 native sensor types for monitoring your entire on-premises, cloud, and hybrid cloud environment out of the box. Check out some examples below!
The SNMP Custom Advanced sensor monitors numeric values returned for object identifiers (OID). It can show the following:
The Ping v2 sensor sends an Internet Control Message Protocol (ICMP) echo request ("ping") from the probe system to the parent device to monitor its availability. It can show the following:
• Response time
• Packet loss
• Target status
• Minimum and maximum ping time
The Cloud HTTP v2 sensor monitors the loading time of a web server via HTTP from different locations worldwide (Asia Pacific: Singapore, Asia Pacific: Sydney, Europe: Ireland, US East: Northern Virginia, US West: Northern California) via the PRTG Cloud. It can show the following:
The SMTP&POP3 Round Trip sensor monitors the time it takes for an email to reach a Post Office Protocol version 3 (POP3) mailbox using the Simple Mail Transfer Protocol (SMTP). It sends an email using the parent device (an SMTP server) and then scans a dedicated POP3 mailbox until the email comes in. It can show the following:
See the PRTG Manual for a list of all available sensor types.
Real-time notifications mean faster troubleshooting so that you can act before more serious issues occur.
There can be many reasons why your internet connection is down or not very reliable at all. This makes it all the more important that wireless network monitoring is always only one component of your entire monitoring setup. Check out other aspects that you should keep an eye on when monitoring your IT infrastructure.
Does your internet connection work only most of the time? The problem could actually lie with your service provider and not with your routers, switches, or access points. Use the Common SaaS sensor to monitor websites like YouTube which are usually never down to keep an eye on internet connectivity.
Nothing makes co-workers complain faster than if they can’t send or receive any emails. In such a case, the LAN or wireless network may be the culprit. However, email issues can also occur due to problems with SMTP or POP3. PRTG includes a variety of preconfigured mail server monitoring sensors, for example, the SMTP&POP3 Round Trip sensor.
A website that loads very slowly or an online shop that’s not reachable at all can quickly become business-critical and more often than not results in money loss. The Cloud Ping v2 and the Cloud HTTP v2 sensor make sure that your websites are available from all around the world.
Custom alerts and data visualization let you quickly identify and prevent Wi-Fi issues.

A Wi-Fi monitoring tool, or Wi-Fi analyzer, is a software application used to analyze and optimize wireless networks, specifically those using the Wi-Fi protocol. It provides detailed information about the Wi-Fi signal strength, network congestion, channel interference, and other factors that affect the performance of a wireless network.
By using a Wi-Fi analyzer & monitoring tool, you can:
Wi-Fi monitoring is crucial because it allows you to ensure the optimal performance and reliability of your wireless network. By monitoring Wi-Fi, you can identify and troubleshoot connectivity issues, detect interference sources, monitor network usage, and ensure proper bandwidth allocation. It helps in maintaining a stable and efficient Wi-Fi environment for users and makes sure that potential problems are identified and resolved promptly.
PRTG helps you detect and resolve a wide range of Wi-Fi issues. Some common problems that can be identified include:
PRTG provides real-time data and historical analysis, which enables administrators to pinpoint the root causes of problems and take appropriate actions.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
