Wi-Fi monitoring with PRTG: Keep an eye on the following 5 aspects


 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Device status: Is your hardware available?

Are your routers really online at all times? Or are there times when a router (and thus your Wi-Fi) is repeatedly not available? With Paessler PRTG, you can monitor both uptime and downtime – simply set up sensors like the SNMP Uptime v2 sensor or the Ping v2 sensor, for example.

Load: Is your wireless network strained?

Wi-Fi disruptions often occur when the network load is too high, which means that the quality of your connection will suffer. With the preconfigured bandwidth sensors in PRTG, you can quickly identify the moments when your wireless network is most strained and adapt your capacity planning accordingly.

Traffic: Who is using your bandwidth?

How many data packets travel over an access point? How much bandwidth is used by specific data? With the SNMP Traffic sensor or the SNMP Cisco ASA VPN Traffic sensor, for example, you'll stay up-to-date on your Wi-Fi traffic as well as all other network traffic.

Signal strength: Are there weak spots in your building?

Do co-workers often complain about the Wi-Fi connection in specific office areas? This could mean that the signal strength of certain routers is not what it should be – eventually, you will need to replace routers or invest in additional access points. A neat way to check the signal strength of your wireless network with PRTG is to query it with an SNMP Custom Advanced sensor.

Last access: Which devices are used when?

To always keep an eye on network security, set up custom SNMP sensors and check the last time a device was connected to the wireless network. This way, you can make sure that no unauthorized access takes place, particularly during out-of-office hours. The collected data is also helpful to analyze overall WiFi usage over a longer period.


What Wi-Fi monitoring looks like in PRTG

Diagnose issues with your wireless network by continuously monitoring your devices, bandwidth, and availability. Show Wi-Fi usage in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot your Wi-Fi issues.

4 reasons why PRTG is the Wi-Fi monitoring tool of your choice

Monitor status & performance of your wireless network

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.

Set up Wi-Fi monitoring fast with preconfigured sensors

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.

Receive customizable alerts and notifications

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.

Visualize & analyze your Wi-Fi network on custom dashboards

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, Wi-Fi, WAN – keep an eye on your entire network connectivity with PRTG

LAN monitoring

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.

Wireless network monitoring

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.

WAN monitoring

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.

More than just a Wi-Fi monitoring software: Maintain a reliable IT infrastructure with PRTG

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.

Internet accessibility

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.


Disruptions in email traffic

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. 

Website availability

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.
