What is a WiFi analyzer?


With a WiFi Analyzer you are able to keep track of the status of your Wireless Network. Wireless Network analyzing helps you to maintain an overview of all your wireless connected devices. WiFi analyzing Software enables you to keep an eye over the device status, load, traffic, speed, WiFi usage, and signal strength of each router.


WiFi analyzer: keep an eye on the following 5 factors

 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

Device status

Are your routers always really online? Or are there repeatedly times when a router (and therefore your WiFi) is not available? With PRTG, you can monitor both uptime and downtime. To do so, simply use the SNMP System Uptime and Ping sensors from the PRTG sensor list.



WiFi disruptions often occur when the network load is too high. Among other things, the quality of your connection suffers. With the built-in bandwidth sensors of PRTG, you'll be able to identify the moments when the wireless network is most strained.



How many data packets travel over an access point? How much bandwidth is used by specific data? With SNMP traffic sensors or user-defined SNMP sensors such as the PRTG SNMP Custom Table sensor, you'll constantly stay up-to-date on the development of traffic in both your network and wireless network.

Signal strength

Signal strength

Do co-workers often complain about the WiFi connection in specific work areas or rooms? This could mean that the signal strength of certain routers is lacking. 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 of a corresponding device.

Last access

Last access

As an administrator, your job is to always keep an eye on the security of your network. Some devices, for instance, feature a parameter which displays the last time a device was connected and thus when it had last latched onto the wireless network. By applying user-defined SNMP sensors, you can observe, for example, if devices are available in the WiFi network at night - even when no staff is present. Conversely, you can also see the wireless network access points which are barely used and which could thus be moved or eliminated.

About SNMP for analyzing your WiFi with PRTG


PRTG uses SNMP, NetFlow and Packet Sniffing for its WiFi traffic monitoring. SNMP is supported by many router manufacturers, such as Cisco and Juniper, as well as several access point manufacturers. This makes setting up functional and reliable wireless network monitoring fast and easy.

AP Manufacturers

Meraki, NetGear, Aruba, Ruckus (Brocade), D-Link, and Extreme Networks are some of the access point manufacturers who support SNMP. In order to correctly monitor your wireless network, be sure to verify which protocol is supported by your access points.

Recommended reading

Meraki is an extremely popular access point manufacturer. Many administrators therefore have specific questions concerning the brand's products. Our knowledge base features a detailed article on how you can monitor your Meraki network with PRTG. Pull up the article here.

Analyze your WiFi with these sensors

The following sensors can be used for WiFi analyzing with PRTG:



Monitors various parameters using SNMP. See all SNMP sensors here.


The Ping sensor sends an ICMP echo request and can show the following:

  • Ping time
  • Minimum/maximum Ping time when using more than one Ping per interval
  • Packet loss in percent when using more than one Ping per interval

Ping Jitter

The Ping Jitter sensor sends a series of ICMP echo requests to the given URI to determine the statistical jitter. It shows the following:

  • Statistical jitter value
  • Execution time

Packet Sniffer

Monitors the headers of data packets that pass a local network using a built-in packet sniffer. It can show the following traffic types (analyzes only header traffic!):

  • Chat (IRC, AIM)
  • Citrix
  • FTP/P2P
  • Mail, WWW
  • Remote control (RDP, SSH, Telnet, VNC)

Packet Sniffer Sensor

NetFlow V5

Shows traffic for NetFlow V5-supported devices, split by type and is able to divide traffic into channels. Traffic types include:

  • Chat (IRC, AIM)
  • Citrix
  • FTP/P2P
  • Mail, WWW
  • Remote control (RDP, SSH, Telnet, VNC)

NetFlow V5 Sensor

NetFlow V9

Shows traffic for NetFlow v9-supported devices, split by type and is able to divide traffic into channels. Traffic types include:

  • Chat (IRC, AIM)
  • Citrix
  • FTP/P2P
  • Mail, WWW
  • Remote control (RDP, SSH, Telnet, VNC)

PRTG warns you of potential disruption to your WiFi

 iBandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps). It refers to the transmission capacity of a connection and is an important factor when determining the quality and speed of a network.

With PRTG you get much more

For many, wireless network monitoring is just one component of their monitoring structure. There can be many reasons for your Internet connection being down or disrupted.

With PRTG, you get a monitoring tool which features an extensive framework. This framework allows you to discover unconventional sources of errors, sources you may not have searched for right away. And that means you'll save precious time.


Here are four examples:

Internet accessibility

Internet accessibility

Does your Internet connection work only most of the time? Could the problem lie with your service provider, and not with your routers, switches, or access points? The Common SaaS sensor will provide you with the answer. This sensor queries various large sites such as Facebook, Dropbox, or YouTube, which in general are never offline.

disruption in email traffic

Disruption in email traffic

Nothing makes co-workers complain faster than the inability to send or receive emails. In such a case, the LAN or wireless network may be the culprit. But email issues could also be due to SMTP or POP3 protocol disruptions. PRTG features a variety of predefined and individually configurable sensors to monitor your mail server. Find our more in our sensor list.

website accessibility

Website accessiblity

The Cloud HTTP sensor monitors the load time of your site on a variety of servers found on different continents. This sensor lets you see if your site is also accessible from abroad. Tokyo, Ireland, North Virginia, and Oregon are a few of the places where these servers are found.



PRTG monitors the status of your firewall and informs you immediately in the event of a crash. This enables you to promptly take action to restore the security of your system.


gerald schoch

Practical tip: “Hey Gerald, what would you tell administrators looking to use PRTG as a NetFlow Analyzer?”

“Cisco has continuously developed the NetFlow technology. Administrators must therefore find out beforehand which NetFlow version is supported by their routers and switches. With the right PRTG sensors, setting up NetFlow monitoring is quick and easy.”

Gerald Schoch, release manager at Paessler AG

LAN, WIFI, WAN – PRTG keeps an eye on everything

LAN Monitoring

LAN Monitoring

LAN monitoring is the basis for a reliable, high-performance network. Many administrators still think they can do without a monitoring tool. But after a disruption or crash, these same administrators often search frantically for good monitoring software. Other administrators use several monitoring tools concurrently but eventually opt for PRTG to benefit from a single, central, efficient, and easily upgradeable tool.

WiFi Network Monitoring

WiFi Network Monitoring

These days, many businesses and organizations operate on the "bring your own device" principle. Tablets, smartphones, printers, and other mobile devices must however also be granted access to the WiFi network. Furthermore, laptops are often used for presentations in conference rooms and likewise require an Internet connection. As a result, WiFi monitoring quickly becomes an important issue for administrators.

WAN Monitoring

WAN Monitoring

Wide area networks are especially susceptible to crashes and disruptions, for they are spread out across rooms, countries, and even continents. Since a great deal of important data (such as internal applications, emails, and VoIP telephony) flows across a WAN, WAN monitoring can therefore truly be a lifesaver.
