About This Guide
Introduction
This guide provides information for the WorryFree Wi-Fi Analyzer (WFW Analyzer) app (formerly
SmartMU).
NOTE: It is not recommended to set the Font size and Display size on the device to larger than the default.
Product Support
WFW Analyzer version 3.4.x is available on the following devices running Android Oreo.
• TC52
• TC57
• TC72
• TC77
• PS20
• EC30
• TC83
• MC93
• VC83
• L10A
• CC6000
Best Practices
For the best experience while using WFW Analyzer:
• It is not recommended to change the Font size and Display size on the device from the default.
Adjusting the Font size or Display size may cause the WFW Analyzer app to not display correctly.
• It is not recommended to use Multi-Window mode. Using Multi-Window mode may cause the WFW
Analyzer app to not display correctly.
• Ensure the primary user is logged into the device. The Android multi-user feature is not supported by
the WFW Analyzer app.
5
• Do not change the Wi-Fi settings on the device while actively using a WFW Analyzer feature. This
applies to the WFW Analyzer app or WFW Analyzer configuration using a Mobile Device Manager
(MDM).
• Packet capture and networking tools can run at the same time as another WFW Analyzer feature. This
applies to the WFW Analyzer app or WFW Analyzer configuration using an MDM.
• Do not run Ping using a short time interval if also running other WFW Analyzer feature(s) at the same
time. This applies to the WFW Analyzer app or WFW Analyzer configuration using an MDM.
• If the Connection Analysis feature is started using a staging tool or an MDM, do not start another
feature from the WFW Analyzer app until the connection analysis is complete.
• Each time the Connection feature starts, the device disconnects and then reconnects to the network.
When using this feature to analyze the Wi-Fi connection of a device and test the traffic of another app,
it is highly recommended to start the analysis feature before starting the other app. This prevents
interruption of the Wi-Fi connection during the test. Other WFW Analyzer features do not interrupt the
Wi-Fi connection.
• It is not recommended to toggle the Analyzer Activated switch while using a WFW Analyzer feature.
Toggling the switch resets the radio and interrupts the Wi-Fi connection.
Chapter Descriptions
Topics covered in this guide are:
• Using WFW Analyzer describes how to use the WFW Analyzer app.
• Configuration
• Packet Capture provides detailed information about WFW Security packet captures.
describes how to use the WFW Security app.

WFW Analyzer Use Cases
Analysis data provided by WFW Analyzer saves time and cost by allowing administrators to quickly
improve or mitigate performance issues. Actions may include reconfiguring the RF or WLAN system,
reconfiguring the device, or locating an issue that requires further investigation.
The following table describes some of the common WFW Analyzer use cases.
Table 1 Use Cases
Summary Detailed Description
Basic connectivity information. View the status of the connected device,
including the connected AP, RSSI,
channel, and IP/DHCP/DNS.
WiFi surveys and coverage from
the mobile device view.
WiFi connection analysis. On demand troubleshooting of initial and
Packet capture for off-line analysis
using a computer.
View multiple networks and access
points (APs) from locations within radio
frequency (RF) range of the device.
View connectivity and roam events.
Perform an auto reachability test from
connected APs to the gateway.
Verify the APs over-the-air advertised
data, retrieved directly from the
information elements of the AP packets.
