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.

Features

The packet capture feature saves incoming and outgoing 802.11 data traffic that is handled by the WiFi
stack in its current 802.11-STA role on a device that is connected, or attempting to connect.

• Includes device specific internal outgoing packet attempts and incoming packets.

• Includes broadcast/multicast traffic sent from an access point to connected devices.

• It is not sniffing in receive-only/promiscuous mode like over-the-air sniffers.

WFW Analyzer internal packet captures are:

• Unaffected by the current channel or frequency used by the antenna. Traffic from supported packet

types is automatically captured on any channel to which the device connects, roams, or while scanning
