Getting Started with Mojo Packets

Step 1 - Capturing a Packet Trace

To start analyzing issues in your Wi-Fi environment, you first need to capture a packet trace. Here are the steps for various environments:

Step 2 - Uploading a Trace File to Mojo Packets

Once you have the trace file, the next step is to upload the trace file to your Mojo Packets account. There are a couple of ways in which you can upload a trace to Mojo Packets:

Mojo Packets UI

Log in to your Mojo Packets account using your credentials. You are now on the Upload page and can upload trace files by clicking ‘Select Files’ or just drag-and-drop a file in the area marked on the page.

Mojo Packets Wireshark Plugin

Our Wireshark plugin enables you to upload a trace directly from the Wireshark application. The steps for installing and using the plugin are outlined in the Plugin User Guide.

Step 3 - Analyzing the Trace Dashboard

You now have the traces on Mojo Packets, so let’s start analyzing them. On clicking a trace file, you are redirected to the Dashboard. The purpose of this dashboard is to give you a holistic view of your network, for connectivity as well as performance. It helps you quickly drill down to the problematic client(s), thereby reducing the MTTR.

Understanding Parts of the Dashboard

Connectivity Tab

This tab is opened by default when you click a trace file.

Clients and Access Points Tabs

These tabs provide statistical data about packets sent from or received by clients and access points.

        

Step 4 - Analyzing a Specific Client

Once you have identified the client that has the problem, you can click on the client and view its “trace visualization”. Purpose of this view is to help you quickly identify the problematic frame(s) in the trace.

Frame View

Frame view has been designed is such a way that you can instantly start identifying problematic frames in a connection handshake.

  1. The graph is dynamic in nature and each bullet on the graph represents a frame in the trace. Frames corresponding to only the selected client are displayed on the graph.
  2. You can hover over the bullets to see a tooltip which displays more information about that particular frame.
  3. The X-axis shows the actual frame number of the frame as captured in the trace. The Y-axis corresponds to the different logical levels as assigned to the different frame types/sub-types.

Frame List

The Frame List table displays a summary of the trace which has been generated based on the selected client or access point. This summary contains only those frames which correspond to the selected Client / AP MAC and they help in understanding the handshake patterns in the trace. The frames present in the summary are the ones which are depicted on the graph.
