A Three Step Guide For Finding WiFi Connectivity Issues In 2 Minutes

Guess who just resolved WiFi connectivity issues?

WiFi is great, until…

You are a chill network admin doing real admin stuff 😉, until a few employees start complaining that the WiFi isn’t working. Turning WiFi ON and OFF ain’t working and you know it is about time you dive into the tedious task of finding out WHY IT IS NOT WORKING.

We all have been through this. Even the thought of debugging a WiFi issue is frightening enough, let alone fixing it.

You can always use some help, but…

Yeah I know you got this covered. So what if your WiFi is not connecting, you can always take a packet trace. Open it in Wireshark or a similar tool and you will know what the issue is, right? ...ahem... Right?

Yes Sir, it doesn’t work that way. There are always these 4 burning questions :

  • How many devices are facing connectivity issues in the network?
  • What type of failures are occurring in the network?
  • Whether the issues are with the clients or the APs?
  • Knowing identities of clients which are facing issues in your network.

Even if you are hell bent on finding all the answers, you know it requires a lot of time and patience to get to them.

It’s about time, packet trace analysers got smart !

Wouldn’t it be really nice, if you could throw your packet trace to a tool that would quickly let you know all the answers to those burning questions?

That’s precisely what Mojo Packets aims to do through its improved Connectivity Analysis.

A three step, 2 minute analysis of those thousands of frames will give you all the answers to your WiFi connectivity problems:

Step 1: Upload the trace capture (duration : 30 seconds)

Drop the trace on Mojo Packets’ Home page and the file starts getting processed in the cloud. Click on it and the Analyze dashboard pops up.

Step 2: Analyze Client Connectivity Timeline (duration : 30 seconds)

Most of the questions are answered here in one glance -

Observe all connections in a network, on a time scale
  • X axis represents the time scale of the packet trace.
  • Y axis captures the clients which were present in the network.
  • Red bars denote failed connection attempts.
  • Green bars denote a perfectly fine working WiFi connection.

The ingenious design of this graph helps you find answers for the above mentioned questions:

  • The number of devices that are facing connectivity issues in the network.
  • Identities of clients which are facing issues in the network.
  • Types of failures that are occurring in the network.

Once you have identified the client(s) of concern, a click on it will lead you to the next step in finding the remaining answers.

Step 3: Analyze Client Connection logs (duration : 1 minute)

Mojo Packets automatically detects for you when a client tried to connect to WiFi and what happened to that attempt.

In brief, this table aims to reveal information about clients’ connection attempts like access point, SSID, channel number, reason why connection ended, frame and time range of connection etc.

Table representing connection events in a trace

All of this information at one place is very convenient from a troubleshooting perspective. What’s even better is that this table is extensively customizable:

  • By default all connection logs are grouped by Connection End Reason, but you can always group them the way you like, be it by SSID, Client, Channel or even combination of them.
  • You can play around with these connection logs using different filters to analyze failure patterns. You can check whether they are affecting all clients or some clients in isolation.

With some creative use of the filters, you can answer one more question: whether the issue is with Client or AP.

So that’s how quick and easy it really is to find out the actual problems in your network without wasting a complete day on it.

One more thing,

Frame Visualization

Once you narrow down to the culprit device(s), you may also want to know the frame level details. For that, Mojo Packets has Frame Visualization which will help you quickly identify root cause of the issue,
How quickly? 1 minute or less ;).
