Key Task: Analyze WiFi

Use Analyze WiFi to correlate between WiFi performance and other attributes like location, device manufacturer, department.

For example, if some users have slow performance in a location, and you suspect it might be due to poor WiFi, you can check if those people all use the same WiFi hotspot, by showing the breakdown of usernames and their SSID (or specific transmitter with its BSSID), and then determine if the problem is due to low signal strength, slow speeds, or poor SNR (signal quality drowned by background noise).

You can also see an hourly summary of this data via the REST API called WIFI_STATISTICS_HOURLY. Learn more.

Procedure

  1. Step 1 Open a browser and sign in to Aternity.
  2. Step 2 Select Main Menu > Analyze > WiFi.
    Select Analyze WiFi dashboard
  3. Step 3 Select the measurements you want to examine as columns in this dashboard in the Measurements menu on the right side.
    Select the measurements to display as columns
    Field Description
    Hours on WiFi

    Displays the number of hours when this device remained connected to this WiFi BSSID.

    Noise Level (Average) / Noise Level (Maximum) / Noise Level (Minimum)

    (Macs only) Displays the background noise level of the WiFi connection for this device, measured in decibels. High noise levels lower the quality of a connection (signal to noise ratio), which slows the effective speed of that connection, which in turn lowers an application's performance.

    SNR (Average) / SNR (Maximum) / SNR (Mininum)

    (Macs only) Displays the WiFi signal-to-noise ratio (SNR), which is the strength of the data measured in decibels minus the background noise. Low SNR impacts significantly on network performance. Higher speed connections require a higher SNR. For example, at 54 Mbps you need an SNR of at least 25 decibels.

    Signal Strength (Average) / Signal Strength (Maximum) / Signal Strength (Minimum) /

    (Windows Agent 9.2 or later, Macs and mobile devices) Displays the percent strength of the WiFi signal which the device receives, which can impact communication speed. For more details, hover your mouse over the graph in the dashboard to see the name of the WiFi network connection (SSID), the wireless network card MAC address (BSSID), and the WiFi channel.

    Transmission Speed (Average) / Transmission Speed (Maximum) / Transmission Speed (Minimum)

    (Macs and in Windows from Agent 9.2) Displays the potential speed (bandwidth) of the WiFi connection at that moment, in megabits per second (Mbps). Lower WiFi bandwidth can be due to poor signal strength or overlapping channels, which slows the network time. In Windows, see the potential speed in the Control Panel > Network and Sharing > Adapter Settings > Status of the WiFi connection. In Macs, view it in About This Mac > System Report > Network > Wi-Fi.

  4. Step 4 Focus your dashboard using Breakdowns and Filters, to assess whether you are on the right track to understand the cause of the issue.
    1. a Select the two criteria (Breakdowns) that you want to correlate, using the panel on the right hand side.

      When you choose two Breakdowns, Aternity displays them as the two leftmost columns of the dashboard.

    2. b Choose Filters and Filter Values to limit the display to the data where the attribute has that value.

    For example, to view the users on a specific hotspot and their performance metrics, select First > Usernames and Second > WiFi SSID.

    Choose the two criteria (Breakdowns) to check for correlations and narrow further with filters

    Select any of the following fields to appear as Breakdowns or Filters.

    Field Description
    Business Locations

    Displays the name of the current location of the device. This is different from the Office, which is fixed for each user.

    For example, if a user based in the Houston office is working from the Chicago office, the Office is Houston, while the Business Location is Chicago.

    Day of Week

    Select to filter the displayed data for one or more days in the week.

    Departments

    Check if the drop in performance is centered around a specific department, which can point to a configuration which is unique to that group of users, by viewing the performance in the list of departments. For example, if you find that only the Sales department is suffering poor performance, you can trace it to an upgrade which only happened on their computers, like a new CTI which interferes with your application.
