The individual test cards and screens using the Wi-Fi Profile results for the "LRG" SSID are shown below.

Wi-Fi Link Test Results

The Wi-Fi link test card indicates whether you can connect to the configured network at your current location. The Wi-Fi Link card displays the SSID, current signal strength (dBm), link speed (Mbps), and number of roams.

Refer to Wi-Fi Connection Settings if needed.

Tap the card to open the Link test screen.

Wi-Fi Link Test Screen

The Wi-Fi Link test screen shows these results:

SSID
Security: Security protocol in use on the network
Roams: Number of times the unit has disconnected from the previous AP and connected to a different AP with a better signal strength. This behavior is partly controlled by the Roam Threshold in the Wi-Fi Connection settings.

AP: Name, IP, or MAC address of the AP to which the Tester is connected, depending on the information EtherScope can see about the AP. This field shows the custom User Name if one has been entered. See Assigning a Name and Authorization to a Device.

BSSID: BSSID of the access point

Channel: Channel number on which the AP is operating
Roam Scans: (EXG-200 only) Number of times the EtherScope has scanned for a new AP supporting the same SSID. Multiple triggers may cause EtherScope to scan for another AP, such as low signal strength or high retry rate.

Last Roam From: If the EtherScope has roamed to a new AP, the previous AP's name, BSSID, and Channel display.

AP: AP from which the AP last roamed
BSSID: BSSID of the access point
Channel: Channel number on which the AP is operating
Roam Scans: (EXG-200 only) Number of times the EtherScope has scanned for a new AP supporting the same SSID. Multiple triggers may cause EtherScope to scan for another AP, such as low signal strength or high retry rate.

Wi-Fi Link Trending Graphs

EtherScope's trending graphs operate similarly across different testing apps, allowing you to pan and zoom to view different time intervals. Swipe, double tap, and move the slider to adjust the graph views. See the Trending Graphs topic for an overview of the controls.

The Wi-Fi Link Test graphs save and display data for up to 24 hours in the past if the unit stays linked. The default time interval shown is 2 minutes.

Under each graph, a legend table displays the Current, Minimum, Maximum, and Average measurements. The Current column contains measurements from the last second. Min, Max, and Avg columns show cumulative measurements.

Signal (dBm) graph: Plots the signal strength in dBm of the connected AP.

  • Green vertical bars - The tester roamed to a new AP.
  • Red vertical bars - (EXG-200 only) The tester made a roam scan.
  • Signal - The AP's signal strength in dBm.
  • Noise - The noise level in dBm on the channel used.
  • SNR - The network's signal-to-noise ratio in decibels (dB).

Utilization (%) graph: Plots percentage of the connected channel's capacity being used by 802.11 devices and by non-802.11 interference.

  • Green vertical bars - The tester roamed to a new AP.

  • Red vertical bars - (EXG-200 only) The tester made a roam scan.

  • (EXG-200 only) If the Combine Utilization setting is enabled in General Settings, the Utilization graph shows only combined 802.11 and non-802.11 channel utilization. See the General Settings topic for more information.

Retries (% of packets) graph: Plots percentage of transmitted packets that are retry packets

  • Retry Rate % - The percentage of total packets that are retry packets.
  • Retry Pkts - The number of retry packets seen in the current sample cycle.
  • Total Pkts - The total number of packets transmitted in the current sample cycle.

PHY TX Rate (Mbps) graph: Plots the physical transmission rate. The green horizontal dotted line shows the AP's maximum TX rate.

Ping or TCP Connect Response Time graph: This graph displays on the Link test screen if you run a Ping or TCP Connect test, using the Ping/TCP app, over the Wi-Fi test port connection while the Profile is linked.

Follow these steps to view the Response Time graph:

  1. Tap the blue PING hyperlink at the bottom of the Link test screen. This opens the Ping/TCP app with the Interface set to Wi-Fi Port and Protocol set to Ping.

  2. Access and adjust the Ping/TCP settings as desired.

  3. START the Ping or TCP Connect test.

  4. Tap back to go back to the AutoTest Wi-Fi Link screen. The Response Time graph appears near the bottom of the screen and updates in real time along with the other graphs for the duration of the Ping/TCP test.

Result Codes: Final status of the test (Success or Failure)

AP (Access Point) Test

The AP card shows the AP's name and the SSID of the network it is supporting. The AP name or address shown is based on what the EtherScope is able to gather from the device and network. If the AP has a custom user name, that name is shown on the card and test screen.

The AP test is not graded, so the icon remains black.

AP Test Screen

In addition to the AP name and SSID, the AP test screen shows the following:

Device Name: AP's name or address

IP Address: The AP's assigned IP address. If none could be determined, the field displays dashes --.
MAC Address: The AP's MAC address

SSID: Name of the network on which the AP is operating

Security: Security protocol in use on the network
Roams: Number of times the unit has roamed and connected to a different AP
802.11
Channel(s): Channel or channels the AP is operating on. If the BSSID is on multiple channels, the bold channel number indicates the primary channel.
Type: 802.11 type in use on the current link
Supported Types: 802.11 types that the BSSID supports. If none could be determined, the field displays dashes --.

Client Associations: The number of client devices connected to the AP

Roam Scans: (EXG-200 only) Number of times the EtherScope has scanned for a new AP supporting the same SSID. Multiple triggers may cause EtherScope to scan for another AP, such as low signal strength or high retry rate.
