The Statistics webpage is used for advanced debugging of WI-MOD-E. This webpage details the state of the WI-MOD-E
and performance information. This page is typically useful to WEIDMULLER technical support personnel in diagnosing
problems with the module.
Note that when updating the Statistics webpage, it is necessary to hold down the <ctrl> key while
pressing the refresh button. Otherwise, the information will not be updated.
Wireless Statistics
The “Wireless Statistics” is the main area for further diagnostics statistics.
The list of statistics produced is dynamic and may vary depending on the model and configuration, i.e. 2.4.GHz, 5GHz or
900MHz & Client or Access Point.
Access Point:
Beacon Miss Count:
Number of Beacons unable to be sent (100msec intervals) due to Interference or CCA
Beacon Missed Reset Count:
After 15 Consecutive Beacon misses (1.5seconds) will increment by 1. This will indicate
high interference as AP is holding off sending Beacon and Utilisation will increase.
TX Queue stopped because full:
Message buffer (Ethernet Frames) in radio queue. If Radio cannot transmit due to
high noise, this will increment. When the buffer is full all new messages are dropped. Buffer size 150 messages.
Client:
Beacon Missed Interrupts:
How many beacons (100msec) the Client has missed from the Access Point
TX Failed due to too many retries:
This is how many frames that have been lost. Original M 7 Retries = 1 TX
Failed due to too many retires. Each retry is sent within a few msec.
TX Failed / TX Antenna Profile = Frame Packet Loss Rate (How many undelivered as a %)
RX Failed due to bad CRC:
This can be from any AP not only your own. If other Wi-Fi is around then this number could
be high due to other Encryption keys, weak signal etc.
RX Failed / RX Antenna Profile = RX Frame Error Rate (Note this can be high due to other wireless devices around.)
