Troubleshooting WLAN IP Telephony installations

Diagnostics Mode

Diagnostics Mode evaluates the overall quality of the link between the handsets, AP, and the
infrastructure equipment (call server, WLAN IP Telephony Manager 2245, and gateways).
Diagnostics Mode can be used when the handset is active.
When Diagnostics Mode is activated in the Admin menu, the handset enters the diagnostic
state. The handset can display diagnostics any time it is on a call.
Pressing the Menu key displays a number of diagnostic counters. Five screens of counters
can be displayed by pressing the Menu key to scroll through the following screens:
• Screen 1—displays counters for missed receive packets, missed transmit packets,
receive retry count, and transmit retry count.
• Screen 2—displays jitter delta, last successful transmit data rate, and gateway type.
• Screen 3—displays a list of APs and some of their details.
• Screen 4—displays association and reassociation counts.
• Screen 5—displays security error count and sequence number for last security error.
After all the counters are displayed, the screen returns to the normal off-hook display.
The screen number appears on the top line of the screen.
Diagnostics Screen 1 displays the following information:
