10. Troubleshooting
Probable cause
DTIM might not be set
correctly.
U-APSD is not used.
Cisco/Ekahau location
client settings need to be
changed.
Probable cause
The handset is in range,
but has no access rights.
Handset has found and
associated to the WLAN
(a wireless network with
the configured SSID and
correct security settings).
But it cannot connect to
the gatekeeper or the
IMS3.

Action or comment
1) Check "Beacon interval" and
"DTIM" settings in the AP.
2) Verify the coverage, since low
signal strength will make the
handset to constantly search for
other APs and thereby consuming
more power.
3) Use a sniffer and check the
amount of broadcast traffic that is
transmitted on the WLAN.
4) Check if correct models of the
chargers are used.
5) Verify with another battery.
6) If the system is supposed to use
U-APSD for voice calls check the
voice power save mode parameter
in the PDM.
7) If using Cisco/Ekahau location
client, change the settings.
Action or comment
Switch off the handset and then
switch it on again. If this does not
work, contact the system
administrator.
1) Check if the handset has an IP
address by entering the "Network
info" screen. If not check the WEP
key if used or WPA/WPA2
passphrase.
2) If using WEP, double-check the
key if the handset has no IP address.
If you have a wireless sniffer,
configure it to the correct key and
try to decode packets both from and
to the handset.
3) Check the Gateway address. Try
to ping the gateway from another
PC.
4) Check the IMS3 address. Try to
ping the IMS3 from another PC.
