Troubleshooting Scenarios
Check the Regulatory Domain and Selected Channels
The wireless spectrum regulatory domain defines which region's rules the handset should comply to. Based
on the handset version (see
regulatory domain:
• Cellular version – No action needed (cellular network is used even when no SIM is inserted).
• Wi-Fi version in US – Set FCC (for information on how to change domain settings, read below).
• Wi-Fi version in rest of the world – No action needed (802.11d is set as default).
If the World mode is set, the handset listens for a beacon containing 802.11d formatted region
information, before transmitting anything (this requires support and configuration from the
infrastructure).
If roaming between an indoor and outdoor area is a requirement, 802.11d (World mode) cannot be
used to determine regulatory domain. In these cases it is important to instead specify the
regulatory domain the handset is operating in. Such as ETSI (Europe), Japan, etc.
The handset gets its regulatory settings from the AP. If this is not supported by the AP it has to be
configured for the handset as follows:
1. Go to the Settings > Ascom settings > Wi-Fi > Define option for regulatory domain
2. Select one of the following settings:
− World mode (default)
− FCC
− ETSI
The enabled on the handset channels should comply with the corresponding regulatory domain. If not, do
the following:
1. Go to the Settings > Ascom settings > Wi-Fi > Select channels
2. Choose the channels to be used.
Check Time and Date
If the time or date on the handset differs from the current time or date, the certificate, for example SSL, TSL,
or Wi-Fi, might consider the connection invalid. This is the most common in cases when the certificate
expires earlier than the time or date set on the handset.
The date parameter is the most important as minor differences in time do not influence much.
To change time and date on the handset, do the following:
1. On the handset, go into Settings > System > Data & time.
2. If Network- or GPS- provided time is selected in Automatic date & time window, change it for Off and
set time or date manually.
3. Restart the handset.
