Troubleshooting
PROBLEM CORRECTIVE ACTION
Cannot make (or
maintain) a
cellular data
connection when
cellular signal is
present
(i.e. no Cellular
WAN IP address)
Confirm that the Cellular modem’s APN, Username,
Password, Authentication Type, PIN and ISP Access
Phone Number settings are correct for your carrier.
Confirm that the 3G cellular modem card has been
provisioned with the correct type of Internet access data
service by your carrier.
Confirm that the 3G cellular modem card has been
activated by your carrier and/or by using a Windows PC.
Wrong type of
WAN IP address
is assigned
(i.e. dynamic
instead of static
or private instead
of public)
The IP address assigned to the LAN-Cell’s WAN
interfaces is controlled by your ISP. Confirm that your
account has been provisioned for the proper type of IP
address and that your connection parameters match those
required by your service provider.
For most 3G carriers, the correct setting is
“Get Automatically from ISP” even if your card has a
“static” IP address assigned by the carrier.
Cellular Signal
Strength is low
Check that the proper 3G antenna is securely attached to
the 3G card and/or LAN-Cell’s external 3G antenna jack.
Cellular data connections may be unreliable if the signal
strength/quality is reported as Poor.
Move the LAN-Cell to a location when the carrier’s signal
is stronger or use a higher-gain antenna or amplifier.
Cannot get a
WAN IP address
from the Wired
WAN ISP
The WAN IP address is provided after the ISP verifies the
MAC address, host name or User ID. Confirm the
verification method used by your ISP and configure the
corresponding fields. Try using PAP-only authentication
with no PPP compression.
Check the LAN-Cell’s connection to the wired WAN
(cable/DSL modem). Check whether your Ethernet WAN
connection requires a crossover or straight cable.
Check the settings in the WAN screens, especially the
routing priority and fail-over/load balancing parameters.
