Troubleshooting
PROBLEM CORRECTIVE ACTION
Wi-Fi clients
periodically
disconnect, esp.
when LAN-Cell
configuration
parameters are
updated
Some updates to the LAN-Cell’s configuration require that
the Wi-Fi Access Point be reinitialized, causing client
connections to drop. Configure Wi-Fi clients to
automatically reconnect to the LAN-Cell.
Upgrade the firmware and driver software on your Wi-Fi
client devices to the latest version.
After pressing
RESET, cannot
make a cellular
connection
The RESET button returns the LAN-Cell to its factory
default settings including clearing any cellular modem
parameters. You must reconfigure the necessary 3G
connection parameters.
Common Carrier-Specific Issues
CARRIER COMMENT
Alltel By default, Alltel blocks all packets originating from the
Internet. Contact Alltel technical support to unblock the
necessary ports for your application.
Alltel’s default gateways do not respond to ICMP (ping)
packets. Do not select the “Ping Default Gateway” option
under Cellular Connectivity Check; select another public IP
address or DNS name.
AT&T Mobility The APN “isp.cingular” blocks all packets originating from
the Internet. If you must access the LAN-Cell or other
equipment remotely, request that AT&T give you access to
the “internet” APN (mobile terminated data service).
Sprint PCS Sprint blocks access to ports 80 & 5000 (and perhaps
others) from Internet addresses. Move your servers to a
different port number or use the LAN-Cell’s NAT Port
Forwarding & Redirection feature to map to open ports.
Verizon Wireless Verizon Wireless’ default gateways do not respond to ICMP
(ping) packets. Do not select the “Ping Default Gateway”
option under Cellular Connectivity Check; select another
public IP address or DNS name.
