General Troubleshooting (continued)
Problem/Question
You cannot ping or telnet
to an access point.
The Ping Utility screen
does not appear when you
click a MAC address or an
IP address in the AP
Connections screen.
You cannot connect to the
access point using
MobileLAN manager or
another SNMP
management station.
The end device cannot
connect to the network.
The end device cannot
synch to the access point.
The end devices are unable
to roam from one access
point to another.
The end devices are unable
to roam between a
MobileLAN access product
and 011X devices.
You cannot originate an IP
tunnel to an access point
on a remote IP subnet.
Possible Solution/Answer
1. You must set an IP address and subnet mask using the
MobileLAN access Utility or a communications
program before you can remotely connect to the access
point.
2. Verify that you did not disable the Telnet Access field
in the Security screen.
3. The access point may have lost its files. For help, see
"Recovering a Failed Access Point" on page 207.
The web browser you are using does not have Java
support. Intermec recommends that you use Internet
Explorer v3.0 (or later) or Netscape Communicator v4.0
(or later).
Verify that you did not disable the SNMP Access field in
the Security screen.
•
In the Maintenance menu, choose AP Connections
and verify that the MAC address of your end device
appears on your PC screen. If it does not appear, your
end device is not communicating with the access point.
Check your radio configuration settings.
•
Verify that the access point is not filtering out the type
of traffic you are trying to pass through it.
Verify that the end device and the access point have the
same SSID (network name) and security.
The switches in your network may not support backward
learning. Use data link tunneling to force all wireless traffic
through a fixed point so that roaming is transparent to the
bridges or switches.
The end devices must have IP addresses from the root IP
subnet.
For help, see "About Ethernet Bridging/Data Link
Tunneling" on page 103.
Set the Unicast Flood Mode to Hierarchical. For help, see
"Configuring Global Flooding" on page 127.
1. Verify that the IP Router (Gateway) address is correct.
2. Verify that the access points on the ends of the tunnel
have the same LAN ID.
3. On the root access point verify that the IP address of
the access point at the endpoint of the IP tunnel
appears in the IP Addresses list.
