MobileLAN access 21XX System Manual
General Troubleshooting (continued)
Problem/Question
The end devices are unable to
roam between 21XX and 011X
devices.
You cannot originate an IP
tunnel to an access point on a
remote subnet.
You need to verify the static
WEP keys.
The filters are not filtering
properly.
You need to confirm which
master radio a WAP is
connected to.
The throughput seems slow.
7-16
Possible Solution/Answer
Set the Unicast Flood Mode to Hierarchical. For more
information, see "Configuring Global Flooding" in
Chapter 4.
1. Click TCP/IP Settings and verify that the IP Router
(Gateway) address is correct.
2. Click Spanning Tree Settings and 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
remote access point appears in the IP Addresses list.
You cannot verify the WEP keys. The keys are encrypted
after you enter them and are never displayed again. You may
need to reconfigure your access points and end devices to
reset the WEP keys.
Check all of your filter settings. Conflicts may exist between
the various filters.
To verify that a WAP is communicating with a particular
radio, view the AP Connections screen for the access point.
Click Maintenance and then click AP Connections.
•
Verify that your antennas are well placed and that they
are not blocked by metal or other obstacles.
•
You may want to add a second access point and
implement roaming if you move the antenna closer to
the device and throughput increases.
You may be able to set filters to eliminate Ethernet traffic on
the wireless side of the network. For more information about
filters, see Chapter 4, "Configuring the Spanning Tree."
