The end devices are
unable to roam from one
access point to another. 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 134.
The end devices are
unable to roam between a
MobileLAN access product
and 011X devices. Set the Unicast Flood Mode to
Hierarchical. For help, see “Configuring
Global Flooding” on page 163.
You cannot originate an IP
tunnel to an access point
on a remote IP subnet. 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.
You need to verify the
static WEP keys. 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.
The filters are not filtering
properly. Check all of your filter settings. Conflicts
may exist between the various filters.
You need to confirm which
master radio a WAP is
connected to. To verify that a WAP is communicating
with a particular radio, view the AP
Connections screen for the access point.
Click Maintenance > AP Connections.
