You cannot connect to the access point using an SNMP
management station.
Verify that you did not disable the SNMP Access field in the Security
screen.
The end device cannot connect to the network.
❑ Choose AP Connections from the Maintenance menu and verify
that the MAC address of your end device appears on your PC
screen. If it does not appear, your 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.
The end device cannot synch to the access point.
If you are using 802.11b HR radios, verify that the end device and the
access point have the same frequency and network name.
The end devices are unable to roam to another AT-WL2411.
Roaming through switches requires backward learning, which is part of
the IEEE 802.1D standard. If switches in your network do not support
backward learning, you can create a data link tunnel to force all radio
traffic through a fixed point so that roaming is transparent to the bridges
or switches.
To create a data link tunnel, perform the following procedure:
1. Set Ethernet Bridging to Enable on the root access point.
2. Set Ethernet Bridging to Disabled on all access points that are
separated from the root by a bridge or switch that does not support
backward learning.
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.
