Ethernet port from the Summary Status window of the AP browser interface. When you investigate problems
with the connection of an AP to a wired LAN, be sure that the AP is configured with the proper mode, either
root or repeater.
An AP that is configured as a root device has these characteristics:
Accepts association and communicates only with clients and repeaters
• 
Does not communicate with other root devices
• 
Can be one of many root devices per RF system
• 
An AP that is configured as a nonroot or repeater device has these characteristics:
Associates and communicates to a root or another nonroot that is associated to a root
• 
Accepts association and communicates only with clients and repeaters, if the AP is registered to a root
• 
In the current software versions, the APs configured in Bridge mode also can associate wireless clients. But
for normal wireless connectivity, the AP must be configured in Root mode. For more information refer to the
Configuring Radio Settings section of Cisco IOS Software Configuration Guide .
Device Configuration
Make sure the switch port to which the AP is connected is configured appropriately. If multiple VLANs are
configured on the AP, configure the switch port as a Trunk port. If all the wireless clients belong to the same
VLAN, you can configure the switch port as an Access port. Ensure that the wireless VLANs are allowed on
the trunk ports or else the traffic for the VLAN will be not be allowed through the switch. For more
information on how to configure the switch, refer to Using VLANs with Cisco Aironet Wireless Equipment.
Port Consideration
Try to match the speed and duplex capabilities as closely as possible. Hard−set values for speed and duplex
tend to work better than autonegotiated ones. Give equal attention to the port to which the AP is connected
and to the AP Ethernet port. When you hard set the AP to a particular speed and duplex value, hard set the
port on the switch or hub to which the AP connects as well. Be cautious when you use unmanageable devices
like 10/100−Mbps autosensing hubs. Problems can occur when you mix these two rates in the same hub. The
Statistical Analysis section of this document describes conditions in which the port on the hub or switch can
be suspect. A change of ports or swap out of the hubs, switches, or cables can be necessary in an effort to
isolate the problem.
Physical Connectivity
Physical connectivity is often the point at which to start. Be sure that an AP is connected to a hub or switch
with a straight−through cable. If the AP is plugged in to an uplink port or connected directly to an end PC, a
cross−over cable is necessary. Use a cable that is at least 1 meter (m) (about 3 feet [ft]) in length. Do not
exceed the Ethernet cable−length recommendations in this table:
Cable Type
Length
Coax 10BASE−2
185 m/607 ft
Category 5 10BASE−T
100 m/328 ft
