5. Check whether the problem occurs only with the selected RLM, or with
multiple Access Points RLMs.
• If the problem is observed on only one Access Point RLM, the
problem may lie in the connectors or cable(s) that connect the Radio
Link Module to the hub or wired backbone.
• When the problem exists with multiple Access Points RLMs, it is
likely to be caused by the cables or connectors of the wired
backbone, hub or the bridge/router device that connects this
network segment to your LAN.

Using the procedure described above, you may have determined the area
where a cabling error might be suspected. To resolve the problem, carefully
check the cabling system in this area to verify whether all connectors are
properly seated at the:
• Access Points RLMs
• Bridges, routers and hubs
• Wired stations connected to the cabling system.
If your network uses BNC coax cable (10Base2), make sure that terminators
are placed on both ends.
