Troubleshooting Client Connectivity from the Wireless Access Point

There may be cases where multiple users are having issues with the same general area or access point.

The split-MAC architecture in Cisco wireless provides a few points where troubleshooting can occur.

For a lightweight access point to operate, it needs to have connectivity through its access layer switch, and connectivity to the wireless LAN controller (Unless the access point operates in FlexConnect mode)

The connectivity between the access point and the controller should be verified as a first step. The access point should be able to discover and join a wireless LAN controller.

Access points that have joined a wireless LAN controller are in a list of live access points in the wireless LAN controllers management GUI. This can be checked to ensure the access point has got a method of communication to the wireless LAN controller.

Similar to a client view, the wireless LAN controller has a view for statistics and information about each access point connected to the system.

The access point information can show it’s connection to the network, it’s IP address and show CDP information if available on what device it is directly attached too.

The performance summary shows information on the wireless performance and radio frequency conditions.

It gives statistics on the utilisation of the radio channels and how busy they are in percentages. A highly utilised channel will mean less air time for clients to send or receive traffic across the wireless network.

The air quality is shown which indicates how competing and interfering devices compromise the airtime quality or performance on a channel. It is presented as a number as 0 for worst and 100 for the best quality.
