Appendix B. Troubleshooting
This section provides information about how to solve common problems you might
encounter in the course of updating network configurations on networks served by
multiple, clustered access points.
Cluster Recovery
In cases where the access points in a cluster become out of sync or an access point
cannot join or be removed from a cluster, the following methods for cluster recovery
are recommended.
Reboot or Reset Access Point
These recovery methods are given in the order you should try them. In all but the last
case (stop clustering), you only need to reset or reboot the particular access point whose
configuration is out of sync with other cluster members or cannot remove/join cluster.
• Reboot the access point from its Administration UI. To do this, go to http://
IPAddressOfAccessPoint, navigate to Advanced > Reboot and click the Reboot button.
(IP addresses for APs are on the Cluster > Access Points page for cluster members.)
• Physically reboot the access point by pressing the Power button on the device.
• Reset the access point from its Administration UI. To do this, go to http://
IPAddressOfAccessPoint, navigate to Advanced > Reset, and click the Reset
button. (IP addresses for APs are on the Cluster > Access Points page for any cluster
member.)
• Physically reset the access point by pressing the Reset button on the device.
• In some extreme cases, reboot or reset may not solve the problem. In these cases,
follow the procedure described next in "Stop Clustering and Reset Each Access Point
in the Cluster" to recover every access point on the subnet.
Stop Clustering and Reset Each Access Point in the Cluster
If the previous reboot or reset methods do not solve the problem, do the following to
stop clustering and reset all APs.
1. Stop clustering on each access point in the cluster.
To do this, enter the Stop Clustering URL in the address bar of your Web browser as
follows:
http://IPAddressOfAccessPoint/stop_clustering.cgi
Where IPAddressOfAccessPoint is the IP address of the access point you want
to stop clustering.You can find the IP addresses for the cluster members on the Cluster
> Access Points page for any of the clustered access points. We recommend making
a note of all IP addresses at this point.
