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.

Wireless Distribution System (WDS) Problems and
Solutions
If you are having trouble configuring a WDS link, be sure you have read the notes and cautions in
“Configuring WDS Settings”. These notes are reprinted here for your convenience. The most common
problem Administrators encounter with WDS setups is forgetting to set both access points in the link to
the same radio channel and IEEE 802.11 mode. That prerequisite, as well as others, is listed in the notes
below.
Note: When using WDS, be sure to configure WDS settings on both access points
participating in the WDS link.
You can have only one WDS link between any pair of access points. That is, a remote
MAC address may appear only once on the WDS page for a particular access point.
Both access points participating in a WDS link must be on the same Radio channel and
using the same IEEE 802.11 mode. (See “Configuring Radio Settings
” for information
on configuring the Radio mode and channel.) For more information on IEEE 802.11h,
see “802.11h Regulatory Domain Control
”.
Any two access points can be connected by only a single path; either a WDS bridge
(wireless) or an Ethernet connection (wired), but not both.
Do not create "backup" links.
If you can trace more than one path between any pair of APs going through any
combination of Ethernet or WDS links, you have a loop.
You can only extend or bridge either the Internal or Guest network but not both.
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.
Physically reboot the access point by pressing the Power button on the device.
