Wireless Distribution System (WDS) Problems And Solutions
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.

D.1 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” on page 203. 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.

Notes: •
When using WDS, be sure to configure WDS settings on both access
points participating in the WDS link.
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 “Configur-
ing Radio Settings” on page 165 for information on configuring the
Radio mode and channel.) For more information on IEEE 802.11h, see

Ensure Spanning Tree Protocol (STP) is enabled to prevent endless loops
and path redundancy with either WDS bridges or combinations of Wired
(Ethernet) connections and WDS bridges. If STP is enabled, you can use
WDS to create backup links. If STP is disabled, keep these rules in mind:

(Ethernet) connections and WDS bridges. If STP is enabled, you can use
WDS to create backup links. If STP is disabled, keep these rules in mind:
- 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
- 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.
