Wireless Distribution System (WDS) Problems And Solutions

This section provides information about how to solve common problems you might encoun-

ter in the course of updating network configurations on networks served by multiple,

clustered access points.

C.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 cau-

tions in “Configuring WDS Settings” on page 206. These notes are reprinted here for your

convenience. The most common problem Administrators encounter with WDS setups is for-

getting 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 partici-

pating 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” on

page 169 for information on configuring the Radio mode and channel.) For more

information on IEEE 802.11h, see “802.11h Regulatory Domain Control” on

page 148.

Ensure Spanning Tree Protocol (STP) is enabled to prevent endless loops and path

redundancy with either WDS bridges or combinations of Wired (Ethernet) connec-

tions 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 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.
