Suggestion on Wireless network configuration

Hi
I have server 2003 ent edition.  Right now I have around four 3com 8760 dual radio 11a/b/g wireless nodes, which does the job of connecting wireless laptops in our domain to the network.  The simple configuration right now is as follows:
-Each wireless node is installed at different locations of the bulding.
-Each wireless node is on a different radio channel.
-Each wireless node is able to provide IP addresses (taken from DHCP server) to the wireless laptops (i.e each wirless node is independent)
-Each wireless node has WDS settings which has options, Bridge Role as AP, Bridge, Repeater, Root bridge.  All nodes are at AP (selection).
-Spanning Tree protocol setting is Disabled on all the wireless nodes (Not sure if enabling it will make any difference)
-Using WPA/PSK as the authentication method in Each wireless node.

The problem:
WHen a user switches locations (i.e from one location of a wireless node to another location of wireless node)  the re connection of the new wireless node and the laptop takes longer time???

-Should these wireless nodes be some sort of bridged?
-Should one wireless node be acting as independent node and the rest should act as repeaters?

It is always best to have your APs hard wired to your network. Bridging can slow your communication and add latency.

Because of security, and the changing of channels as a user progresses through your building, the time to lock on and connect takes some time almost as long as an original connect.

You "can" make all the channels the same, but some issues may arise. This might quicken the connection. It is easy to experiement as generally, and unless you have users online, they won't know it.

You might want to read the answers to the following Q here on EE where I did some pretty good experimentation with channels, all the same and then different.

Your channels should also be 5 channels apart and make sure there isn't other RF interference from other APs in the area. Google NetStumbler and load it on a wireless laptop to see what else may be around.

In summary, your config looks great to me!
