Settings for WDS with 5 AP's

I have 5 AP’s setup in WDS but am wondering if I have it setup right. I am using STP but seem to have slow intranet connect. I get long delays connecting to intranet sites and assets. I am wondering if I have some loops etc going on. Can someone tell me how I am supposed to have the AP’s connecting to each other? Should I have the one AP connected to the lan via ethernet connect to each of the other AP’s only or should each AP be able to connect to any other AP? The signal from the main AP to all others is very good. Is there something I should do to keep them from connecting to each other and only connect to the main AP?

Thanks

Can use the ACL to do that… maybe use RSTP bridge…
