check the connectivity bt disabling stp or rstp. I do not believe the issue is related to the Catalyst switches in his environment but the Wireless bridges. BR1310 should forward BPDU when STP is disabled on the devices. However, there's an outstanding Bug
CSCed94862 please see the bug - bridge does not forward SSTP message when STP is disabled.
Here is a link that will help explain RSTP.
