Hi Surendra,
I set static IP on interface BVI1 on non-root1 and non-root2, also root-bridge I can ping to both of them, in fact I access  to them via web and telnet.
I also set ip helper-address on interface Dot11Radio0 in all APs root and non-root..
My mind is about to crash...I don´t know what else to try.
thanks for your time.
