Richard, I do apologize for my mistake. I found that the rtl8192cu can't send the beacon frame at mesh mode. Sender side wireshark shows sending beacon frame. but receiver side wireshark doesn't show the rtl8192cu's mesh beacon. I think connection issue's cause is rtl8192cu's wrong beacon code. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
