Hi Larry and everyone else on the list, I've seen your 25 patches and applied them in hope my problems were resolved. They are not :'( I've tried to look further, I think that the root of this problem is in core.c, in the rtl_op_bss_info_changed function. This function make a call to get_sta on the new bssid. The problem is that at this point, the sta is still not inserted, thus cannot be accessed by this method. As far as I understand the code, this specific rtl_op_bss_info_changed is responsible for setting rtlmac->mode, which explains why this mode is never set on my system.
