There are not any b43 errors in dmesg and considering your scenario I
don't think driver has anything to do with this.

I don't understand your part: "it asks for the AP credentials". What
do you mean by "it"? AFAIK wpa_supplicant does not have interactive
mode.

The situation sounds pretty simple. Your connection was broken (that
happens in WiFI, with every card/driver) and SOMETHING tries to
connect to another AP you configured...
