I don't know but I believe, this is your real problem. You have to
find out what deamon manages your connections without you begin aware
of that.

I already asked you important question but your answer was something
totally else than what I expected. I asked *WHAT* is asking you for
"AP credentials" and you responded with "computer looses connection to
my AP and connects to another one". Well, just check what application
is asking you for "AP credentials" and kill it.
