Hmm, you probably need to distinguish what your real problem is, and
what you think
the problem is. I have a few
"wlan2: beacon loss from AP <mac_address> - sending probe request" in
my dmesg since I upgraded
lately, but my wireless connectivity is fine. I think that message is
just the occasional informative/debug messages
that the kernel dev people add, just to be informative (and I am using
a different driver/hardware altogether).
