Different versions of the wireless tools were used to compile the driver
(kernel space) than to compile the tools (user space), so if there are
big changes in the way the tools expect the drivers to behave, things
will break. 17 to 18 didn't really introduce any big changes that I'm
aware of, just fixes and tweaks, so you don't need to worry.

Are you using WEP/WPA? Unless you configure the interface to be WEP/WPA
aware it won't associate - check google or fedoraforums for howtos. Are
you using MAC filtering on the access point? (If you don't know what
that means, then the answer is probably no ;-) ). Can you actually see
the accesspoint from where you are? What does "iwlist wlan0 scan" show?
