Sorry for the long silence on this, I was busy with some other things.
But I've been playing with it again this week and uncovered some new
information regarding the failures.

I noticed the other day that the rtl8188ce was no longer having trouble
associating with this AP. After playing around in the router settings I
discovered that it works fine so long as the router isn't on channel 1.
So then I configured my other router to use channel 1, and then I
started seeing problems with that router as well.

I also tried the rtl8192ce driver from Realtek's website, and I'm having
better luck with that driver.
