I decided to remove the card from the netbook and test it in another
machine, and it worked flawlessly. A different card in the netbook works
fine as well.

But then after reinstalling the rtl8188ce in the netbook I'm not seeing
any problems associating. None at all. So perhaps the issue was
mechanical in nature.

I'll keep testing it for a while to see if the problems resurface, but
for now everything seems fine. Thanks for your help.
