Larry, thank you for reply.

I set up my router with WPA2 //  the USB ID Device 008: ID 0bda:8187 Realtek
Semiconductor Corp. RTL8187 Wireless Adapter.
(I used lsusb in my 3.8.2, I hope it makes no difference, it's the vendor device
id I suppose...)

I generated a 64-bit version of Linus's current mainline tree. The results for carious commands are as follows:

As you can see, my system connected to a WPA2-encrypted network running 3.9-rc1 from the mainline tree. I do not know what problem you are having, but I cannot reproduce it. My USB ID is different, but the chip is the same.
