wifi dongle for RPi model B ver. 2

[homecontroller]

I have been searching the internet for a wifi dongle for an older Raspberry Pi model B ver. 2 with 512 Mb. I think Adafruit has a couple for sale but I am not sure which to purchase. I want this to be as easy an install as possible (e.g. plug and play). My pi was purchased on 4/1/2014. CPU model name is ARMv6-compatable processor rev 7 (v6l). BogoMIPS 2.0, CPU part 0xb76. CPU ver 7. Hardware BCM2708. Revision 000e. The OS is Raspian GNU/Linux 7 (Wheezy) 32 bit. I understand the wifi drivers are included in this version of the OS.

Can you point me to the proper wifi device that Adafruit has for this Pi?

Either of these modules will work. I've had to use a powered USB hub to get optimal WiFi dongle performance.
