I think he’s trying to connect his RPi2 to the Mango - it doesn’t have onboard WiFi…
TP-Link TL-WN725N is RTL8188EUS - same with V2 of that device, and there’s no built-in kernel support with the r8818eu driver
The Edimax device - similar - based on RTL8188CUS, which again, no kernel support in Raspbian
The CanaKit purpose built adapter should work - it’s Ralink 5370 based, and it’s $10USD on Amazon
