DM800HDpro compatible wifi dongles

Hello everyone
Just wondering if someone can help me with this question,
I have the latest DM800HD+ (clone) Receiver, and need Wi-Fi connection,
I found this awsome mini Edimax EW-7811UN Wifi dongle online.
Before i buy this dongle, can anybody tell me please if this is compatible with DM800HD+ or so called (pro)?
The thing is i want to install in internal USB port
Thank you

I forgot to say the motherboard on this DM800HD box is KMAX S8000 V1.0, Bootloader 76, sim 2.1, Gemini 5.1, Tuner is Version M
