God Eater Burst

[Jay0161]

I've seen videos online showcasing God Eater Burst online gameplay via PPSSPP (PC). So I am aware that the game works online, but what about Ad-Hoc using the same internet?
I attempted to play online with my brother (In the same house, using the same internet) but it didn't seem to work. It won't let us even go online at the same time. Anytime we both try to go online, it only works for one of us but the other gets stuck on this screen    
At first I thought it was just a coincidence. So we kept trying, in hopes it would finally get us both on, but it was the same thing over and over again. It would only successfully connect     for whoever goes on it first, but whoever tries to it second, gets stuck on the connecting screen.

It probably has something to do with us using the same internet.
Has anyone else here tried and experienced the same thing or is it just me?
