I got a new router from my ISP (Tilgin HG2381), normaly i have a Tilgin 1351 and it work perfectly, but know:
It can find my Nas
It can find my folders and whats in them
BUT Infuse Pro can only play about 3 sec, then it freeze.
No problem with VLC, except the AC3 sound
I switch back to the old Tilgin, no problem
I have reset all the settings, nothing helped.
