Hello Futeko,
I bought this media player
years ago and I never managed to stream through wifi.
I bought it for its wifi ability but after years i still move movies through usb

I connected it with my Wlan through settings, I also set the network group, I press to enter file mode and it ask me
login network name and passwhatever i set in these boxes it tells me
Login Error (windows login and pass, router pass, network name group all nothing)
I have opened everything i could found on windows and on the router, services, ports, closed firewalls etc
I used all versions, currently 1.0.5.7
ANY ANY, help or advice would be acceptable and would be thankful (you free to use also teamviewer)
