This piece of hardware is giving me headaches everyday.

I'm trying to connect with GCC on my desktop, because it's easier for me than on my iPhone.

I've tried everything,
with specific IP and port, automatically, other port, etc.
In GHL connect i've set wifi to B, B/G and B/G/N
I've tried with my desktop connected to lan, connected to wlan and connected to both

I just can't connect with GCC on my desktop nor on my iPhone
I can ping it, find it with IPscanner, got to the IP in my webbrowser, find it in the connected devices in my modem, i can connect to it with my iPhone with GHL connect,...

Can someone please help me with this?
