Hi. I'm having the same issue setting up my WIFI dongle on my vu+ zero box running Black hole 3.0.1.
Not sure if I'm missing a step here, but when I go to Menu-Setup-System, there is no option for Wireless LAN setup.
I have my wifi dongle plugged in, however this dongle was taken from my old F5 skybox, and has skybox written on it. I'm therefore unsure if this compatible with my vu+ zero, and if this is why the menu option is not visible.
I've tried adding the driver using the 'rt3070_2.5.0.3-r4-bh0_bm750.ipk', however still no menu option. Unsure if I perhaps need some sort of WIFI plug-in, or if I need a new WIFI dongle.
Any guidance would be much appreciated!
