We have a Black Genius (Full not light), the LAN cant seem to see the WLAN (WiFi).

Generally we use WiFi for all of our devices and they can happily see each other (tablets, phones, printers, PC's etc).

Ive now got a device that needs to use the LAN on the Genius. If I plug the device in I get internet no problem but I cant ping any of the other devices on that are connected via WiFi.

 

I haven't changed any settings on the Genius as far as I know.

Anybody have any ideas why the WLAN cant see the LAN network?

Thanks
