No PC configuration is required. Fortunately I do not own a Windows PC.
On Android and Linux you can browse to the IP address of the MBL to conifugure it.
In linux, you need to install SAMBA, and then the MBL appears in the file manager as a network share.
In android you need to install one of the many file managers. I use “ES File Explorer”. You select to view “Lan” rather than “Local”, and the MBL will appear. WD2GO for android is just bloatware, and not worth installing - use ES File Explorer instead. The Twonky Android app is however good for your streaming music.
With Chrome OS you just install a SAMBA app, and you will be able to view the MBL.
It doesn’t matter if Linux has 0.0000001% of the market share. The MBL firmware has been written in Linux, so WD have linux developers, so there is no reason why WD cannot support Linux. Google “MBL hack” and you will find how you can connect to the linux computer within the MBL.
