Which Xbox One controller exactly?
So you have installed Batocera on the internal SSD and for Roms you are using a USB SATA Drive?
By the way... there is no stable 5.25 version yet. Are you using the current beta version (5.25-dev 2020/02/14 01:03, file-name: batocera-5.25-x86_64-20200216) or an older beta version of 5.25?
Did you try to remap the buttons within ES Menu? (Controller Settings, Configure a Controller)
And could you describe your network issue a bit more? I did not understand
