WD MyBookLive disappeared

Hi,
I recently had to change my router. Having done this, I reconnected everything up. The router is remote from desk, so an ethernet cable from it arrives to a gigabit switch, into which laptop, WD MyBookLive, one Sonos speaker are all connected. Since then, MyBookLive has vanished. It does not even show up as a storage device. The ethernet link LED is lit, and the ethernet activity LED flashes as though it is connected. I can hear the disk working. The front LED is out, but it often used to be, to no detriment to its operation. All my iTunes library is on the NAS drive, so I really want it back, as that is where my Sonos system goes for music! Any ideas appreciated. WD discover can’t find it. Running Windows 10.
