Hi, The new Enspire pianos come with a USB/Wifi device (UD-WL1) for wireless
internet/PC access. In working with the good folks in support this can
be problematic compared to directly wiring the Enspire to a switch or
better yet directly to a home router (which is what I do and it works
flawlessly).
With my new Enspire the UD-WL1 often dropped out and this may have been due to how
much electromagnetic energy that is produced around the drive and
component boxes stored under the piano. There's even warning in the Enspire documentation which points out that the Disklavier components can interfere with other electronics, depending on proximity. So a direct Ethernet cable to a WiFi extender, router, hub, or switch placed some distance from the piano will probably nib this in the bud.
