9400 supports WPA2 if you are using latest firmware and latest PEPV2 editor vs the Pronto Configurator that came on the CD with the remote. All the stuff you need can be found on the Philips site or in Files Section here. In fact, there's a thread discussing latest firmware and editor on page 1 or page 2 of this forum as I write this.
