The devices are compatible with all other devolo products from dLan 200 AV onwards. So they are also compatible with wireless devolo devices. I use the AirPort Express from Apple for wireless, which is then simply connected to one of the two Ethernet outputs.
devolo wireless has powerline and wireless in one device:. If you drive a Mac (like me), you're oriented towards Apple products, but devolo does the same thing. (Besides, with Airport I can still feed my music into any stereo system. I don't know if that would also work with devolo).
Thank you for the answer. That's great. As I understand it, you use Powerline and AirPort Express together? What is the difference between devolo wireless and AirPort Express except that Airport Express is more flexible in terms of location and devices?
