The obvious configuration options include whether the Ethernet part of the connection is encrypted (excluding additional devices from being added to the network), and the name, password and encryption applied to the Wi-Fi connection. There aren't any of the more advanced options, such as MAC address filtering, that you would find on a dedicated router, but for an all-in one solution it's comprehensive enough.
90 per cent of users will find that this configuration menu will be visited once and never again - which is a good thing. In our testing we found that the Devolo AV 200 Wireless N adaptors 'just worked' after their initial setup. Our laptops, iPhones and, in fact, ever device we cared to connect, latched onto the Wi-Fi network without a hitch, and plugging devices in using an Ethernet cable was similarly hassle free.
What's particularly good about the combination is that if you somehow decide the few milliseconds of latency added by using Wi-Fi instead of Ethernet are too much for you, you can plug your system in and use a wired connection while it's necessary. We can't see this happening very often, as the major benefit of the Devolo dLan 200 AV Wireless N kit is that it gives you a strong, stable Wi-Fi connection away fro your router. Nonetheless, the option is there.
Alas, you will be paying for the privilege. At almost £100 for the pair of adaptors this Devolo kit isn't cheap. You can pick up a set of non Wi-Fi powerline Ethernet devices for under £30 and add a four-port Wireless N router for under £20. The dLan 200 AV Wireless N adaptors may have the advantage that they take up less space (and fewer socket) but they're still twice the price you're pay if you can sacrifice integration. We're all for elegant solutions, but perhaps not at this price.
The Devolo dLan 200 AV Wireless N adaptor set does work very well, striking a great compromise between the convenience Wi-Fi, and the stability of an Ethernet network. However, you can replicate the system's ability with separate components for something lie half the price, so you're paying a lot for the convenience of the functionality being built in.
