... Makes this adapter to a very good dLAN supplement. The first step after plugging into the wall outlet is the integration into the network using devolo devolo cockpit. After that you should bring the firmware up to date (you can leave the TL-WPA4220 it in the socket!). When the update is done, the TL-WPA4220 must be again involved with devolo cockpit into the network. Then it comes to the configuration of the wireless network. ! The WPS function between FRITZ! Box and TL-WPA4220 has not worked, but (accessible from the scanning tool on the supplied CD: Press the "Connect") to enter the wireless data on the TL-WPA4220 menu works very easy (entering the wireless SSID broadcast channel, encryption, wireless key). If you change the socket receives the TL-WPA4220 a new IP address. If you want a fixed IP, you can forgive them and save them in the TL-WPA4220 menu.
