The device has a WPS button, which is not described. Actually, the connection should therefore fold quickly and easily, the FRITZ! Box 7390 is the process, but it is nowhere described in the TechniSat instruction (short press or long or multiple, no idea). I've also experienced with other devices in the FRITZ! Box. Sometimes it works then, sometimes you do not. Difficult to judge what it is, because the integration into the network can last several minutes and all connection attempts are pointless at this time.
The hakelige integration into the grid and the little helpful guide costs nerves. For a description of how to build an example with the wireless adapter on the receiver to connect to the one or two most popular wireless routers, would be very helpful. Above all, a little checklist, are listed in the error possibilities, solutions and advice.
Otherwise, I am now satisfied. Access to the Media Server and the Internet works without problems.
