My Fritzbox 7390 I have not bought from Amazon, but would like to tell here in spite of all my experiences. On the Internet you read of various problems which the box. Despite all this, I ordered it. During installation, there was, as you'd expect from AVM, no problems. But then in operation, the read problems began. How zBDECT poor reception and Wi-Fi sporadic crashes. Since I was a little disappointed. But then I have been playing the laboratory firmware, after rebooting it still came to the problems described above. so I pulled the plug of the Fritz box and discharged more than a minute. After this reboot, I have had no problems with the box so far. It runs like clockwork. I stay true to AVM, already because of the good support. With me now run 4 AVM products and all without problems. For the Fritz box 7390 the new firmware update has been announced where the experience of the laboratory firmware will feed with AVM now. Then there can be for no more problems. So, do not give up immediately, special once play the last laboratory-firmware. Then make the box for a minute and restart normally. Go for the DECT problem in the DECT Settings and uncheck "DECT transmission power devalue" take out. Then it is determined fold.
