Better than 7390 but ... Data from 7390 can be taken only conditionally

Here I do not want to repeat what has already been written increased.
I have the Fritz box 7490 brought me as a successor to the 7390. According to AVM, it is easily possible to take all the data from a backup of 7390. THIS IS WRONG !!!
While efforts are being taken over almost all of the data but you have to eg VPN, MyFRITZ, DECT, smart home to redecorate completely.
In my case, almost all wireless cameras had to be set up, since this memorize the MAC address and this change is well known.
I've spent so almost 5 hours with the device.
But it was worth it. The wireless range is actually opposite the larger 7390 and 7490 works stable. In 7390 I had dropped frames the WLAN cameras again. In 7490 this is no longer the case. Also, the change of menu items in the web interface of the 7490 significantly faster than in the 7390th
From me, therefore, a strong buy recommendation.
