Because Telekom has changed my connection to IP telephony had a new router IP capable. I chose the 7360 because it is a good 90 cheaper than the 7390 but from a performance point of both boxes are almost identical. (Both boxes have the same computer) The lack of internal memory I have supplemented with a USB stick. This was recognized by the box immediately and activated. The interior of the box with the setup wizard was finished in no time without any problems. Update to the latest software also via the wizard. Just perfect. Contact and WLAN access I transferred from a backup of the old box. This has also worked out well. Otherwise, the box is very stable and reliable. No crashes or reboots. Some users criticize the lack of WiFi performance. Now that's in almost all routers do not have antennas outside the case. But this can fix it for about 35 with a Fritz Repeater. In my case the power goes through 2 rooms through out without repeaters. Surely it also plays an important role as the texture of the walls (concrete, brick, drywall, etc.) and of course by the reception quality of the device. Some of which are quite different. Anyway, I'm happy and forgiving full marks :-)
