I bought the box as a replacement for my old 7170, which now suffers from a bit of old age. The installation was therefore simple: 1. exported settings from 7170 2. imported settings in 3370 3. Small control especially new settings The upgrade has felt lasted only a few minutes, went very smoothly and everything was set up as before.
For many functions, I can not say anything because I use the box exclusively as a router.
