SETUP
Setting up the RE7000 is very easy so aside choosing your preferred language you will also need to set a new password, choose how you'd like to configure the unit (access point or range extender), choose the 5GHz/2.4GHz networks you'd like to extend and check the spot finder feature to see if you've placed the unit optimally.
Things are even faster with the 1750E by AVM since you just have to choose your preferred language and pick the 5GHz/2.4GHz signals you'd like to extend.
The devolo repeater is just as easy to setup as the other two so again you will have to choose between Access Point and Repeater mode, pick the 5GHz/2.4GHz signals you'd like to extend and that's it.
