Got one a couple months ago after complaing about the old one and it constantly dropping cameras and equipment. Only thing that had to be done is if you have any cameras, they will all have to be deleted and then re-setup. Also if you may have to change your password for access to your home wireless network for any devices you have. The router comes with a new one, but it can be changed in the setup back to what you had on your old one. I just left it and changed my devices as it was time to change mine anway.
Much better speeds and range on the new units.
