Yes and no. If your modem is easily accessible, has an empty port AND a close by electrical outlet and there is an outlet where you want to locate the hub - you could be up and running in 10 - 15 minutes.
It took me about 30 minutes as I needed a ladder, had reroute a long extension cord to reach an almost inaccessible outlet for the main orb, and find an asthetically suitable location with an outlet for the second.
Our than that it is super easy. Plug in the network cable and power, load an app on your phone, name the new network and password, answer some simple questions, push a button and wait a few minutes and you're up and running.
Our house is over 3300 square feet, two stories and the property is long. We now have very strong wifi throughout the house and property. Works very well for us.
