Came with zero instructions for set up, just a QR code. Scanned the QR code and it took me to install an app. I begrudgingly installed it.
The app had me hit next a few times before scanning a different QR code on the bottom of the modem. That was the entire process.
I guess you just have to pay for installation if you don't have a smart phone? It offered for $150+ when I agreed to the new modem.
