You can send it back, but (supposedly) if you do so they charge you a fee to send a tech out in the future. I say supposedly because it seems like a weed-out warning to reduce support tickets from people who made their own problems, but I haven’t had to find out since my Sonic fiber has been flawless for two years. There’s an ONT on the wall where the fiber comes through, providing one data jack and one phone jack. I just plug an ethernet cable between it and my FreeBSD router PC, request a DHCP lease on that interface, and go.
