AC1600 WiFi Cable Modem Router

Introduction

The AC1600 WiFi Cable Modem Router Model C6250, in this manual referred to simply as

the modem router, provides you with an easy and secure way to set up a WiFi home network

with fast access to the Internet over a cable network with support for up to 680 Mbps. It lets

you block unsafe Internet content and applications and protects the devices that you connect

to your home or guest network.

The modem router provides one coaxial cable connector, two 10/100/1000 LAN Gigabit

Ethernet ports, and one USB 2.0 port. In addition, the modem router supports WiFi

connection speeds up to

1

300

Mbps in the 2.4 GHz band for 802.11n devices and up to

1300

Mbps in the 5 GHz band for 802.11ac devices. Both 2.4 GHz and 5 GHz bands can be

active simultaneously.

For information about setting up your new modem router, see the

AC1600 WiFi Cable

Modem Router Model C6250 Quick Start Guide

that comes in the package. This chapter

provides supplemental information that might help you with the setup.

For optimal performance, keep the modem router vertical in the stand and do not detach the

stand. Do not mount the modem router to a wall; it is not suitable for wall mounting. For more

information, see
