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

materials and construction, and network overhead, lower actual data throughput rate and WiFi coverage. NETGEAR makes no express or implied
