Hardware Overview and Setup 9 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 Position Your Modem Router on page 13. 1. Actual data throughput and WiFi coverage will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate and WiFi coverage. NETGEAR makes no express or implied representations or warranties about this product’s compatibility with any future standards.
