Position Your Gateway
The modem router lets you access your network anywhere within the operating range of your
wireless network. However, the operating distance or range of your wireless connection can
vary significantly depending on the physical placement of your modem router. For example,
the thickness and number of walls the wireless signal passes through can limit the range.
Additionally, other wireless access points in and around your home might affect your modem
router’
or any other device that emits a wireless signal for network access.
s signal. Wireless access points are modem routers, repeaters, WiFi range extenders,
Position your modem router according to the following guidelines:
• Place your modem router near the center of the area where your computers and other
devices operate, and within line of sight to your wireless devices.

• Make sure that the modem router is within reach of an AC power outlet and near Ethernet
cables for wired computers.
• Place the modem router in an elevated location, minimizing the number walls and ceilings
between the modem router and your other devices.
• Place the modem router away from electrical devices such as these:
- Ceiling fans
- Home security systems
- Microwaves
- Computers
- Base of a cordless phone
- 2.4 GHz cordless phone
• Place the modem router away from large metal surfaces, large glass surfaces, and
insulated walls such as these:
- Solid metal door
- Aluminum studs
- Fish tanks
- Mirrors
- Brick
- Concrete
• (Optional) If you have adjacent access points, use different radio frequency channels to
reduce interference.
Cable Your Modem Router
The most common way to cable your modem router is the simplest, without any other routers
or gateways on the same network. You can also cable the modem router to another router or
gateway and log in to the modem router to specify this setting.

To cable your modem router:
1. Connect a coaxial cable.
Use the coaxial cable that your cable company provides to connect the cable port on the
modem
router to a cable wall outlet or a line splitter.
Note: If Charter is your cable Internet service provider (ISP), Charter
recommends connecting your modem router directly to a cable wall
outlet. If you must use a splitter, use a splitter that is rated at 3.5 dBmv.
2. Connect the power adapter to the modem router and plug the power adapter in to an
electrical outlet.

Cable Your Modem Router to a Router or Gateway
If you want to cable the modem router to a router or gateway, then you must log in to the
modem router and change its Router Mode setting. Changing this setting prevents certain
network conflicts that can occur when two devices on the same network perform routing
functions such as network address translation (NAT) and DHCP (assigning IP addresses to
devices on the network).
