Position Your Modem Router

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.

Position your modem router according to the following guidelines:

• Place your modem router near the center of the area where your computers and other

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.

Cable the Modem Router in a Simple Network

The modem router comes configured to work as both a modem and a router. You can share your Internet connection without connecting the modem router to a router or gateway.

Hardware Setup

Nighthawk AC1900 WiFi Cable Modem Router

 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: For Xfinity cable Internet service, Comcast Xfinity recommends

connecting your modem router to a cable wall outlet.

2. Connect the power adapter provided in the package to the modem router and plug the

power adapter in to an electrical outlet.

3. Press the Power On/Off button on the rear panel of the modem router.

The Power LED lights green.

You can log in to the modem router to view or change its settings.

Cable Your Modem Router to a Router and Use Bridge Mode

If you want to cable the modem router to a router, 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). This turns the modem router into a bridged modem

 To cable your modem router to a gateway or 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.

2. Connect the power adapter to the modem router and plug the power adapter into an

electrical outlet. The Power LED lights green.

3. On your computer or wireless device, find and select the WiFi network.

The WiFi network name is on the product label.

4. Join the WiFi network and enter the WiFi password.

The password is on the product label. Your wireless device connects to the WiFi network.

5. Launch a web browser.

6. Type http://routerlogin.net or http://192.168.0.1.

A login screen displays.

The BASIC Home screen displays.

8. Select ADV

9. Select the No radio button.

With this setting, the modem router works as a bridge and obtains IP addresses from the cable Internet provider.

10. Click the Apply button.

Your change is saved.

11. Follow the instructions that came with your router or gateway to connect it to the modem

CAUTION:

Once the modem router is in bridge mode, you must connect only one device (your router) to a modem router LAN port. In most cases, Internet service providers provide only one public IP address and connecting multiple devices will cause conflicts and will cause your devices to stop working.

Set Up Your Internet Service with Comcast Xfinity

Set up Internet service by using Comcast Xfinity’s self-activation process. If you are unable to self-activate your modem router, call Comcast Xfinity customer service. After you complete the setup, perform a speed test.

Use Self-Activation to Set Up Your Internet Connection

Before you start the self-activation process, make sure that your account number, account phone number, and login information (your email address or user name and password) are nearby.

 To set up your Internet connection with Comcast Xfinity’s self-activation process:

1. Close all web browsers.

Hardware Setup

2. Launch a web browser.

You are redirected to the Xfinity self-activation page. If you are not redirected to the Xfinity self-activation page, visit www.comcast.com/activate.

3. Provide your Xfinity credentials and complete the selfactivation process.

This process might take up to 15 minutes, during which the modem router reboots a couple times.

Call Comcast Xfinity to Set Up Your Internet Connection

If you are unable to self-activate your modem router, call Comcast Xfinity customer service. Before you call Comcast Xfinity, make sure that your account number, account phone

4. If you do not get an Internet connection with the modem router

, ask the Comcast Xfinity representative to look for your modem router online, and do one of the following depending on what the representative tells you about your modem router:

• If the modem router is not visible, the Comcast Xfinity representative can give you

instructions to verify why the modem router does not connect with your high-speed Internet service.

• If the modem router is visible to the Comcast Xfinity representative, reboot the

modem router

look for your modem router online, and do one of the following depending on what your cable Internet provider tells you about your modem router:

• If the modem router is not visible, your cable Internet provider can give you

instructions to verify why the modem router does not connect with your high-speed Internet service.

• If the modem router is visible to your cable Internet provider, reboot the computer,

laptop, or home gateway that is connected to the modem router. Try checking your online status again.

Change the MTU Size

The maximum transmission unit (MTU) is the largest data packet a network device transmits. When one network device communicates across the Internet with another, the data packets travel through many devices along the way. If a device in the data path has a lower MTU setting than the other devices, the data packets must be split or “fragmented” to accommodate the device with the smallest MTU.

The best MTU setting for NETGEAR equipment is often the default value. In some situations, changing the value fixes one problem but causes another. Leave the MTU unchanged unless one of these situations occurs:

• You experience problems connecting to your ISP or other Internet service, and the

technical support of either the ISP or NETGEAR recommends changing the MTU setting. These web-based applications might require an MTU change:

- A secure website that does not open, or displays only part of a web page

- Yahoo email

- MSN portal

- America Online’s DSL service

• You use VPN and have severe performance problems.

• You used a program to optimize MTU for performance reasons, and now you have

connectivity or performance problems.

Note: An incorrect MTU setting can cause Internet communication

problems. For example, you might not be able to access certain websites, frames within websites, secure login pages, or FTP or POP servers.

 To change the MTU size:

1. Launch an Internet browser from a computer or wireless device that is connected to the

network.

2. Type http://www.routerlogin.net or http://www.routerlogin.com.

A login screen displays.

Specify Your Internet Settings

The default password is password. The user name and

password are case-sensitive. The BASIC Home screen displays.

4. Select ADV

ANCED > Setup > WAN Setup.

5. In the MTU Size field, enter a value from 64 to 1500.

6. Click the Apply button.

Your change is saved.

If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes away applications.

. The following table describes common MTU sizes and

Table 1. Common MTU sizes

MTU Application

1500 The largest Ethernet packet size. This setting is typical for connections that do not use

PPPoE or VPN, and is the default value for NETGEAR modem routers, adapters, and

switches. 1492 Used in PPPoE environments. 1472 Maximum size to use for pinging. (Larger packets are fragmented.) 1468 Used in some DHCP environments. 1460 Usable by AOL if you do not have large email attachments, for example.
