Connect Your Modem Router to a Router After Installation and Activation

During the installation and activation, you must connect the modem router directly to a computer. After installation and activation, you can connect the modem router to a router.

If you want to connect your modem router to a router, you must disable NAT. With NAT disabled, to avoid conflicting with the other router on the network, the modem router does not use NAT.

To disable NAT and connect your modem router to a router after installation and activation:

1. Connect a coaxial cable.

Use the coaxial cable that is provided by your cable company to connect the cable port on the modem router to a cable wall outlet.

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.

Make sure that the cable is tightly connected.

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

The startup procedure takes about one minute. When the startup procedure is complete, the Power LED lights green.

3. On your WiFi-enabled computer or mobile device, find and select the WiFi network.

The WiFi network name is on the modem router label.

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

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.

Set Up a Default DMZ Server

The default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The modem router is programmed to recognize some of these applications and to work correctly with them, but other applications might not function well. In some cases, one local computer can run the application correctly if the IP address for that computer is entered as the default DMZ server.

DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network.

The modem router usually detects and discards incoming traffic from the Internet that is not a response to one of your local computers or a service that you configured on the Port Forwarding/Port Triggering page. Instead of discarding this traffic, the modem router canforward the traffic to one computer on your network. This computer is called the default DMZ server.

To set up a default DMZ server:

1. Launch a web browser from a computer or mobile device that is connected to the

modem router network.

2. Enter http://routerlogin.net or http://192.168.0.1.

A login window opens.

Change the LAN TCP/IP Settings

The modem router is preconfigured to use private IP addresses on the LAN side and to act as a DHCP server. The modem router’s default LAN IP configuration is as follows:

• LAN IP address. 192.168.0.1

• Subnet mask. 255.255.255.0

These addresses are part of the designated private address range for use in private networks and are suitable for most applications. If your network requires a different IP addressing scheme, you can change these settings.

You might want to change these settings if you need a specific IP subnet that one or more devices on the network use, or if you use competing subnets with the same IP scheme.

Specify the IP Addresses That the Modem Router Assigns

By default, the modem router acts as a Dynamic Host Configuration Protocol (DHCP) server. The modem router assigns IP, DNS server, and default gateway addresses to all computers connected to the LAN. The assigned default gateway address is the LAN address of the modem router.

These addresses must be part of the same IP address subnet as the modem router’s LAN IP

By default, the modem router acts as a DHCP server. The modem router assigns IP, DNS server, and default gateway addresses to all computers connected to the LAN. The assigned default gateway address is the LAN address of the modem router.

You can use another device on your network as the DHCP server, or specify the network settings of all your computers.

To disable the DHCP server feature in the modem router:

1. Launch a web browser from a computer or mobile device that is connected to the

modem router network.

2. Enter http://routerlogin.net or http://192.168.0.1.

A login window opens.

3. Enter the modem router user name and password.

The user name is admin. The default password is password. The user name and password are case-sensitive.

The BASIC Home page displays.

4. Select ADVANCED > Setup > LAN Setup.

The LAN Setup page displays.

5. Clear the Use Router as DHCP Server check box.

6. Click the Apply button.

Specify Network Settings User Manual70

7. (Optional) If this service is disabled and no other DHCP server is on your network, set your computer IP addresses manually so that they can access the modem router.

Reserve LAN IP Addresses

When you specify a reserved IP address for a computer on the LAN, that computer always receives the same IP address each time it accesses the modem router’s DHCP server. Assign reserved IP addresses to computers or servers that require permanent IP settings.

To reserve an IP address:

1. Launch a web browser from a computer or mobile device that is connected to the

modem router network.

2. Enter http://routerlogin.net or http://192.168.0.1.

A login window opens.

3. Enter the modem router user name and password.

The user name is admin. The default password is password. The user name and password are case-sensitive.

The BASIC Home page displays.

4. Select ADVANCED > Setup > LAN Setup.

5. In the Address Reservation section, click the Add button.

6. In the IP Address field, type the IP address to assign to the computer or server.

Choose an IP address from the modem router’s LAN subnet, such as 192.168.0.x.

Tip: If the computer is already on your network, you can copy its MAC

address from the Attached Devices page and paste it here.

8. Click the Apply button.

The reserved address is entered into the table.

The reserved address is not assigned until the next time the computer contacts the modem router’s DHCP server. Reboot the computer, or access its IP configuration and force a DHCP release and renew.

To edit a reserved address entry:

1. Select the radio button next to the reserved address.

2. Click the Edit button.

3. Change the settings.

Improve Network Connections With Universal Plug and Play

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.

If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications such as instant messaging or remote assistance (a feature in Windows XP), enable UPnP.

To enable Universal Plug and Play:

1. Launch a web browser from a computer or mobile device that is connected to the

modem router network.

2. Enter http://routerlogin.net or http://192.168.0.1.

A login window opens.

3. Enter the modem router user name and password.

Nighthawk AC1900 WiFi Cable Modem Router

status at the expense of more network traffic. Longer durations can compromise the freshness of the device status, but can significantly reduce network traffic.

7. Type the advertisement time to live in hops.

The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. Hops are the steps a packet takes between routers. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which is fine for most home networks. If you notice that some devices are not being updated or reached correctly, it might be necessary to increase this value.

8. Click the Apply button.

The UPnP Portmap Table displays the IP address of each UPnP device that is accessing the modem router and which ports (internal and external) that device opened. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address.

To refresh the information in the UPnP Portmap Table, click the Refresh button.

Dynamic DNS

Internet service providers (ISPs) assign numbers called IP addresses to identify each Internet account. Most ISPs use dynamically assigned IP addresses. This means that the IP address can change at any time. You can use the IP address to access your network remotely, but most people don’t know what their IP addresses are or when this number changes.

To make it easier to connect, you can get a free account with a Dynamic DNS service that lets you

use a domain name to access your home network. To use this account, you must set up

the modem router to use Dynamic DNS. Then the modem router notifies the Dynamic DNS service provider whenever its IP address changes. When you access your Dynamic DNS account, the service finds the current IP address of your home network and automatically connects you.

If your ISP assigns a private WAN IP address (su DNS service does not work because private addresses are not routed on the Internet.
