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 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

The modem router lets you access your network from anywhere within the operating range of your WiFi network. However, the operating distance or range of your WiFi connection can vary significantly depending on the physical placement of your modem router. For example, the thickness and number of walls the WiFi signal passes through can limit the range.

For best results, place your modem router according to the following guidelines:

• Place your modem router on an upper floor of a multifloor home or of

fice.

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

devices operate, and within line of sight to your WiFi 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

- Baby monitors

- Base of a cordless phone

Manage the MTU Size

The maximum transmission unit (MTU) is the largest data packet that a network device transmits.

MTU Concepts

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 uses 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 experience severe performance problems.

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

experiencing connectivity or performance problems.

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. The following table describes common MTU sizes and applications.

Table 4. 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.)

WARNING:

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. Change the MTU only if you are sure that it is necessary for your ISP connection.

AC1600 WiFi Cable Modem Router

Manage the Basic WiFi Settings and WiFi Security of the Main Network

The modem router comes with preset security. This means that the WiFi network name (SSID), network key (password), and security option (encryption protocol) are preset in the factory. The preset SSID and password are uniquely generated for every device to protect and maximize your WiFi security. You can find the preset SSID and password on the product label (see

Product Label on page 23).

IMPORTANT:

NETGEAR recommends that you do not change your preset security settings. If you decide to change your preset security settings, make a note of the new settings and store the note in a safe place where you can easily find it.

View or Change the Basic WiFi Settings

You can view or change the basic WiFi settings and WiFi security. The modem router simultaneously supports the 2.4 GHz band for 802.11b/g/n devices and the 5 GHz band for

802.11a/n/ac devices.

Tip: If you decide to change the WiFi settings of the modem router’s main

network, use a wired connection to avoid being disconnected when the new WiFi settings take effect.

 To view or change basic WiFi settings for main WiFi network:

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

network.

Note: NETGEAR recommends that you do not change the default SSID. If you must

change the SSID, enter a 32-character (maximum), case-sensitive name in this field.

Channel From the Channel menu, select Auto for automatic channel selection or select an

individual channel. The default selection is Auto and the channel that is in use is stated next to the menu.

Note: Do not change the channel unless you experience interference (shown by lost

connections or slow data transfers). If this situation occurs, experiment with different channels to see which one is the best.

Note: If you use multiple WiFi access points (APs), reduce interference by selecting

different channels for adjacent APs. NETGEAR recommends a channel spacing of four channels between adjacent APs (for example, use Channels 1 and 5, or 6 and 10).

Mode From the Mode menu, select one of the following modes:

• Up to 54 Mbps. Legacy mode. This mode allows 802.11n, 802.11g, and 802.11b

devices to join the network but limits 802.11n devices to functioning at up to 54

• Up to 145 Mbps. Neighbor-friendly mode for reduced interference with neighboring

WiFi networks. This mode allows 802.11n, 802.11g, and 802.11b devices to join the network but limits 802.11n devices to functioning at up to 145 default mode.

• Up to 300 Mbps. Performance mode. This mode allows 802.11n, 802.11g, and

Security Options

This information applies to the 2.4 GHz WiFi network.

Note: NETGEAR recommends that you do not change your preset security settings (WPA2-PSK [AES]).

If you must change the WiFi security, select one of the following WiFi security options for the modem router’s WiFi network:

• None. An open WiFi network that does not provide any security. Any WiFi device can join the network.

NETGEAR recommends that you do not use an open WiFi network.

• WEP. Wired Equivalent Privacy (WEP) security is a legacy authentication and data encryption mode

that is superseded by WPA-PSK and WPA2-PSK. The WEP option displays only if you select Up to 54 Mbps from the Mode menu. For information about configuring WEP, see

Security for the Main WiFi Network on page 43.

• WPA-PSK [TKIP]. WPA provides a secure connection but is superseded by WPA2. The WPA-PSK

[TKIP] option displays only if you select Up to 54 Mbps from the Mode menu.

To use this type of security, in the Passphrase field, enter a phrase of 8 to 63 characters. To join the modem router’s WiFi network, a user must enter this passphrase.

• WPA2-PSK [AES]. This type of security is the default setting and enables WiFi devices that support

WPA2 to join the modem router’s 2.4 GHz WiFi network. If you did not change the passphrase, the default passphrase displays. The default passphrase is printed on the product label (see on page 23). WPA2 provides a secure connection but some older WiFi devices do not detect WPA2 and support only WPA. If your network includes such older devices, select WPA-PSK [TKIP] + WPA2-PSK [AES] security.

NETGEAR recommends that you do not change the default passphrase. If you must change the passphrase, in the Passphrase field, enter a phrase of 8 to 63 characters. To join the modem router’s WiFi network, a user must enter this passphrase.

• WPA-PSK [TKIP] + WPA2-PSK [AES]. This type of security enables WiFi devices that support either

WPA or WPA2 to join the modem router’s 2.4 GHz WiFi network. However, WPA-PSK [TKIP] is less secure than WPA2-PSK [AES] and limits the speed of WiFi devices to 54 Mbps.

To use this type of security, in the Passphrase field, enter a phrase of 8 to 63 characters. To join the modem router’s WiFi network, a user must enter this passphrase.

• WPA/WPA2 Enterprise. This type of security requires that your WiFi network can access a RADIUS

server. For information about configuring WPA/WPA2 Enterprise, see

WiFi Security on page 41.
