    3.   Specify Your Internet Settings
    Usually, the quickest way to set up the modem router to use your Internet connection is to allow 
    the modem router to detect the Internet connection when you first access the modem router with 
    a web browser. You can also customize or specify your Internet settings. 
    This chapter contains the following sections:
    •Specify the Cable Connection Starting Frequency 
    •View Modem Router Initialization 
    •Manually Set Up the Internet Connection 
    •Specify an IPv6 Internet Connection 
    •Change the MTU Size

    Specify the Cable Connection Starting Frequency
    The starting frequency is automatically generated. For most Internet connections, you do not 
    need to specify this information. If you must enter a starting frequency, contact your Internet 
    provider.
    To change the starting frequency:
    1.  Launch 
     a  web  browser  from  a  computer  or  mobile  device  that  is  connected  to  the 
    network.
    2.  T
    ype  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  Cable 
     Connection.
    The page displays the status of all downstream and upstream channels.
    5.  In 
    the  Starting  Frequency  field,  type  a  number.

    View Modem Router Initialization 
    You can track the initialization procedure of the modem router and get details about the 
    downstream and upstream cable channel. The time is displayed after the modem router is 
    initialized.
    The modem router automatically goes through the following steps in the provisioning  process:
    1.  Scans 
    and  locks  the  downstream  frequency  and  then  ranges  the  upstream  channels.
    2. Obtains 
     a  WAN  address  for  the  modem  router.
    3.  Connects 
     to  the  Internet.
    To view the status of the modem router initialization:
    1. Launch 
     a  web  browser  from  a  computer  or  mobile  device  that  is  connected  to  the 
    network.
    2.  T
    ype  http://routerlogin.net  or http://192.168.0.1.
    A login window opens.
    3.  Enter 
    the  modem  router  user  name  and  password.

     The default password is password . The user name and 
    password are case-sensitive.
    The BASIC Home page displays.
    4.  Select  Cable 
     Connection.
    The Startup Procedure section displays the initialization progress. The page also displays 
    the status of all downstream and upstream channels.(Scroll down to view all the 
    channels.) The number of downstream and upstream channels that are locked depends 
    on the number of channels that your Internet provider uses.

    Manually Set Up the Internet Connection
    In most situations, you do not need to change these settings. We recommend that you use 
    the default settings for DHCP because most cable Internet services provide the IP address 
    through DHCP.
    To specify the Internet connection settings:
    1. 
    Launch 
     an  Internet  browser  from  a  computer  or  mobile  device  that  is  connected  to  the 
    network.

    Name  (If  Required)  field.
    6.  If 
    your  Internet  connection  requires  a  domain  name,  type  it  in  the  Domain  Name (If 
    Required)  field. 
    For the other sections in this page, the default settings usually 
     work, but you can change 
    them.
    7.  Select 
    an  Internet  IP Address  radio  buttons:
    •Get 
    Dynamically from ISP . Your ISP uses DHCP to assign your IP address. Your ISP 
    automatically assigns these addresses. 
    						
    							Specify Your Internet Settings

    •Use Static IP Address
    address that your ISP assigned. The gateway is the ISP modem router to which your 
    modem router connects.
    8. Select  a  Domain  Name  Server  (DNS) Address  radio  button:
    •Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your 
    ISP automatically assigns this address.

    this option. Enter the IP address of your ISP’s primary DNS server. If a secondary 
    DNS server address is available, enter it also. 
    9. Select  a  Router  MAC Address  radio  button:
    •Use Default Address. Use the default MAC address.
    •Use Computer MAC Address. The modem router captures and uses the MAC 
    address of the computer that you are now using. You must use the one computer that 
    the ISP allows.

     This method passes more information to LAN devices, but some 
    IPv6 systems might not support the DHCP client function.
    • Auto Config. 
     This is the default setting.
    This setting specifies how the modem router assigns IPv6 addresses to the home  network (the LAN).

    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 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: 
    						
    							Specify Your Internet Settings 28
    AC1900 Cable Modem Voice Router 
    •
    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
    - Y
    ahoo email
    - MSN portal
    - America Online’
     s DSL service
    • Y
    ou use VPN and experience severe performance problems.
    •Y
    ou used a program to optimize MTU for performance reasons, and now you are 
    experiencing 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  mobile  device  that  is  connected  to  the 
    network.
    2.  T
    ype  http://www.routerlogin.net  or http://www.routerlogin.com .
    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  ADV
     ANCED  >  Setup  >  WAN  Setup .  
    						
    							Specify Your Internet Settings 29

    5. 
    In  the  MTU  Size  field,  enter  a  value  from  64  to  1500.
    6.  Click 
    the  Apply  button.
    Your settings are 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. The following table describes common MTU sizes and 
    applications. 
    Table 2.  Common MTU sizes   
    MTUApplication
    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 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 use large email attachments, for example.
