    The WPS process automatically sets up your wireless computer with the network 
    password when it connects. The modem router WPS screen displays a confirmation 
    message. 
    Specify Basic WiFi Settings
    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. You can find the preset SSID and password on the modem router label. 
    Note:The preset SSID and password are uniquely generated for every 
    device to protect and maximize your wireless security.
    NETGEAR recommends that you do not change your preset security settings. If you change 
    your preset security settings, make a note of the new settings and store it in a safe place 
    where you can easily find it.
    If you use a wireless computer to change the wireless network name (SSID) or other wireless 
    security settings, you are disconnected when you click the Apply button. To avoid this 
    problem, use a computer with a wired connection to access the modem router.
    To specify basic wireless settings:
    1. Launch a web browser from a computer or wireless device that is connected to the 
    network.
    2. Type http://routerlogin.net or http://192.168.0.1.

    Select  Wireless.
    5. In the Region list, select your region. In some locations, you cannot change this set\
    ting.
    6.  (Optional) Select the Enable W
     ireless Isolation checkbox.
    When wireless isolation is enabled, computers and devices that join the \
    network have 
    access to the Internet, but not to each other
     .
    7.  T
    o turn off the wireless radio, scroll down and clear the  Enable Wireless Gateway Radio 
    check box.
    If you clear this check box, you cannot use WiFi to connect to the modem router.
    8.  T
    o control the SSID broadcast, select or clear the  Enable SSID Broadcast check box.
    When this check box is selected, the modem router broadcasts its network\
     name (SSID) 
    so that it displays when you scan for local WiFi networks on your comput\
    er or wireless 
    device.
    9.  T
    o change the network name (SSID), type a new name in the  Name (SSID) field.
    The name can be up to 32 characters long and it is case-sensitive. The default SSID is 
    randomly generated and is on the modem router’s
      label. If you change the name, make 
    sure to write down the new name and keep it in a safe place.
    10.  T
    o change the wireless channel, select a number in the  Channel list.
    In some regions, not all channels are available. Do not change the chann\
    el unless you 
    experience interference (shown by lost connections or slow data transfe\
    rs). If this 
    happens, experiment with dif
    
    ferent channels to see which is the best. 
    When you use multiple access points, it is better if adjacent access poi\
    nts use different 
    channels to reduce interference. 
     The recommended channel spacing between adjacent 
    access points is four channels (for example, use Channels 1 and 5, or 6\
     and 10).
    11.  T
    o change the mode, select it from the  Mode list.

    If you cannot connect wirelessly, check the following:
    •Is your computer or wireless device connected to another wireless network in your 
    area? Some wireless devices automatically connect to the first open network without 
    wireless security that they discover.
    •Is your computer or wireless device trying to connect to your network with its old 
    settings (before you changed the settings)? If so, update the wireless network 
    selection in your computer or wireless device to match the current settings for your 
    network.
    Change the WiFi Security Option
    Your modem router comes with preset WPA2 or WPA security. The password that you enter to 
    connect to your network is unique to your modem router and is on the label. NETGEAR 
    recommends that you use the preset security, but you can change the settings. NETGEAR 
    recommends that you do not disable security.
    To change the WPA settings:
    1. Launch a web browser from a computer or wireless device that is connected to the 
    network.

    Set Up a WiFi Guest Network
    A guest network allows visitors at your home to use the Internet without\
     using your wireless  security key. You can add a guest network to each wireless network: 2.4 GHz b/g/n and  
    5.0 GHz a/n. 
    To set up a guest network:

    •Enable Guest Network. When this check box is selected, the guest network is 
    enabled, and guests can connect to your network using the SSID of this profile.
    •Enable SSID Broadcast. If this check box is selected, the wireless access point 
    broadcasts its name (SSID) to all wireless stations. Stations with no SSID can adopt 
    the correct SSID for connections to this access point.
    •Allow guest to see each other and access my local network. If this check box is 
    selected, anyone who connects to this network has access to your local network, not 
    just Internet access.
    6.Give the guest network a name.
    The guest network name is case-sensitive and can be up to 32 characters. You then 
    manually configure the wireless devices in your network to use the guest network name in 
    addition to the main SSID. 
    7.Select a radio button for a security option. 
    The WPA2 options use the newest standard for the strongest security, but some older 
    computers and wireless devices cannot use it. NETGEAR recommends that you select 
    the WPA-PSK [TKIP] + WPA2-PSK [AES] radio button. This setting protects your WiFi 
    network and lets computers and wireless devices can connect to the WiFi network by 
    using either WPA2 or WPA security.
    8.Click the Apply button. 
    Your settings are saved.
    Control the Wireless Radio
    The modem router has an internal wireless radio that broadcasts signals in the 2.4 GHz 
    range. By default, it is on so that you can connect wirelessly to the modem router. When the 
    wireless radio is off, you can still use an Ethernet cable for a LAN connection to the modem 
    router.
    You can turn the wireless radio on and off with the WiFi On/Off button on the modem router, or 
    you can log in to the modem router and enable or disable the wireless radio. If you are close 
    to the modem router, it might be easier to press its WiFi On/Off button. If you are away from 
    the modem router or have already logged in it might be easier to enable or disable the radio. 
    Use the WiFi On/Off Button
    To turn the wireless radios off and on with the WiFi On/Off button:
    Press the WiFi On/Off button on the modem router for two seconds.
    If you turned off the wireless radio, the WiFi On/Off LED and the WPS LED turn off. If you 
    turned on the wireless radio, the WiFi On/Off LED and the WPS LED light.

    router to 
    turn them back on. You must press the WiFi On/Off  button again for two seconds to 
    turn the wireless radio back on.
    To enable or disable the wireless radio:
    1.  Launch a web browser from a computer or wireless device that is connecte\

    the Network Explorer on a Vista Windows computer) to configure the modem router’s 
    wireless settings through WPS. 
    5. (Optional) Select or clear the Disable Gateway’s PIN check box.
    The PIN function might temporarily be disabled when the modem router detects 
    suspicious attempts to break into the modem router’s wireless settings by using the 
    modem router’s PIN through WPS. You can manually enable the PIN function by clearing 
    the Disable Gateway’s PIN check box.
    6. (Optional) Select or clear the Keep Existing Wireless Settings check box.
    By default, the Keep Existing Wireless Settings check box is selected. NETGEAR 
    recommends that you leave this check box selected.
    If you clear this check box, the next time a new wireless client uses WPS to connect to 
    the modem router, the modem router wireless settings change to an automatically 
    generated random SSID and security key. 
    7. Click the Apply button.
    Your changes are saved.
    Set Up a Wireless Card Access List
    By default, any wireless computer or device that is configured with the correct SSID is 
    allowed access to your wireless network. For increased security, allow only specific wireless 
    computers and devices to access the wireless network based on their MAC addresses.
