    this range, check the connection from the computer to the router, and reboot your 
    computer.
    •If your router’s IP address was changed and you do not know the current IP address, 
    clear the router’s configuration to factory defaults. This sets the router’s IP address to 
    192.168.1.1. For more information, see 
    Factory Settings on page 178.
    •Make sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are using 
    Internet Explorer, click the Refresh button to be sure that the Java applet is loaded.
    •Try quitting the browser and launching it again.
    •Make sure that you are using the correct login information. The user name is admin, and 
    the default password is password. Make sure that Caps Lock is off when you enter this 
    information.
    •If you are attempting to set up your NETGEAR behind an existing router in your network, 
    use bridge mode or set up the router as an access point.
    •If you are attempting to set up your NETGEAR router as a replacement for an ADSL 
    gateway in your network, the router cannot perform many gateway services. For 
    example, the router cannot convert ADSL or cable data into Ethernet networking 
    information. NETGEAR does not support such a configuration.
    Cannot Access the Internet
    If you can access your router but not the Internet, check to see if the router can obtain an IP 
    address from your Internet service provider (ISP). Unless your ISP provides a fixed IP 
    address, your router requests an IP address from the ISP. You can determine whether the 
    request was successful using the Router Status screen.
    To check the WAN IP address: 
    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.
    3. Enter the 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 screen displays.
    4. Click the ADVANCED tab.
    The ADVANCED Home screen displays.
    5. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router did 
    not obtain an IP address from your ISP.
    If your router cannot obtain an IP address from the ISP, you might need to force your cable or 
    DSL modem to recognize your new router by restarting your network. For more information, 
    see 
    Sequence to Restart Your Network on page 168. 
    						
    							Troubleshooting 
    172 Nighthawk AC1750 Smart WiFi Router 
    If your router is still unable to obtain an IP address from the ISP, the problem might be one of 
    the following:
    •Your Internet service provider (ISP) might require a login program. 
    Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of 
    login.
    •If your ISP requires a login, the login name and password might be set incorrectly.
    •Your ISP might check for your computer’s host name. 
    Assign the computer host name of your ISP account as the account name in the Internet 
    Setup screen.
    •If your ISP allows only one Ethernet MAC address to connect to Internet and checks for 
    your computer’s MAC address do one of the following:
    -Inform your ISP that you have bought a new network device, and ask them to use the 
    router’s MAC address.
    -Configure your router to clone your computer’s MAC address.
    If your router was assigned an IP address but your computer does not load any web pages 
    from the Internet, it might be due to one or more of the following reasons:
    •Your computer might not recognize any DNS server addresses. 
    A DNS server is a host on the Internet that translates Internet names (such as www 
    addresses) to numeric IP addresses. Typically, your ISP provides the addresses of one or 
    two DNS servers for your use. If you entered a DNS address during the router’s 
    configuration, reboot your computer, and verify the DNS address. You can configure your 
    computer manually with DNS addresses, as explained in your operating system 
    documentation.
    •The router might not be configured as the TCP/IP gateway on your computer.
    If your computer obtains its information from the router by DHCP, reboot the computer, 
    and verify the gateway address.
    •You might be running login software that is no longer needed.
    If your ISP provided a program to log you in to the Internet (such as WinPoET), you no 
    longer need to run that software after installing your router. You might need to go to 
    Internet Explorer and select Tools > Internet Options, click the Connections tab, and 
    select the Never dial a connection radio button.
    Troubleshoot PPPoE
    If you are using PPPoE, try troubleshooting your Internet connection.
    To troubleshoot a PPPoE connection:
    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. 
    						
    							Troubleshooting

    A login screen displays.
    3. Enter the 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 screen displays.
    4. Click the ADVANCED tab.
    The ADVANCED Home screen displays.
    5. Click the Connection Status button. 
    The Connection Status screen displays.
    6. Check the Connection Status screen to see if your PPPoE connection is working.
    If you are not connected, click the Connect button. 
    The router continues to attempt to connect indefinitely.
    7. If you cannot connect after several minutes, the router might be set up with an incorrect 
    service name, user name, or password, or your ISP might be experiencing a provisioning 
    problem.
    Unless you connect manually, the router does not authenticate using PPPoE until data is 
    transmitted to the network.
    Troubleshoot Internet Browsing
    If your router can obtain an IP address but your computer is unable to load any web pages 
    from the Internet, check the following:
    •Your computer might not recognize any DNS server addresses. A DNS server is a host 
    on the Internet that translates Internet names (such as www addresses) to numeric IP 
    addresses.
    Typically, your ISP provides the addresses of one or two DNS servers for your use. If you 
    entered a DNS address during the router’s configuration, restart your computer.
    Alternatively, you can configure your computer manually with a DNS address, as 
    explained in the documentation for your computer.
    •The router might not be configured as the default gateway on your computer.
    Reboot the computer and verify that the router address (www.routerlogin.net) is listed by 
    your computer as the default gateway address.
    •You might be running login software that is no longer needed. If your ISP provided a 
    program to log you in to the Internet (such as WinPoET), you no longer need to run that 
    software after installing your router. You might need to go to Internet Explorer and select 
    Tools > Internet Options, click the Connections tab, and select the Never dial a 
    connection radio button. 
    						
    							Troubleshooting 
    174 Nighthawk AC1750 Smart WiFi Router 
    Changes Not Saved
    If the router does not save the changes you make in the router interface, do the following:
    •When entering configuration settings, always click the Apply button before moving to 
    another screen or tab or your changes are lost. 
    •Click the Refresh or Reload button in the web browser. It is possible that the changes 
    were made, but the old settings are in the web browser’s cache.
    Wireless Connectivity
    If you are experiencing trouble connecting wirelessly to the router, try to isolate the problem: 
    •Does the wireless device or computer that you are using find your wireless network?
    If not, check the WiFi LED on the front of the router. If it is off, you can press the WiFi 
    On/Off button on the router to turn the router wireless radios back on.
    If you disabled the router’s SSID broadcast, then your wireless network is hidden and 
    does not display in your wireless client’s scanning list. (By default, SSID broadcast is 
    enabled.)
    •Does your wireless device support the security that you are using for your wireless 
    network (WPA or WPA2)?
    •If you want to view the wireless settings for the router, use an Ethernet cable to connect a 
    computer to a LAN port on the router. Then log in to the router and select BASIC > 
    Wireless. 
    Note:Be sure to click the Apply button if you change settings.
    If your wireless device finds your network, but the signal strength is weak, check these 
    conditions:
    •Is your router too far from your computer or too close? Place your computer near the 
    router, but at least 6 feet (1.8 meters) away and see whether the signal strength 
    improves.
    •Are objects between the router and your computer blocking the wireless signal?
    Troubleshoot Your Network Using the Ping Utility
    Most network devices and routers contain a ping utility that sends an echo request packet to 
    the designated device. The device then responds with an echo reply. You can easily 
    troubleshoot a network using the ping utility in your computer or workstation.  
    						
    							Troubleshooting 
    175  Nighthawk AC1750 Smart WiFi Router
    Test the LAN Path to Your Router
    You can ping the router from your computer to verify that the LAN path to your router is set up 
    correctly.
    To ping the router from a Windows computer:
    1. From the Windows toolbar, click Start and select Run.
    2. In the field provided, type ping followed by the IP address of the router, as in this example:
    ping www.routerlogin.net
    3. Click the OK button.
    You should see a message like this one:
    Pinging  with 32 bytes of data
    If the path is working, you see this message:
    Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
    If the path is not working, you see this message:
    Request timed out
    If the path is not functioning correctly, you might be experiencing one of the following 
    problems:
    •Wrong physical connections
    For a wired connection, make sure that the numbered LAN port LED is lit for the port to 
    which you are connected.
    Check that the appropriate LEDs are lit for your network devices. If your router and 
    computer are connected to a separate Ethernet switch, make sure that the link LEDs are 
    lit for the switch ports that are connected to your computer and router.
    •Wrong network configuration
    Verify that the Ethernet card driver software and TCP/IP software are both installed and 
    configured on your computer. 
    Verify that the IP address for your router and your computer are correct and that the 
    addresses are on the same subnet.
    Test the Path from Your Computer to a Remote Device
    After verifying that the LAN path works correctly, test the path from your computer to a 
    remote device.
    1. From the Windows toolbar, click the Start button and select Run.
    2. In the field provided, type:
    ping -n 10  
    						
    							Troubleshooting 
    176 Nighthawk AC1750 Smart WiFi Router 
    where  is the IP address of a remote device such as your ISP DNS server.
    If the path is functioning correctly, messages display that are similar to those shown in Test 
    the LAN Path to Your Router on page 175.
    If you do not receive replies, check the following:
    •Check that the IP address of your router is listed on your computer as the default 
    gateway. If DHCP assigns the IP configuration of your computers, this information is not 
    visible in your computer Network Control Panel. Verify that the IP address of the router is 
    listed as the default gateway.
    •Check to see that the network address of your computer (the portion of the IP address 
    specified by the subnet mask) is different from the network address of the remote device.
    •Check that your cable or DSL modem is connected and functioning.
    •If your ISP assigned a host name to your computer, enter that host name as the account 
    name in the Internet Setup screen.
    •Your ISP might be rejecting the Ethernet MAC addresses of all but one of your 
    computers.
    Many broadband ISPs restrict access by allowing traffic only from the MAC address of 
    your broadband modem. Some ISPs additionally restrict access to the MAC address of a 
    single computer connected to that modem. If your ISP does this, configure your router to 
    “clone” or “spoof” the MAC address from the authorized computer.
