14 Troubleshooting This chapter provides information to help you diagnose and solve problems you might experience with your router. If you do not find the solution here, check the NETGEAR support site at http://support.netgear.com for product and contact information. The chapter contains the following sections: •Quick Tips on page 174 •Troubleshoot With the LEDs on page 174 •You Cannot Log In to the Router on page 176 •You Cannot Access the Internet on page 177 •Troubleshoot Internet Browsing on page 178 •Changes Are Not Saved on page 178 •Troubleshoot WiFi Connectivity on page 179 •Troubleshoot Your Network Using the Ping Utility on page 179 173
Quick Tips This section describes tips for troubleshooting some common problems. Sequence to Restart Your Network If you must restart your network, follow this sequence: 1.Turn off and unplug the modem. 2.Turn off the router. 3.Plug in the modem and turn it on.Wait two minutes. 4.Turn on the router and wait two minutes. Check Ethernet Cable Connections If your device does not power on, make sure that the Ethernet cables are securely plugged in.The Internet LED on the router is lit if the Ethernet cable connecting the router and the modem is plugged in securely and the modem and router are turned on. If one or more powered-on computers are connected to the router by an Ethernet cable, the corresponding numbered router LAN port LEDs light. WiFi Settings Make sure that the WiFi settings in the computer and router match exactly.The WiFi network name (SSID) and WiFi security settings of the router and WiFi computer must match exactly. If you set up an access list on the Advanced Wireless Settings page, you must add each WiFi computer’s MAC address to the router’s access list. Network Settings Make sure that the network settings of the computer are correct.Wired computers and computers that are connected over WiFi must use network IP addresses on the same network as the router.The simplest way to do this is to configure each computer to obtain an IP address automatically using DHCP. Some service providers require you to use the MAC address of the computer initially registered on the account.You can view the MAC address on the Attached Devices page. Troubleshoot With the LEDs By default, the router is set with standard LED settings. If you turned off the LEDs except the Power LED, you must return the LEDs to their standard settings for troubleshooting. For information about controlling the LED settings, see Turn the LEDs On or Off on page 12. Standard LED Behavior When the Router Is Powered On After you turn on power to the router, verify that the following sequence of events occurs: Troubleshooting 174 Nighthawk X4S AC2600 Smart WiFi Router
1.When power is first applied, verify that the Power LED is lit. 2.After about two minutes, verify the following: •The Power LED is solid white. •The Internet LED is lit. •The WiFi LED is lit unless you turned off the WiFi radio. You can use the LEDs on the front panel of the router for troubleshooting. Power LED Is Off or Blinking This could occur for a number of reasons. Check the following: •Make sure that the power adapter is securely connected to your router and securely connected to a working power outlet. •Make sure that you are using the power adapter that NETGEAR supplied for this product. •If the Power LED blinks slowly and continuously, the router firmware is corrupted.This can happen if a firmware upgrade is interrupted, or if the router detects a problem with the firmware. If the error persists, it is likely that a hardware problem exists. For recovery instructions, or help with a hardware problem, contact technical support at netgear.com/support. Power LED Stays Amber When the router is turned on, the Power LED lights amber for up to two minutes and then turns white. If the LED does not turn white, this indicates a problem with the router. If the Power LED is still amber three minutes after you turn on power to the router, do the following: •Cycle the power to see if the router recovers. •Press and hold the Reset button to return the router to its factory settings. For more information, see Factory Settings on page 183. If the error persists, a hardware problem might be the cause. Contact technical support at netgear.com/support. LEDs Never Turn Off When the router is turned on, the LEDs light for about 10 seconds and then turn off. If all the LEDs stay on, this indicates a fault within the router. If all LEDs are still lit one minute after power-up, do the following: •Cycle the power to see if the router recovers. •Press and hold the Reset button to return the router to its factory settings. For more information, see Factory Settings on page 183. If the error persists, a hardware problem might be the cause. Contact technical support at netgear.com/support. Troubleshooting 175 Nighthawk X4S AC2600 Smart WiFi Router
Internet or Ethernet Port LEDs Are Off If either the Ethernet port LEDs or the Internet LED does not light when the Ethernet connection is made, check the following: •Make sure that the Ethernet cable connections are secure at the router and at the modem or computer. •Make sure that power is turned on to the connected modem or computer. •Be sure that you are using the correct cable. When you connect the router’s Internet port to a modem, use the cable that was supplied with the modem.This cable can be a standard straight-through Ethernet cable or an Ethernet crossover cable. WiFi LED Is Off If the WiFi LED stays off, check to see if someone pressed the WiFi On/Off button on the router.This button turns the WiFi radios in the router on and off.The WiFi LED is lit when the WiFi radios are turned on. You Cannot Log In to the Router If you are unable to log in to the router from a computer on your local network, check the following: •If you are using an Ethernet-connected computer, check the Ethernet connection between the computer and the router. •Make sure that the IP address of your computer is on the same subnet as the router. If you are using the recommended addressing scheme, your computer’s address is in the range of 192.168.1.2 to 192.168.1.254. •If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and Mac OS generate and assign an IP address if the computer cannot reach a DHCP server.These autogenerated addresses are in the range of 169.254.x.x. If your IP address is in 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 183. •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 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. Troubleshooting 176 Nighthawk X4S AC2600 Smart WiFi Router
You 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 ADVANCED Home page. To check the WAN IP address: 1.Launch a web browser from a computer or WiFi device that is connected to the network. 2.Select an external site such as netgear.com. 3.Type http://www.routerlogin.net. A login window opens. 4.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 page displays. 5.Click the ADVANCED tab. The ADVANCED Home page displays. 6.Check to see 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 174. 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 on the Internet Setup page. •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 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 obtained an IP address, but your computer does not load any web pages from the Internet, it might be for one or more of the following reasons: •Your computer might not recognize any DNS server addresses. Troubleshooting 177 Nighthawk X4S AC2600 Smart WiFi Router
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 Never dial a connection. Other browsers provide similar options. Troubleshoot Internet Browsing If your router can obtain an IP address but your computer is unable to load any web pages from the Internet, it might be for the following reasons: •The traffic meter is enabled, and the limit was reached. By configuring the traffic meter not to block Internet access when the traffic limit is reached, you can resume Internet access. If your ISP sets a usage limit, they might charge you for the overage. •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. Other browsers provide similar options. Changes Are Not Saved If the router does not save the changes that you make on the router web pages, do the following: •When entering configuration settings, always click the Apply button before moving to another page or tab, or your changes are lost. •Click the Refresh or Reload button in the web browser. It is possible that the changes occurred, but the old settings might be in the web browser’s cache. Troubleshooting 178 Nighthawk X4S AC2600 Smart WiFi Router
Troubleshoot WiFi Connectivity If you are experiencing trouble connecting over WiFi to the router, try to isolate the problem: •Does the WiFi device or computer that you are using find your WiFi 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 routerWiFi radios back on. If you disabled the router’s SSID broadcast, then your WiFi network is hidden and does not display in your WiFi client’s scanning list. (By default, SSID broadcast is enabled.) •Does your WiFi device support the security that you are using for your WiFi network (WPA or WPA2)? •If you want to view the WiFi 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. Be sure to click the Apply button if you change settings.Note If your WiFi 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 WiFi 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. 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 the Start button 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 see a message like this one: Pingingwith32bytesofdata If the path is working, you see this message: Troubleshooting 179 Nighthawk X4S AC2600 Smart WiFi Router
Replyfrom:bytes=32time=NNmsTTL=xxx If the path is not working, you see this message: Requesttimedout If the path is not functioning correctly, one of the following problems might be occuring: •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 to see 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 To 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 Windows Run window, type ping -n 10 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 179. 3.If you do not receive replies, check the following: •Check to see that IP address of your router is listed as the default gateway for your computer. 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 to see 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 on the Internet Setup page. •Your ISP might be rejecting the Ethernet MAC addresses of all but one of your computers.
