Broadband router applications are very common among SOHO and small and medium business users. For some newcomers to the network, there are some faults that are not covered in the manual, and sometimes it is difficult to cope. Below, analyze some common faults and problems and provide solutions. First, the line is unreachable, unable to establish a connection 1. Connect the WAN port of the router to the ADSL Modem with a network cable, and the telephone line is connected to the “Line” of the ADSL Modem. A straight-through line should be used for the connection between the ADSL Modem and the Broadband Router. 2. Check if the Link light signal in the router LAN is displayed and whether the router to LAN is online. The router's LAN port can be connected either directly to the computer or to the switch. Second, the network settings are incorrect. Check the manual to find the default management address of the router. For example, the default IP address of the router is 192.168.1.1 and the mask is 255.255.255.0. Please connect your computer to the LAN port of the router. You can use two methods. The computer sets the IP address. 1. Set the IP address manually. Set your computer's IP address to 192.168.1.xxx (where xxx is 2 to 254), the subnet mask to 255.255.255.0, and the default gateway to 192.168.1.1. When using the cell broadband access mode, you should ensure that the internal IP address assigned by DHCP is on a different network segment than the IP address used by the cell. 2. Use the built-in DHCP server of the router to automatically set the IP address. 1) Set your computer's TCP/IP protocol to “Obtain an IP address automatically” and “automatically obtain the DNS server address”. 2) Turn off the router and your computer. First turn on the router and then start your computer. 3. Unable to dial ADSL Open the web browser and enter the management address of the router in the address bar, for example, 192.168.1.1. At this time, the system will ask for the login password. This password can be found in the product manual. Go to the management interface and select the menu “Network Parameters” under “Network Parameters”. In the main window on the right, “When the WAN port connection type” is selected, select “PPPoE” and enter “<quo;Internet account”” and “Internet password”, click the connect button. 4. The ISP is bound to the MAC address and cannot be connected. Some broadband providers bind the MAC address on the authentication server in order to limit the number of access users. In this case, you can first connect the computer with the MAC address bound to the LAN port of the router (but the router should not connect to the modem or the wiring provided by the ISP), and then use the MAC address cloning function of the router to copy the MAC address of the NIC to the broadband. The WAN port of the router. Under Windows 2000/XP, press “Start →Run”, enter “cmd/k ipconfig /all”, where “Physical Address” is the local MAC address. 5. After the Internet accesses for a period of time, it will be dropped. After the router is turned off, it can be connected again. 1) Excessive DHCP servers in the network cause IP address confusion. You need to shut down all DHCP servers on the network, manually assign IP addresses or leave only one DHCP server. These DHCP servers may exist in Windows 2000/NT servers, ADSL routers, and ADSL Modems. 2) This type of router is not compatible with the ISP's central office equipment. This type of problem can only be replaced by other models of routers or ADSL Modem. 3) The router and ADSL equipment are not well cooled. If it is normal when the Internet is online, after a while, the network speed will drop. If the device is hot by hand, the speed of changing the device will be normal, indicating that the cooling environment is not good. 4) Check all connected computers for worms or Trojans. Please use the anti-virus tool and Trojan killer to scan for viruses or Trojans on your computer and then connect to the network. 6. Why does the network fee far exceed the estimated cost? If it is a non-monthly user, you can choose ““connect as needed” or “manually connect” and enter the automatic disconnection waiting time to prevent forgetting the disconnection and always be connected and wasting time online. . If you use the time-based tariff standard, you should set the router to “on-demand connection” and also set the waiting time for automatic disconnection. That is, when there is no Internet access request within the specified time, the router can automatically cut off ADSL. connection. Why is there a phenomenon that can use QQ and play games, but can't open the webpage? This situation is a DNS resolution problem. It is recommended to manually set the DNS server address (the address provided by the ISP) on the router and computer network card. In addition, in the "DHCP Service" setting item, the DNS server address is also manually set, which needs to be obtained from the ISP provider. 8. Forgot the password for logging in to the router management page. Some router devices have a Reset button. Press and hold this button for a few seconds to restore the default configuration. The user name and password for logging in to the Web are restored to their initial values.
