I believe that many Internet users will "deal" with broadband routers directly or indirectly, but in the process of using broadband routers for a long time, people rarely look at it. Even when there are various access failures in the network, people rarely think that network failures are related to broadband routers! In fact, broadband routers are like other ordinary network connection devices. Once we set up improperly or maintain them properly, they are prone to various inexplicable failures, which will directly affect our daily network efficiency. In order to effectively improve the efficiency of the Internet, this article focuses on wideband routing and provides you with some experience and skills in managing and maintaining broadband routers. I hope these contents can be useful to everyone!
Correct connection to ensure smooth lines
To make a broadband router work, you must first ensure that the network line connected to it is in a smooth state. To keep the line unobstructed, the first thing you need to do is to correctly connect the broadband router to the network. Under normal circumstances, we should use twisted-pair cables to connect the WAN port in the broadband router control panel with the ADSL Modem, and the telephone cable must be inserted into the "Line" port of the broadband cat. It is also necessary to remind everyone that the twisted-pair cable connecting the broadband router and the broadband cat must use a straight-through cable. After connecting the broadband router to the network according to the above method, the Link signal light corresponding to the LAN port in the router control panel should be in a long-lasting state or blinking state. If the signal light is not normal, it means that there is a problem with the line connection between the broadband router and the LAN network. At this time, the connection line must be re-checked.
Set up an account to ensure the dialing is successful
In the actual process of using broadband routers, we often encounter the phenomenon that we cannot successfully perform ADSL dialing. When encountering this phenomenon, we mostly do not set the automatic dialing parameters of the broadband router correctly. At this time, we might as well follow the following steps to re-set the dialing parameters of the broadband router:
First run the IE browser program, and then directly enter the IP address of the broadband router in the address bar of the IE browser window. This address can usually be found in the broadband router's operating manual. The address is generally 192.168.1.1 under the default state. After confirming that the IP address is entered correctly, click the Enter key, and an account login window will automatically pop up in the IE browsing window. Enter the account password correctly in this window (this password information can also be found in the broadband router's operating manual). After that, you can successfully enter the management window of the broadband router. Click the "Network Parameters"/"WAN Port Settings" command in the menu bar of the window. In the display pane on the right side of the interface, find the "WAN Port Connection Type" setting option, and then set the option parameter to "PPPoE". At the same time, correctly enter the username and password information for dialing up online. Finally, save the above settings parameters, and then restart the broadband router. This will ensure that the broadband router automatically dials successfully.
Check DNS and open the web page correctly
When dialing up through a broadband router, we sometimes encounter strange phenomena that we can use QQ but cannot open web pages. This failure is usually caused by incorrect domain name resolution. We must re-check the DNS parameters of the broadband router.
When checking whether the DNS parameters are correct, you also need to run the IE browser program first, and then directly enter the IP address of the broadband router in the address bar of the IE browser window. After clicking the Enter key, you can correctly enter the account password in the account login window. Then you can successfully enter the management window of the broadband router. Click the "Network Parameters"/"DNS Service" command in the menu bar of the window, and in the settings interface that appears afterwards, check whether the DNS parameters are set correctly. Generally speaking, we should use the DNS server IP address provided by the local ISP, instead of using the router's default DNS server IP address. After the DNS parameters are modified correctly, perform a save operation, save the above modification settings, and restart the broadband router device. I believe this will solve the problem of the web page being unable to open. Of course, if we still use QQ and cannot access the Internet through the above efforts, we also need to enter the local connection attribute setting window in the local computer system, select the "Internet Protocol" parameter, then click the "Properties" button, and then in the attribute setting interface of the Internet protocol, change the DNS server address used by the local network card to the DNS server IP address provided by the local ISP, so that the failure of web pages cannot be opened can be completely solved.
Modify the address to ensure the correct settings
As we all know, if the IP address of the workstation is not on the same network segment as the IP address used by the broadband router, it may lead to the inability to successfully access the web page content. How can we ensure that the IP address of the workstation is on the same network segment as the IP address used by the broadband router? To achieve this, there are two ways to achieve it:
The first method is to first check what the default IP address is used by the broadband router, and then manually modify the network card parameters of the workstation to ensure that the network card address is in the same network segment as the address of the broadband router. For example, if the IP address used by a broadband router is 192.168.1.1 and the mask address is 255.255.255.0, then we can open the local connection attribute setting window in the local computer system, select the "Internet Protocol" parameter, then click the "Properties" button, and then change the IP address of the network card to 192.168. in the attribute setting interface of the Internet protocol, where the "xxx" range is from 2 to 254. At the same time, the subnet mask address of the network card is set to 255.255.255.0, and the default gateway address used by the network card is set to 192.168.1.1. This can ensure that the workstation IP address is in the same network segment as the IP address used by the broadband router.
The second method is to enable the built-in DHCP service of the broadband router to automatically assign IP addresses to the workstation. When using this method, we first run the IE browser program, and then directly enter the IP address of the broadband router in the address bar of the IE browser window. After clicking the Enter key, we correctly enter the account password in the account login window. After that, we can successfully enter the management window of the broadband router. Click the "Network Parameters"/"DHCP Service" command in the menu bar of the window, and set the parameters of the DHCP service in the settings interface that appears afterwards. Next, open the local connection attribute settings window in the local computer system, select the "Internet Protocol" parameter, then click the "Properties" button, and then set the IP address of the network card to "Automatically obtain IP address", and set the DNS parameter to "Automatically obtain DNS server address". After completing the above settings, turn off the workstation power supply and the broadband router. Then, connect the power supply of the broadband router first, and wait until the broadband router is stable, then connect the power supply of the computer. This will ensure that the workstation successfully dials up and access the Internet through the broadband router.
Unbind and restore normal connection
At present, in order to prevent users from connecting too many workstations to broadband routers to achieve shared Internet access, many ISP service providers often forcefully bind the MAC address of the broadband router on the authentication server to limit the number of workstations access. When encountering this situation, we can cancel the binding of the broadband router to the MAC address according to the following method:
First, disconnect the wiring of the broadband router from the Internet connection, and then connect the workstation with the MAC address to be bound to the LAN port of the broadband router. Then, through the broadband router's own MAC address copy function, clone the MAC address of the local workstation network card to the WAN port of the broadband router device, and finally restart the broadband router device. In this way, we can cancel the default address binding of the broadband router.
Borrow Reset to retrieve lost password
If many people do not manage and maintain broadband routers for a long time, it is easy to forget their administrator account and password. If we do not have the operating manual of the broadband router, it will be difficult for us to enter the backend management page of the broadband router to manage and maintain it. When encountering this situation, how should we retrieve the lost administrator password? In fact, some broadband router manufacturers have already considered this problem for users. They often have designed a Reset button in the broadband router control panel. After pressing and holding the button for a few seconds, all parameters of the device can be restored to the factory configuration. In the future, as long as we use the default username and password, we can log in to the background management page of the broadband router again.
Check one by one to ensure stable Internet access
When using a broadband router to access the Internet, it is often possible to have stable Internet access, such as frequent disconnection and inability to access for a long time, and in severe cases, you will not be able to access the Internet. When encountering this kind of unstable Internet access, we might as well follow the following steps to check it item by item:
First, check whether there are multiple DHCP servers in the LAN environment connected to the broadband router. If they exist, the IP address of the workstation will easily become confused, which will easily lead to unstable Internet access in the workstation or even unable to access the Internet. Generally speaking, devices such as broadband routers, Windows servers, and broadband cats may enable DHCP servers. For this reason, we need to check these devices one by one to ensure that only one of these devices enables DHCP services, and the rest must disable DHCP services.
Next, check whether the broadband router is in a well-ventilated and heat-dissipated position around it. If it is placed in a poor position, it is easy to cause excessive heat after working for a period of time, and in severe cases, it can cause unstable Internet failures. Therefore, when we unfortunately encounter unstable Internet access failure, we must touch with our hands whether the outer shell of the broadband router is hot. If so, we can basically determine that the unstable Internet access failure is caused by unstable heat dissipation of the broadband router.
If the above checks cannot eliminate unstable Internet access faults, then it is necessary to conduct virus detection and killing of the workstation system connected to the broadband router, because once the workstation system is accidentally infected with the virus, all kinds of strange faults may occur. Therefore, we must develop the good habit of regularly checking and killing viruses and regularly upgrading the virus database to prevent online viruses from causing trouble to the Internet.
Correct connection to ensure smooth lines
To make a broadband router work, you must first ensure that the network line connected to it is in a smooth state. To keep the line unobstructed, the first thing you need to do is to correctly connect the broadband router to the network.
