Solution to the problem of wireless router's inability to access the Internet

In the days when wired network is ubiquitous, the "figure" of WLAN is moving closer and nearer to us, which is very much in step with the wired network. Considering the current wireless LAN is through the wireless router to network, wireless LAN can be efficient Internet and wireless router status closely related; Unfortunately, wireless routers in the long hours, often appear a variety of "strike" phenomenon, if not in time to exclude these phenomena, Then the network efficiency of WLAN will be affected obviously. In view of this, this article will be a frequent occurrence of wireless routers summed up the phenomenon, and each one of the mysteries of the puzzle!

FAQ No Line by the mystery of the inability to dial automatically

When using a wireless router for broadband dial-up access, we may often encounter the device can not automatically dial the strange phenomenon, encountered this phenomenon, we can from the following aspects of the investigation:

First confirm that the wireless router you use is the local telecommunications department's network license, if the device does not have access to the Telecommunications network license, then the wireless router through the local telecommunications department provided by the line for dial-up operation, it is easy to automatically dial the phenomenon. For example, a wireless router may be normal in the south, but it may not be normal after the north, in order to solve this incompatibility, the general need for the wireless router within the relevant firmware for special upgrades to ensure that the wireless router dial normal. At present, the introduction of the market of wireless routers, broadband routers are not compatible with the local telecommunications department ADSL network line equipment, even if these products can be compatible with dial-up, but in the regular use of the process is also prone to dial-up disconnection and other failures. In fact, we can use the ADSL equipment of the local telecommunication Department to dial the Internet, after all, these devices have the PPPoE dial-up function, which is almost always recognized by the local telecommunication department. Using the PPPoE dial-up feature from the ADSL client can ensure that dial-up Internet access is both stable and fast.

Second, check the wireless router for the correct parameter settings, especially to see if the MTU value is set correctly. When dial-up information is transmitted on the network line, it is often automatically segmented into different sizes of data packets, and the MTU value parameter is used to specify the packet size standard. When the MTU value is set larger, it means that the data packet size is larger, theoretically can also achieve the purpose of increasing the transmission rate, but we can not arbitrarily set the MTU is too large, after all, the data packet is too large, dial-up information in the transmission is very easy to error, especially with the telecommunications Department of the local equipment parameters do not match. Normally, we can set the MTU value to the maximum of 1492 when using the PPPoE dial-up connection, and try to set the maximum value of the MTU value to 1500 if you are surfing the Internet over the LAN mode. Therefore, when the wireless router is not able to automatically dial the phenomenon, we can enter the background of the device to set up the interface, check the device's MTU value is 1492, if found wrong, must be in time to modify it.

Let's see if the ADSL Client access device is working the right way. In general, ADSL access equipment mainly includes ADSL modem and ADSL router two types, of which ADSL modem equipment only support bridge working mode, and ADSL router can support bridge working mode and routing work. ADSL Router equipment is currently widely used broadband Internet access equipment, it supports PPPoE, RFC-1483 Bridge, PPPoA, Enet EnCap, such as data packaging, if we use ADSL router equipment and wireless router equipment to network, Then we have to let the dial-up line through the ADSL router device and then connected to the wireless router, and then by the wireless router for PPPoE dial-up operation; and we have to first of all the ADSL router equipment to adjust the mode of operation of RFC 1483 bridge bridging Way, Before you can connect to the wireless router, and finally log on to the wireless router's background management window, set up the network access mode through the Parameter Setting Wizard function, when setting up the access mode, you must select the ADSL PPPoE dialing method, at the same time, the ISP service provider's account information and Vpi/vci parameters are correctly set , I believe that through the above efforts, wireless routers can not automatically dial the phenomenon of failure must be able to exclude.

FAQ No Line by unable to login setup mystery

To make the wireless router work efficiently, we often need to set it properly. However, when we try to log on to the wireless router's Web Administration page, we often encounter failures that fail to log on when we set the parameters for wireless Internet access. Facing this kind of malfunction phenomenon, how should we solve it?

Causes this phenomenon mainly has two aspects, one aspect is because of the line connection or the wireless router and so on hardware factor to have the fault, another aspect is the wireless router or ie browser parameter setting is improper. But the hardware fault mainly includes the network connection cable to appear the circuit breaker phenomenon, the network connection joint appears loose phenomenon, the computer system operation unusual phenomenon as well as the hub or the router and so on relay equipment damage phenomenon, this aspect's fault usually can by observes the wireless router signal light method to help determine; Of course, the input voltage is not normal, Equipment internal temperature is too high, or equipment encountered lightning, etc. also easily cause hardware failure.

When you look at the data semaphore in the wireless router Control Panel, if we find that the signal light intermittent flashing that means that the line connection is normal, once found that the signal is not working properly, you must first check whether the broadband line connectors are in contact with a solid, internal core line is in short circuit or disconnected state, in the conduct of this inspection, We can test with other cables that are connected to normal. After the cable factor is excluded, we need to go to the workstation to check the wireless network connection settings, such as we can reset the Workstation network card IP address, if found in the automatic access to the IP address state can not log on to the wireless router, you may consider using a static IP address at the same time disable the workstation system used by the firewall.

If the above exclusion method is still invalid, we also need to open the workstation system's IE browser to see if the program's connection settings are correct. When doing this check, we can open the IE browser window first, click Tools/Internet Options in the menu bar of the window, click the Connection tab in the pop-up Internet Options Settings window, and in the corresponding tab page, "Never dial connections." The item is selected (as shown in Figure 1) and the OK button is clicked. After that, click the LAN Settings button, and then empty all the setup options in the Settings window, and then click the OK button, and try to open IE to enter a no circuit address for the login connection.

Figure 1

If this solution does not solve the problem, the only thing we can do is to restore the parameters of the wireless router to the factory default settings, and reinstall the corresponding device driver, if not even this method is not possible, then we can almost determine the wireless router itself has a hardware failure, At this time only please professional and technical personnel to solve the door.

The mystery of not being able to stabilize the job without a line

When broadband dial-up Internet access through the wireless router, it is common to encounter the phenomenon that the Internet often falls off the line. This phenomenon, in addition to our access to the network content, but also with the network virus attacks and wireless router parameter settings, to avoid this phenomenon, we can follow the steps to do the following:

First go to the wireless router's background management interface, check the device connection is set up correctly. Considering that ordinary wireless routers tend to support more than three connections, and in the default state most wireless routers will work on the "on-demand connection, when there is access to the content of the automatic connection" This setting state, in other words, it will periodically detect the dial-up line is not in no-load state, If the broadband dial is successful, there is no data transfer interaction on the line, the wireless router will automatically disconnect the currently established connection, so when we find that the wireless router is working on an on-demand connection, automatically connect when there is access mode, you must log on to the wireless Router Background Settings window and in the connection mode setting Automatic connection, automatic connection after power-on and disconnection "item selected, finally save the set parameters and restart the wireless router.

If the wireless router is still unable to stabilize the operation after the above setup, then we need to check if there is a network virus at work. In the case of a virus check, we can use the latest version of anti-virus software, the workstation system of each "corner" for a thorough killing; after killing the virus, you need to go to the workstation's TCP/IP parameter settings interface, and in the interface to try to swap with another IP address (as shown in Figure 2), This is an effective way to avoid ARP network attacks. If the wireless router continues to drop the line, then we need to use a professional defense program to protect the wireless router.

Of course, if we are only accessing specific network content, the wireless router will often fall off the phenomenon, which is mostly caused by the network content itself, at this time we can try to access other network content to confirm whether the wireless router is not working properly.
