The severity of the router drop problem believe that the user experience the most profound, and they have made a lot of planning strategies. The following will introduce you to the router drop the problem of the solution, I would like to refer to you.

Router drop is probably not its own cause, before blaming routing, you need to verify that your network environment is normal. will be a computer directly through the cat or community broadband mouth, at this time if not to the Internet can not call the words are generally telephone line insulation or bad contact, we can carefully check the line will have damaged the place with insulation tape or directly reported to the operator to request on-site repair. If you can not call the Internet may be the Internet line problem, cat problem or network cable problem. Show "remote computer does not respond" means Internet line problem, eliminate this possibility after you can try to change the cat, network cable.

In addition to the problems with these devices, voltage instability can also be a router does not work as a killer. We recommend that you do not let the route, cat equipment and induction cooker, air-conditioning, washing machines, refrigerators, televisions share a board, so as not to cause unnecessary damage. Of course, it is also necessary to place the router in a cool, dry area.

Eliminate the hardware environment problem, we look at the software may cause the router to drop the problem analysis.

1, to ensure that the intranet address and external address does not conflict

This problem is often encountered when using community broadband Internet. Before surfing the internet, we need to view the instructions to understand the router's default administrative address. For example, your ISP's IP is 192.168.1.*, and your router's default management address is 192.168.1.1. At this point you need to do is not connected to the Internet directly with the computer landing router will be the default address to 10.1.1.1 or 172.16.1.1 and other unused to the reserved IP address. If you do not know your own IP, right-click the computer screen in the taskbar in the tray area of the "Network Connection" icon, select "Status", in the Open submenu select the "Support" tab, you can see.

2. Ensure that there are no excessive DHCP servers in the network

If you have a Windows 2000/NT server on your network or if your ADSL cat has DHCP server capabilities, you can turn off all DHCP servers in your network, use manual IP addresses, or leave only one DHCP server.

3. Ensure DNS settings are correct

QQ can not open the Web page this kind of pseudo-drop the most of the situation because the DNS settings are not caused. We recommend that you set up the DNS server address manually on the router and computer network card. In addition, the DHCP service settings item in the router management interface also requires you to manually set the DNS server address. The address needs to be obtained from the ISP's provider, and you can search for a DNS network of your own region if you are not able to find it.

4, the computer MAC address cloned to the router WAN port

Some ISPs bind MAC addresses on the authentication server in order to limit the number of access users. In this way, there will be a phenomenon in our network where other computers can be disconnected. We'd better fix the problem by configuring the router for the first time. If the router has MAC address cloning, we can first connect the computer that is bound to the MAC address to the router LAN port, and then use the MAC address cloning function to copy the MAC address of the network card to the WAN port of the broadband router. If the router does not support this feature, we can also modify the MAC address of the WAN port directly at the time of configuration.

5, do not save the record or regularly clean up the record file

Routers are now almost all with logging, but writing logs is a resource-intensive, and home-routed memory and Flash are inherently small. We recommend that the user be set to not save the record or to clean the record file frequently (once a week is recommended).

6. Upgrade Firmware

Manufacturers to provide upgrade firmware for users to better use the router, we follow the manufacturer's requirements to upgrade without worrying about the warranty issue. In the event of a problem, the router has a reset button, which, depending on the instructions, holds down the button for a few seconds to restore the default configuration, and the username and password for the logged-on Web are restored to their original values. If you cannot use it, you can find it after sale.

If you do the above, I believe that the router will not be so frequent off the line.

Router off the line also may be because the amount of data is too large, because the amount of data caused by BT, donkey and so on, we can solve through internal control, and because the computer and routers are black caused by the amount of data is too large to need security experts. In fact, the router is our computer security outpost, to prevent it from being black is also significant to us. If you have enough expertise or can find network management to help, we recommend that you take the following measures:

1, modify the router password

Common passwords, such as the default password or "123456", are dangerous, and we recommend that you modify the password by adding a letter with a number plus a special symbol. In fact, the simplest thing is to replace one letter of a word with a number, such as "L0ve" (O is replaced with the number 0). What do you think of it?

2. Disable Remote Web settings, disable ICMP requests from external SNMP connections, Telnet connections, and Ping

If your router supports Telnet or SSH, you might want to disable remote Web settings. ICMP requests from external SNMP connections, Telnet connections, and Ping are also common ways for hackers to turn off comparison insurance. For these internal connections you can not disable but record mail to your mailbox, you can find out the intranet of the "Black Sheep."

3, turn on packet filtering, disable IP directed broadcast

Packet filtering is to allow only some ports of the child machine to connect outside, and many companies only allow 80 ports (HTTP) and 110/25 ports (receive/Send e-mail). Disabling IP directed broadcasts can prevent DDoS attacks.

4, if you open the log, please give way by sending mail to network management

A lot of the information in the log records will remind the webmaster what needs to be done and whether there has been a fuss. The sooner a network administrator understands the situation, the easier it is to solve the problem.

Router drop-line problem seriously affect our network life, in order to prevent it, please readers to do a little more now, you may avoid the future of the big trouble. We believe that as long as you seriously treat your baby route, it will certainly not let you down.
