Broadband routers in the use of the process often occurs, and the virus is the most common broadband router fault, the following will be specific to solve the problem of broadband router troubleshooting.
One, the virus causes the router overload
This is why the broadband router fault occurs in the topological structure is this: the use of a EnterasysSSR8000 as a border router, but also with it to divide the campus into 8 virtual nets, each virtual network has a stacked two-layer switch as a desktop and notebook access equipment, the backbone of the thousand trillion, Hundred megabytes to the desktop.
Specific fault: The machine can not be connected to the Internet, the virtual network and Network Center is not in the same virtual network. The machine system is Windows XP, has not recently installed any new program, has not moved the computer, also did not pull out the network cable.
Second, broadband router fault resolution
(1) First troubleshoot the network client's error configuration. Enter Msdos mode to check the IP address configuration of the host using the ipconfig command:
C:>ipconfig
Windows IP Configuration
Ethernet Adapter Local Area Connection:
Connection-specific DNS Suffix. :
IP address. ...........:210.16.2.30
Subnet Mask ........... : 255.255.255.0
Default Gateway ..... . 210.16.2.1

(2) The configuration shown above is correct, and then ping your own IP address:
C:> Ping 210.16.2.30
Reply from 210.16.2.30:bytes=32 time<1ms ttl=128
Reply from 210.16.2.30:bytes=32 time<1ms ttl=128
(3) This means that the IP address is in effect, the network card works properly, and then use the ping command to test the connection from the local to the gateway:
C:> Ping 210.16.2.1–t
Reply from 210.16.2.1:bytes=32 time<1ms ttl=128
Reply from 210.16.2.1:bytes=32 time<1ms ttl=128
......
(4) packets sent from the host to the gateway, all received a response, the line is connected. Open the browser, also can be normal Internet, a little bit of a problem.
(5) The probability of two unrelated hosts having the same problem at the same time is almost zero. In view of this, the failure of the connecting cable is eliminated first, because the connection cable is not likely to have such a intermittent delay, the broadband router failure is most probably the other end of the line cable-two-tier switch.
(5) View the status of the switch, which is a stack of two switches, one of which has a gigabit port on top.
Third, the summary of the problem
After troubleshooting the software issue, finally check the hardware. In the above steps to determine a certain aspect of the broadband router failure, if it is found that the hardware broadband router failure, you need to remove the hardware parts replacement. However, this process generally does not require your hands-on, often the supplier or manufacturer of the engineer to implement. If the longer the time, it will exceed the product repair, shifting time limit, it is not worth the candle.
For many users who use broadband routers, often encounter broadband router failures, encounter their own powerless broadband router failure, in addition to relying on their own experience, product brochures, manufacturers outside the site, to quickly think of your product suppliers, and contact with to help solve the problem quickly.
