One of the most common problems among internet users is testing their
Internet to identify the problem. There are a large number of Internet users who use DSL and cable modem services.
Set your connection, like your ISP (Internet Service Provider), a commission. Sometimes it works, for many reasons.
Their service is not ready, the hardware is connected properly, or problems with your ISP.
Regardless of the cause ofProblem, perhaps, there are some diagnostic tools you can use in Windows XP to identify the problem.
If you are not exactly in the diagnosis, there will be a good idea, anyway.
Before coming to the diagnostic tools that allow us to discuss what is involved in a connection to the Internet.
The information travels over the Internet to your computer via the service provider of Internet services. This will be installed by a high-speed modem has a network card in your computer has.
YourComputer called the host, give your service
The IP address of DNS server, and you will receive your login and password. This is everything you want from your ISP.
Sometimes, the Internet connection fails, and if you want to find
problem. You can solve the problem, or at least get a little '
About the problem, consult your ISP for help.
We begin with access to the command prompt, then clicking on:
Start Menu, Programs,Accessories, then Command Prompt. Window
when you open the command at the command prompt.
At the command prompt, command prompt, type: IPCONFIG. This command gives you the active network connection on your computer. Here's an example:
PPP adapter Copy:
Connection-specific DNS Suffix. :
IP address. . . . . . . . . . . . : 68.239.158.45
Subnet Mask. . . . . . . . . . . : 255.255.255.255
Default Gateway. . . . . . . . . : 68.239.158.45
TheThis edition was created when I run the ipconfig command on my computer running Windows XP and a DSL connection. The IP address of my computer from the address assigned by your ISP.
Please note, you can create an option to add this command to get detailed information about the connection. The output when I ran the same command with the
Option "All".
Ipconfig / all
PPP adapter Copy:
Connection-specific DNS Suffix. :
Description. .. . . . . . . . . : WAN (PPP / SLIP) Interface
Physical Address. . . . . . . . . : 00-53-45-00-00-00
DHCP enabled. . . . . . . . . . . : No
IP address. . . . . . . . . . . . : 68.239.158.45
Subnet Mask. . . . . . . . . . . : 255.255.255.255
Default Gateway. . . . . . . . . : 68.239.158.45
DNS server. . . . . . . . . . . : 151.198.0.39
151.197.0.39
NetBIOS over TCP / IP. . . . . . . . : Disabled
Note now that the output includes thePhysical address of the network interface card installed in my computer. In addition, you will see the DNS IP addresses. With the information above, I have no problems.
Should I keep my DSL connection and ran the command again, this is the new record:
Ethernet LAN:
Connection-specific DNS Suffix. :
IP address. . . . . . . . . . . . : 192.168.0.1
Subnet Mask. . . . . . . . . . . : 255.255.255.0
Default Gateway. . . . . .. . . :
Note: In this case, when I disconnected my connection, do not get a DNS server. This shows that I'm not connected to the Internet.
Also note the IP address starts with 192.168, the address of default, if your computer is not connected to the Internet.
Another command is the ping command. Examine to determine if a computer is connected to the network and wish to communicate, whether intranet,
or the Internet.
Once you start, youa packet to the computer specified and gives the travel time to the package. This is a one-out, when I tried to ping http://www.yahoo.com:
C:> ping http://www.yahoo.com
Ping Www.yahoo.akadns.net [216.109.118.66] with 32 bytes of data:
Reply from 216.109.118.66: bytes = 32 time = 35 ms TTL = 55
Reply from 216.109.118.66: bytes = 32 time = 39MS TTL = 55
Ping statistics for 216.109.118.66:
Packets: Sent = 4, Received = 4, Lost = 0 (0%Loss)
Approximate round trip times in milliseconds:
Minimum = 35ms, Maximum = 39MS, Average = 38ms.
This shows that the host could be achieved, and connected to the Internet.
A command is very important Nslookup. So that you can verify that DNS (Domain Name Server) correct. The function of the DNS server IP addresses of domain names of computers on the network to translate. Here's an example:
C:> nslookup http://www.yahoo.com
Serverhome5.bellatlantic.net
Address: 151.198.0.39
Non-authoritative answer:
Name: http://www.yahoo.akadns.net
Addresses: 216.109.118.67
Alias: http://www.yahoo.com
Then, enter the name Nslookup, enter IP addresses and vice versa.
In summary, there are several commands in Windows XP, with the three above commands, but it should be a good idea for problems with your Internet connection. You can find where the problem occurs. IsYour car or Internet service provider.
