This article will give you a glimpse on the basic process on how to troubleshoot internet connection for Windows XP computer. It provides frequent internet connection problems and the know how to repair it. This will discuss different ways to diagnose and determine the problem(s) in any of the following: internet browser, Telnet and FTP (file transfer protocol).

It assumes that you can connect and logon to your ISP server. Any problem with your ISP connection will not resolve in this article.

Here are the common reasons that stop your computer from connecting to the internet:
• You have typed the wrong web address
• The server you are trying to open is no longer existing or temporarily unavailable
• Your internet browser is not configured properly
• The TCP/IP of your ISP (Internet Service Provider) is not properly configured
• Corrupted or damaged host files in your system driver

Now, let us discuss each reason and know hoe to resolve it.

Usually when you typed a wrong or misspelled web address your browser will display an error notice. If this happened, you have to do is to double check the spelling and do the necessary corrections.

There are instances that you spelled and typed the correct address and an error will be displayed on your screen. If this happen, you are trying to connect to a web server or site that is no longer available or temporarily out of service. To verify try to open at least two other web sites. If those sites open, then you can conclude that the web site is not available.

If you cannot connect to any web site, you might have problem with your internet browser or TCP/IP configuration. Make sure that your internet browser is properly configured based on your ISPs configuration so you could connect to the internet. Make sure your browser is not configured to connect to a proxy server. To check the configuration of your internet browser, follow these steps. First, open your browser. Next, on the menu bar click on TOOLS>INTERNET OPTIONS. Third, select the CONNECTION TAB and select ISPs settings. If you are connected to a network, select LAN settings.

The next thing that you have to verify is your TCP/IP configuration. Most of the ISP provides static IP address. Make sure that your configuration contains the correct information. To check your settings, follow these steps:

  1. Connect to your ISP
  2. Open a command prompt. Make sure you are in drive C.
  3. Type the command: ipconfig/all and press ENTER key from your keyboard
  4. The Windows TCP/IP settings for all your network adapters, modem, Bluetooth and wireless adapter will be displayed on your screen.
  5. Verify if the IP configured match with the IP from your ISP. If not, changed the IP. To do this, follow the steps below:
    a. Go to Control panel and select Network Connections
    b. Right click on your internet connection and select Properties.
    c. Click Networking Tab
    d. Click
    Internet Protocol Adapter, then click Properties button
    e. Check if the given settings is the same with the one provided by your ISP. If not, change the settings to what was provided to you and click OK when done. Click OK again.

Check the light buttons of your network card and modem

If you are connected to a local network through your network card/adapter, and your hub or router is connected to the modem of your ISP, there might be a conflict between your network adapter and your modem.

First, check the send and receive light of your network card and the connection from your hub or router. Then verify if the TCP/IP are being routed through your modem. Open a command prompt, type the command ping IP address and press Enter. It should give you a response. If none, like request time out there is an error with your network connection or modem or your network adapter. Try to ping any PC's IP address, if there will be no reply, then your network card is not functioning.

Now, let us isolate the problem. If you are connected to a local network, try to ping other pc's IP address. If you were able to receive a reply, then your network connection is ok. Try to ping any website like www.yahoo.com, if it said request time out then there might be problem with your modem. But if you received a response and still cannot browse, you have to contact your ISP's technical support.

If in case you are working on a stand alone pc, try to ping a website then follow the procedure as what I mentioned before.
