  4. If youre connecting to a secure network, type the security key, and then click OK.
  
  

  Check hardware in Windows XP

  Many network connection problems are caused by hardware that isnt set up properly. Heres some information about how to check your cables, check or reset your modem, and check for problems with your network adapter.

  Make sure your hardware is compatible with Windows

  For a list of compatible hardware, visit the Compatibility Center:

  • The Latest Windows XP Hardware Compatibility List

  Check the wireless switch (wireless networks only)

  If you’re using a laptop, make sure that the network adapter switch on your laptop is turned on. Many laptops have a physical switch somewhere on the top, front, or side of the laptop that turns the network adapter on or off. Theres usually an indicator light on the laptop that shows if the wireless network adapter is enabled.

  Make sure all cables are connected properly

  Loose or disconnected Ethernet cables, DSL or cable connections, telephone cords, USB cables, or power cables can cause network or Internet connection issues. Check all of these connections to make sure they are properly connected. This section mainly applies to wired networks, but if youre trying to connect wirelessly to your own home wireless network, you should check the modem and cabling to the modem as described below.

  To check DSL Internet connections

  1. Check the phone line that runs from your phone jack to the phone line port on the DSL modem.
  2. Make sure theres no DSL filter between the phone jack and the modem.
  3. Check the Ethernet cable that runs from the Internet connection on the DSL modem to the network adapter on your computer.
  4. Make sure the DSL modem is plugged into a power outlet and the power to the modem is turned on.
  5. To avoid dropped Internet connections, make sure all telephones that are connected to the same line as the DSL modem are connected to a DSL telephone phone line filter.

  To check cable Internet connections

  1. Check the coaxial cable that runs from the wall to your cable modem.
  2. Check the Ethernet cable that runs from the cable modem to the network adapter on your computer.
  3. Make sure that the modem is plugged into a power outlet and the power to the modem is turned on.

  To check dial-up Internet connections

  1. Check the telephone line that runs from your telephone jack to the telephone port on your computers modem to make sure the connections are good and the phone line isn’t damaged.
  2. Verify that youre calling the correct number, including any required access numbers (such as 9), and that the number isnt busy.
  3. Make sure call waiting is disabled on your telephone line when you connect to the Internet, so that incoming calls dont disconnect the Internet connection.
  4. Most dial-up modems only work with analog phone lines. Verify that you have analog phone lines installed, or, if you have digital phone lines installed, verify that your computer has a digital modem.

  To check USB network adapters

  If the cable that connects an external modem to your computer is a USB cable, you must perform some additional checks. A USB cable has different connectors on each end. One end is flat and rectangular, and the other end has a square connector with angles on two of the corners. To check a USB connection, follow these steps:

  1. If the modem is attached to the computer by using a USB hub, try to bypass the USB hub by plugging the cable from the modem directly into one of the USB ports on your computer.
  2. If the modem is plugged into one of the ports on the front of a desktop computer, try plugging the USB cable into one of the ports on the back of the computer instead. Some computers dont provide sufficient power to the front USB ports. This can create problems with the connection to the modem.

  If you’re having trouble determining the correct way to connect a cable, check the documentation that came with the modem, the network adapter, or the computer. If you made any adjustments to the cable connections, test for an Internet connection before going on to the next step. To test for an Internet connection, open your browser and try to access a website that you know exists (for example, http://www.microsoft.com).

  Check the indicator lights on your modem

  Check the indicator lights on your modem or Internet connection device (this can be either a modem, a modem and a wireless router, or a combined router-modem device). Most of these devices have an indicator light that is labeled "Broadband link," "Internet," "Online," or something similar that indicates a connection to the Internet. If youre unsure, refer to the documentation that came with the device.

  Reset the modem

  In some instances, the IP settings or network configuration that you receive from your Internet service provider (ISP) might be incorrect or need updating. Sometimes, the connection between the modem and the ISP might experience problems. To update the settings on the modem or the router, reset (restart) the modem. This creates a fresh connection to the ISP. Use one of the following methods to reset the modem, following the steps for your modem type.

  To reset an external modem

  1. Disconnect the cable that connects your computer or router to the modem. This can be either a USB cable or an Ethernet cable.
  2. Turn off the modem using the power switch on the front or back of the modem. If the modem doesnt have a power switch, disconnect the power cord from the back of the modem, or unplug it from the wall.

     Note

     • Some modems have a backup battery that prevents the lights from going out. For this type of modem, press and quickly release the Reset button. If you don’t see a Reset button, remove the battery instead.
  3. Wait several minutes, and then turn on the modem and reconnect the cable from the computer or the router to the modem.
  4. Restart the computer.
  5. Test your connection to see whether you can access the Internet.

  To reset an internal modem

  • Restart the computer.

  Use Device Manager

  Use Device Manager to verify that your network adapter is working correctly:

  Note

  • You must be logged on as an administrator to perform these steps.

  Check the network adapter

  1. Click Start, right-click My Computer, and then click Properties.
  2. Click the Hardware tab, and then click Device Manager.
  3. Double-click Network Adapters, and then right-click your network adapter.
  4. Click Properties, and then, under Device status, check to see that the device is working properly.
  5. If the network adapter is disabled, click Enable Device to enable it.

     Note

     • If the network adapter isn’t working properly, you might need to download and install the latest driver for it. (If you received an installation disc with the network adapter or with your computer, the driver might also be on the disc.)
       If youre still having problems finding the latest driver for your hardware, go to the "To download and install a driver yourself" section on the Update drivers tab of this tutorial.

  For more information about managing devices with Device Manager in Windows XP, see How to manage devices in Windows XP .

  Make sure the correct network adapter is being used

  Some computers might have multiple network adapters. For example, if you bought a new desktop computer and during the purchase you upgraded to a different network adapter, you most likely have an onboard network adapter (a network adapter built onto your computers motherboard) as well as a secondary network adapter inserted into an available slot in the computer. You can verify this by looking for two network ports on the back of your computer. (Network ports look like large phone jacks.) Laptops normally have just one network port unless you’re using a USB network adapter.

  To set the default network adapter

  1. Click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections.
  2. If multiple network adapters are installed, the default adapter will have a check mark and be labeled "Default."
  3. If the correct network adapter is listed as disabled, right-click it, and then click Enable.
  4. If the wrong network adapter is listed as the default device, right-click the correct device, and then click Set Default.
  5. Close the networking window, and then test for a network connection.
     
     

     Use the network troubleshooter in Windows XP

     An automated troubleshooter is a tool that can find and automatically fix some problems with your computer. These troubleshooters arent designed to fix every problem, but theyre a useful tool to try because they can often save you time and effort.

     Follow these steps to run the network troubleshooter in Windows XP:

     1. Click Start, and then click Control Panel.
     2. In the right pane, click Network and Internet Connections.
     3. In the right pane, click Network Connections.
     4. Right-click Local Area Connection, and then click Repair.
        
        

        Update drivers in Windows XP

        A network adapter driver is software used by your computer to communicate with your wireless network adapter. Outdated, incompatible, or corrupted network adapter drivers can prevent network connections or cause intermittent disconnections.

        If you recently upgraded from one Windows operating system to another, its possible that the current network adapter driver was designed for the previous Windows operating system. If youve had recent power outages, viruses, or other computer problems, its possible that the driver has become corrupted. Downloading and installing the latest network adapter driver can resolve these types of problems.

        Here are three ways to find and install a driver:

        • Use Windows Update. You might need to set Windows Update to automatically download and install recommended updates. Installing any important, recommended, and optional updates can update system features and other software that might help to fix your network connection problems.
        • Install software from the device manufacturer. For example, if your computer or network adapter came with a disc, that disc might contain software that installs a driver for the network adapter.
        • Download and install the driver yourself. You can search for a driver on the manufacturers website. Try this if Windows Update cant find a driver for your network adapter and the adapter didnt come with software that installs a driver.

        For more information about updating your network adapter driver, follow the steps below. For information about network adapters that are compatible with Windows, go to the 

        Update router and adapter firmware

        Your router or network adapter might need a firmware upgrade, especially if youre only able to connect using WEP security or no security. Firmware is the software that is embedded in a hardware device and controls how the device interacts with the operating system.

        Download a firmware upgrade from the router or adapter manufacturer’s website and apply it, following the directions on the website or with the downloaded file.
        
        
     
     

P.S. Microsoft released critical updates on every second and fourth Tuesday of every month.

There are mainly three type of Windows updates provided from Microsoft, based upon their importance:

Important: Such updates are important for keeping your system safe and reliable, covering all your safety and privacy concerns.

Recommended: It is important to update installed software and drivers from time to time to achieve best performance out of your system. Recommended updates will be provided with important updates which generally download and install updates for the running programs.

Optional: These are the updates about new or trail Microsoft software which you may able to install manually.

On the darkest side, if you don’t install these updates daily or weekly (at least), your system may starts freezing, crashing or suddenly becomes inaccessible. In worst cases, user may not able to access the stored hard drive data and the only way out to recover data is by using inaccessible data recovery software.

However, there are some common problems related to Windows updates which may leave your system in unbootable state. Let us understand the problems with such updates along with subsequent troubleshooting steps to make your system working again.

---

System become inaccessible after installing updates
In some cases, after installing one or two updates and security patches from Microsoft, the system was not able to start successfully and give error messages like Blue screen of death, failed start loop, stuck at booting screen etc. You’ll need to double check and ensure that the problem is surfaced after the update installation took place and you haven’t done anything else that causes system inaccessibility.

Older version of Windows such as Windows 7, Vista and XP comes with an option to start system with previously loaded system files and drivers, known as “Last Known Good Configuration”. You can use this option by continuously tapping F8 just after starting your system which will takes you to the advanced system startup options. In case you’re using Windows 8, try reset or refresh option on your computer.

Windows 7 offers various other useful tools to fix unbootable computer like startup repair, system image recovery or system restore. You can apply any or all the option and check if you may able to get into Windows once again. Once you able to access your system, you may perhaps want to look for the culprit and uninstall it if it were still there:

Under ‘Control Panel’ option, click ‘Programs’ and then click on ‘View Installed updates’ option under ‘Programs and Features’ tab. Select the update that you want to remove and click on ‘Uninstall’ option to begin removing that particular update. If you want to remove any recently installed updates, check out their details like date and time, update name and related services or programs.

System give freezes after installing updates

After installing recently available updates, you couldn’t able to access program, play music or simply turn it off. System does nothing except to stay there forever.

                                       

These are the security updates released for keeping your files and folders safe and prevent viruses to steal confidential data. The problem surfaced when updates were not fully installed or stuck at mid of installation and therefore hamper performance of other important system files use to boot and perform read/write operation.

Once you are at mid of such tragic circumstances and puzzled could save you from this, run your system using clean boot mode. Clean boot is a special technique to start system with minimal set of drivers and programs so could you find the culprit driver or programs and later able to start your system.

USB Device not working after installing update

Microsoft sometime releases updates for your USB ports to ensure faster and reliable performance for various type of USB Devices. These update also helps your computer in easily reading the stored content and alarms if there is any suspicious files trying to interrupt performance of your computer.

                                                 

On the other hand, sometime these updates make your system unable to detect USB devices. Moreover, it’ll make your system to freeze or hang as soon as you connect the USB device on your system. There is a special case that I’ve found where Windows 8 computer stop reading any USB device after installing update: KB2756872. Follow the steps mentioned below to free yourself from such problems:

1. Restart your computer and switch to BIOS settings.
2. Go to Advanced mode > USB Configuration.
3. Find option ‘USB Legacy support’ and ‘USB3.0 Legacy support’ and make it disabled.
4. Press F10 to save changes and exit from the BIOS.
5. Again, restart your computer.
6. Go to control panel > windows update and locate the recently installed updates after which, this all started happening.
7. Remove that updates and restart computer back again.
8. Again, in BIOS settings mode, set both the options to enable back again which we had previously set to disabled: USB Legacy Support & USB3.0 Legacy Support.
9. Save and exit from the BIOS by pressing F10 and hitting enter.
