Troubleshooting Wi Fi Connectivity issues

INTRODUCTION :

Troubleshooting for wireless networking with Windows XP requires gathering information, checking the drivers, verifying compatible hardware, and configuring wireless settings.

Troubleshooting Wi Fi connectivity issues is almost same on operating system's that came later after XP as like Windows XP.However , accessing the same on different operating system's could be different.So, if you aren't able to figure out please ask for help in the comment's below.

Information to gather

Before you begin troubleshooting, make sure that you have answered the following questions:

What is the symptom? If it is an error message, note the full error message.
What wireless card is used? Note the manufacturer and the model number.
What is the driver version for the card? Look in Device Manager or click Configure in the Properties dialog box of the wireless connection.
What access point is in use? Note the manufacturer and the model number.
Are the wireless settings configured by using Windows or by using a third-party program? If a third-party program is used, what is the program and its version number?
Is the Wireless Zero Configuration service running? To determine if the Wireless Zero Configuration service is running, follow these steps:
1. Click Start, and then click Run.
2. In the Open box, type cmd, and then click OK.
3. Type sc query wzcsvc, and then press ENTER.
4. If the Windows Zero Configuration service is running, the words "STATE : # RUNNING" will appear.
If the problem is in the user interface, collect a screen shot of the issue, if you can. To collect a screen shot, press ALT+PRINT SCRN.

Basic Troubleshooting :

To troubleshoot wireless network connections in Windows XP, follow these steps:

Check the Windows Catalog at http://www.windowsmarketplace.com to determine if there is a Windows XP-compatible driver that is available for your wireless adapter.
- If there is a compatible driver, install the updated driver before you perform any additional troubleshooting procedures.
- If there is not a compatible driver, you may be able to use the network adapter, but its configuration and functionality may be very limited.
Determine if the driver that you are using recognizes the Windows XP Wireless Zero Configuration service. To do this, follow these steps:
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 Wireless Network Connection, and then click Properties.
5. View the available options:
  - If you do not see the Wireless Network Connection icon in the Network Connections folder, or if you cannot view the properties, there is a problem with the driver for the wireless network adapter. To troubleshoot this problem, see the Driver installation issues section.
  - If you can view the properties for the Wireless Network Connection icon, but you do not see a Wireless Networks tab, see the Drivers that do not support the Wireless Zero Configuration service section to continue troubleshooting.
  - If you can view the properties, and you can see and use the Wireless Networks tab, see the Drivers that support the Wireless Zero Configuration service section to continue troubleshooting.
  - If the Authentication tab is missing in the Wireless Network Connection properties, make sure that the Wireless Zero Configuration service is running.

Driver installation issues

If you do not see the Wireless Network Connection icon in the Network Connections folder, or if you cannot view the properties for the Wireless Network Connection icon, there may be a problem with the driver installation. To troubleshoot this issue, verify that you have the latest available driver from the device manufacturer, and then follow these steps to determine the cause of the issue:

Click Start, right-click My Computer, and then click Manage.
Click Device Manager, and then double-click Other Devices and look for the wireless network adapter. If you find the adapter in the Other Devices folder, no driver has been installed. To resolve this issue, obtain and install a driver from the device manufacturer.
If you do not locate the adapter in the Other Devices folder, look in the Network Adapters folder.
When you locate the wireless network adapter, note the manufacturer's name and the model of the adapter.
Right-click the icon for the wireless network adapter, and then click Properties.
Verify that "The device is working properly" message is displayed under Device status.
If the wireless network adapter is not in the Network Connections folder, there is either a problem with the device or the driver may not be installed. In this case, you will see an error under Device status.

You can search the Microsoft Knowledge Base for information about the error code to use in troubleshooting this problem. To search the Knowledge Base, visit the following Microsoft Web site:
http://support.microsoft.com/gp/gsssearchhelp

Drivers that do not support the Wireless Zero Configuration service

If you can view the properties of the Wireless Network Connection icon, but you do not see the Wireless Networks tab, the network adapter driver does not fully support the Wireless Zero Configuration service, or the Wireless Zero Configuration Service is not started. You may be able to configure Windows XP to use the connection, but the configuration options may vary depending on the network adapter and the driver that are in use. To resolve this issue, try to create a working connection by following these steps.

Note If you cannot create a working connection, contact the device manufacturer for advice about how to configure the adapter for Windows XP.

Verify that the Wireless Zero Configuration service is running. To do this, follow these steps:
1. Click Start, and then click Run.
2. In the Open box, type cmd, and then click OK.
3. Type sc query wzcsvc, and then press ENTER.
4. If the Windows Zero Configuration service is running, the words "STATE : # RUNNING" will appear.
Click Start, click Control Panel, and then click Network Connections.
Right-click Wireless Network Connection, and then click Properties.
On the General tab, click Configure.
Click the Advanced tab, and then configure your wireless network by using the available configuration options. The available options and option names may vary depending on the driver manufacturer. The following list describes the basic configuration options under Property:
- Service Set Identifier (SSID): This setting must match the configuration of your wireless access point or router. If you do not have an access point, this value will be the same on all the computers that are in your wireless network.
- Wireless Equivalent Protocol (WEP) or Encryption
  
  Warning The following step may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this option, but we are providing this information so that you can choose to implement this option at your own discretion. Use this step at your own risk.
  
  For testing purposes, turn off WEP on both the access point and in these properties.
  
  Note WEP is designed to help protect your computer from attack by malicious users or by malicious software such as viruses that use unsolicited incoming network traffic to attack your computer. If you decide to implement this step, take any appropriate additional steps to help protect your system. Turn WEP back on as soon as you have finished troubleshooting your network connections.
- Mode or Network Type: If you have an access point, set this option to Infrastructure. If you do not have an access point, and if you are connecting your computer to another computer, set this option to Ad-Hoc.
- Data Rate: Set this option to Auto or to 11 Mbps.
- Power Save: For troubleshooting, set Power Save to Off or to Disabled. After the connection works correctly, you can change this setting.
After you configure these options, click OK to save the changes that you made.
Test to see if your connection works. If a red X is displayed over the connection icon in the Network Connections folder, or if you cannot connect, continue troubleshooting.
Click Start, right-click My Computer, and then click Manage.
In Computer Management, double-click Services and Applications, and then click Services.
Right-click Wireless Zero Configuration, and then click Properties.
In the Startup type box, click to select Disabled, and then click OK.
Close Computer Management, and then restart the computer.

With this configuration, you can connect to the wireless network if the other network configuration is correct. If the Wireless Network Connection icon is displayed in the notification area as a working connection, the wireless connection will work. To resolve any remaining issues, use standard TCP/IP network troubleshooting techniques.

For additional information about TCP/IP troubleshooting, click the following article number to view the article in the Microsoft Knowledge Base:

Drivers that support the Wireless Zero Configuration service

If the Wireless Networks tab in the properties of the Wireless Network Connection is available, the driver recognizes the Windows XP Zero Configuration support for wireless networks. To configure Windows XP for your wireless network, follow these steps:

Click Start, click Control Panel, and then click Network Connections.
Right-click Wireless Network Connection, and then click View Available Wireless Networks.
Click the network that you want to connect to, and then click Connect. Follow the steps in the wizard to configure the network. If your network is not listed, verify that the access point is powered on and configured, move the computer and the access point closer together, and then test again.
If your network is still not listed as an available network, click Change advanced settings to open the wireless network connection properties.
On the Wireless Networks tab, click Add to manually configure settings for a network.

When you save these settings, you can use them automatically when the network is available. Available settings include the following:
- Network name (SSID): The Network name (SSID) setting typically matches the configuration of your wireless access point or router. If you do not have an access point, this value must be the same on all the computers that are in your wireless network.
- Network Authentication and Data encryption: Options here include Open, Shared, WPA, and WPA-PSK. If you are using WPA, no additional configuration is required. If you are using WPA-PSK, an 8- to 63-character password is required.
  If you are using Open or Shared authentication, you can either enter a key, or indicate that a key is provided automatically. In home network configurations that use WEP, the key is typically entered manually. You may also choose no security by setting Data encryption to Disabled. However, we do not recommend that you do this except as a troubleshooting step.
  
  Warning This step may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this option, but we are providing this information so that you can choose to implement this option at your own discretion. Use this option at your own risk.
  
  If you have to disable security for troubleshooting, turn off WEP on both the computer and the access point. Turn off WEP on both the access point and in these properties for testing purposes.
  
  Note WEP is designed to help protect your computer from attack by malicious users or by malicious software such as viruses that use unsolicited incoming network traffic to attack your computer. If you decide to implement this step, take any appropriate additional steps to help to protect your system. Turn WEP back on as soon as you have finished troubleshooting your network connections.
- Key index (advanced): This is an optional setting that specifies which of four positions the key is stored in: 0, 1, 2, or 3.
- The key is provided for me automatically: This check box option indicates that the key is provided from the network or stored on the network adapter. You must only enable this key when the network administrator or the network adapter documentation specifies that you enable it.
- This is a computer-to-computer (ad-hoc) network; wireless access points are not used: This check box option is used to specify a computer-to-computer network that does not include an access point. If this option is unavailable, click Advanced on the Wireless Networks tab. In the Advanced dialog box, you can click to selectAccess point (infrastructure mode) networks only to enable an ad-hoc network.
After you save this configuration, repeat this process on the other computers on your network.
After you configure the settings for the other computers, you will see the network name SSID in the Preferred networkslist. If you see a blue circle, the network has been located; if you see a red X, there may be a problem with the radio signal between stations on the network, or the configuration may be incorrect. Confirm that the settings on your network are correct, and move the computer closer to either the access point or the router, or to the other computer on the wireless network.

After you complete the configuration steps, the wireless connection will be correctly configured.

If you experience issues when you try to connect to the network, double-click the Wireless Network Connection icon in the Network Connections folder to view the Connection Status window. In the Connection Status window, there is a signal strength meter that you can use to verify the strength of the signal between the computers.

Strong signal

If you still have trouble connecting, but the signal strength is good, a different network configuration issue may be preventing communications. To resolve this issue, use standard TCP/IP troubleshooting techniques.

Weak signal

If you still have trouble connecting and the signal strength is not good, or no signal is received, try the steps in the Drivers that do not support the Wireless Zero Configuration service section. If the method that is described in that section does not resolve the issue, contact the manufacturer to determine if the wireless network adapters and the access point are working correctly.

Driver missing or not installed

Code 28 Error Message :

The Code 28 error is one of several Device Manager error codes. The Code 28 error will almost always display exactly like this:

"The drivers for this device are not installed. (Code 28)"

Details on Device Manager error codes like Code 28 are available in the Device Status area in the device's properties: How To View a Device's Status in Device Manager.

Important: Device Manager error codes are exclusive to Device Manager. If you see the Code 28 error elsewhere in Windows, chances are it's asystem error code which you should not troubleshoot as a Device Manager issue.

Cause of the Code 28 Error

A Code 28 error is caused by a missing driver for that particular piece of hardware. There are any number of reasons that a driver might not be installed for a device but your troubleshooting of the problem will be the same no matter the root cause.

Error Code 28 Troubleshooting

Restart your computer if you haven't done so already.

There is always the slim chance that the Code 28 error you're seeing in Device Manager was caused by a fluke with Device Manager or in your BIOS. If that's the case, a reboot might fix the Code 28.
Did you install a device or make a change in Device Manager just before you noticed the Code 28? If so, it's very possible that the change you made caused the Code 28 error.

Undo the change, restart your PC, and then check again for the Code 28 error.

Depending on the changes you made, some solutions might include:
- Remove or reconfigure the newly installed device.
- Roll back the driver to the version prior to your update.
- Use System Restore to undo recent Device Manager changes.
Update the drivers for the device. Installing the latest manufacturer supplied drivers for a device with the Code 28 error is the most likely solution to the problem.

Important: Make sure you install the drivers for the correct operating system. For example, if you're using Windows 7 32-bit, install the drivers designed for that specific version of Windows. Many Code 28 errors are caused by attempting to install the wrong drivers for a device.
Install the latest Windows service pack. Microsoft regularly releases service packs and other patches for their operating systems, one of which may contain a fix for the cause of the Code 28 error.

Note: I do know that certain service packs for Windows Vista and Windows 2000 have contained specific fixes for some instances of the Code 28 error in Device Manager.
Replace the hardware. As a last resort, you may need to replace the hardware that has the Code 28 error.

It's also possible that the device is not compatible with this version of Windows. You can check the Windows HCL to be sure.

Note: If you still think there is still a software/operating system component to this Code 28 error, you could try a repair install of Windows. If that doesn't work, try a clean install of Windows. I don't recommend doing either of those more drastic options before you try replacing the hardware, but you may have to if you're out of other options.

Please let me know if you've fixed a Code 28 error using a method that I don't have above. I'd like to keep this page as updated as possible.

Applies To

The Code 28 error could apply to any hardware device in Device Manager but most Code 28 errors seem to affect USB devices and sound cards.

Any of Microsoft's operating systems could experience a Code 28 Device Manager error including Windows 8, Windows 7, Windows Vista, Windows XP.

Running Programs in Compatability Mode

Most programs written for Windows XP also work in later version of Windows, but some older programs might run poorly or not at all. If a program written for an earlier version of Windows doesn't run correctly, use the Program Compatibility Wizard to change the compatibility settings for the program. To change settings for a program manually, use the individual program's Compatibility tab.

If changing the settings does not fix the problem, go to the program manufacturer's website to see if there is an update for the program.

Warning

Do not use the Program Compatibility Wizard on older antivirus programs, disk utilities, or other system programs because it might cause data loss or create a security risk.

Run the Program Compatibility Wizard

Open the Program Compatibility Wizard by clicking the Start button , clicking Control Panel, clicking Programs, and then clicking Use an older program with this version of Windows.
Follow the instructions in the wizard.

If you cannot install a program, insert the installation disc for the program and, using the wizard, browse to the program's setup file, usually called Setup.exe, Install.exe, or something similar. The wizard is not designed to work on programs that have an .msi file name extension.

To change compatibility settings manually for a program, right-click the icon for the program, click Properties, and then click the Compatibility tab.

Setting		Description
Compatibility mode		Runs the program using settings from a previous version ofWindows. Try this setting if you know the program is designed for (or worked in) a specific previous version ofWindows.
