Q: Why my wireless network connection is disabled and can not be enabled?
To verify the wireless network connection status, please go to the Network Connection Window. For Windows XP, Click on Start. Click on Run. Enter "ncpa.cpl" and click OK. For Windows 7 or Windows Vista, go to "Search programs and files" box. Enter "ncpa.cpl" and hit the Enter key.
If you see the wireless network connection icon is disabled in the Network Connections Window, you may double click on it to enable the connection. Should it is still disabled an no way to be enabled, you may have a AntiVirus software (for example, Kaspersky, ZoneAlarm, Trend Micro Internet Security...etc) installed in your computer and it disabled the wireless connection.
You may completely remove the antivirus software from your computer and restart the computer. Check the wireless connection can be enabled. Then you can re-install the antivirus software.
If you prefer not to uninstall the antivirus software, you may check the properties of the Wireless Network Connection. You may find an extra service from your Antivirus software installed and usually it is a check box with something called NDIS Filter. Uncheck that box. Click on OK. Restart the computer. You may be able to enable the wireless network connection
