|So, if the blue light is on then the mainboard knows that your wireless card is there and it is capable of switching it on and off. |
Now, so I am assuming that you know for a fact that your wireless router is working correctly and is broadcasting. An you have already check this with a different computer or device like a smart phone.
It sounds like now that you have installed some other wireless connection client that has disabled the windows one. So we have to re-enable it.
Here is how you can enable/disable this feature:
1. Go to Start and right click Computer. Select and click Manage.
2. Computer Management window will appear. Under Services and Applications, select Services.
(Another way to reach this is: Start -> Control Panel -> Administrative Tools -> Services
3. Scroll down and select WLAN AutoConfig.
4. Double-click the service and its properties window will appear. If the startup type is not set to automatic, click on the dropdown arrow and change it to Automatic. Click Start to start the service if it’s not started. Click OK at last.
