My wifi on router is already set up but my wifi is not shown in the Taskbar wifi menu. I opened Network and Sharing Center. Clicked 'Change adapter setting' and when it opened its completely empty nothing shows up.
Then i opened System Information from run typing 'msinfo32'. Under components-> problem devices I have a list of problems they are:
-3D video controller
-PCI simple communication controller
-SM bus controller
That's all. I mean how do I solve them. The Error code is same for all of them: "the drivers for this device are not installed".
Where can I find those drivers from the Internet. My Pc is running Windows 7 ultimate sp2 64bit
