How to make the internal wireless adapter be enabled on boot?

Today I installed windows 7 on my laptop. After installation of drivers and updates, I found the wireless adapter was not
enabled by default. Then I checked the device manager to make sure that my driver worked. I didn't find any question marks
or exclamation marks in device manager. And then I tried a restart of my computer. But the adapter still stayed disabled.
Then I tried pressing the combination of fn + f12, finally the adapter came to alive. And I could successfully connect to the
router and surf the Internet, but after another reboot, the adapter didn't show up automatically, instead I had to press that
combination of fn + f12 again. Before this installation, my computer usually worked automatically with wireless adapter
loaded on boot. So I wanna know how I could make the internal wireless adapter be enabled on boot without turn it on
manually.

Thanks.

It probably would help if you tell people the model of your laptop. Maybe some setting on the software that manages your wireless. Have you had a look at your user manual already?

Have a look inside the BIOS settings. I believe the button to get to the BIOS while the PC is booting up is F10 .

Hi, VistaKing. You are totally right. I set the BIOS to its default, everything turned out to be normal again. Thanks for anyone who is trying to help. Peace.
