What should I do if the crack card is not used under Win 7 or is not normal?

Q: My friend's laptop has been upgraded to Windows 7. I found that the card that I used to use often doesn't seem to be normal under Win 7. I can't use it. If it is used under XP, it's good. I don't know. What should I do?

A: Windows 7 below use card emperor /card king, such as "crack card" may need to install a separate driver, but some cards are also used under the system built-in driver is also normal. In general, if the wireless network card is not working properly, it is recommended to install a proprietary driver. For example, if the card is used by the RTL8187 chip, you can find the driver of the 8187 chip wireless network card under Windows 7 on the Internet. After you find it, you can update the driver in the device manager. If the wireless network card is still not working properly, you may need to restart the computer, and the wireless network card will be used normally.
