how to install firmware for wifi when lan is not working

[Md Ashickur Rahman Noor]

Do you have windows? If you have then goto
System-->Administration-->Hardware Drivers. You will see your hardware
listed to install driver. Click the active button. Then it will give you a
error message. There you will find the download link. Just download the file
and install.
