my laptop sunddenly say there is no wirless card install, but sometime ok sometime not?
when its not ok, when i try to turn the wireless on, the light for the wireless not on?
the wireless card is internal, and tried updated already and uninstall and reinstall!

seem hardware issue, contact customer server for service.

That's right.  If you have re-installed the correct driver, still have problems occasionally, I would say it is hardware related too.

Is it an on-board network card or PCI?
