Okay, here's my story
Got mine laptop back from the service center on Tuesday. Everything seemed to be ok except for the wireless - it couldn't find any wireless networks, although there were pretty many of them around. I noticed that the wireless button behaved quite strangerly - blinking with not so bright light as it used to be. Okay, I tryed to disabe and enable wireless by pressing the button and windows just froze. This happened every time I tryed to diactivate and then reactivate the adapter.
All right, I then spent an entire day trying to figure out what was causing the problem. My assuption was - drivers. Reinstalled everything I might possibly think of - no results. Okay, Restored everything back to factory defaults - no results. Okay, installed WinXP x64 edition - the same problem. That's when I finally thought that the problem was related to hardware. Wireless network card, maybe?
Okay, took wireless card from my second Acer Aspire (the card is identical to the one installed in Ferrary), no result. The card working in Aspire refused to work with Ferrari. Went back to the service center. They told that it could be deffective motherboard and they would try to replace it, this time for free.. Okay, but I again need to wait another week or so to get the laptop back.
So; any of you experiencing problems with wireless after the repair should now know what to do
I'll keep this updated when I hopefully get Ferrari back working like it should have always been..
