[Acer Aspire S3-391] Wifi problem on Windows 8

[Acer Aspire S3-391] Wifi problem on Windows 8




I bought my ultrabook(Acer Aspire S3-391) 1 month ago.

When I bought it, Windows 8 was already installed.


But there is wifi problem(Atheros AR5BMD222).

Just very rarely connected.



I did below things to fix this problem.


Upgrade BIOS

Upgrade wireless driver( v3 / / after unintall and delete previous version

(I tried 3 versions)


Upgrade router's Firmware

Change Power option(Maximum Performance)

Not allow the computer to turn off the device to save power

netsh winsock reset catalog (reset winsock entries) / netsh int ip reset reset.log hit (reset TCP/IP stack)



I tried to find information regard to this problem to fix. And I followed someone's suggestion.


But it doesn't work. In my opinion, the problem is caused by windows 8.


I have the other lap-top(ASUS, windows 7), and it works very well.


My mobiles, ASUS lap-top, IPAD. Everyhing works very well.


I am waiting for your suggestion.


Thanks very much in advance.

I had all those problems and I reverted the driver to .075. This mostly solved the wifi drop out problem.


A couple of days ago, the new Atheros 10..0.0.218 appeared in the Acer LIVE updater, which I then installed; I have had no wifi dropouts so far. Not sure where you got your from? Anyway, just a suggestion, activate your Live Updater, and try the .218, maybe that will fix it.


Good luck.

Re: [Acer Aspire S3-391] Wifi problem on Windows 7

It's been 7 days since we bought this ultrabook and we couldn't figure out how to fix the wifi issues. It connects and disconnects. We tried to install the latest wifi drivert as well, but that makes it even worse. We couldn't connect. Please someone help...
