Argh. Just purchased this Acer Aspire V3-571G-6407 with Windows 8 for Christmas, and the wireless network card fails several times per hour. To temporarily fix it, I have to go into Control Panel -> Network and Internet -> Network Connections, then select my WiFi connection and click 'Diagnose this Connection', which reset it. And then maybe it will work for another 20 minutes before failing again. VERY frustrating.
I saw on the Acer support site that they've been having problems with the Qualcomm Atheros AR5BWB222 network adaptor. I downloaded and installed the most recent driver today (Driver Version: 10.0.0.217). This seemed to speed-up my WiFi connection significantly, but did NOT resolve the intermittent WiFi network adaptor failures.
Can anybody help? I'd hate to return what is otherwise a solid laptop.

What do you mean by network card failure? Are you getting "Limited connection" and/or wifi dropouts?
If you scan through the forum you will see similar wifi problems for V3, V5, S7 even with the latest wifi drivers.

Hi. I have the same exact problem. I have an acer V3-571G and i have the latest version of the drive (10.0.0.217). I think I have found a solution. I went to device manager --> Network Adapters --> properties on the network wireless adapter --> power managment tab and deselected to turn off the adapter to save power option. Till now it doesn't seem to have any problems.

I'm having a similar problem with this adapter on the Aspire V2-551-8469. However, mine is not intermittent. It stopped working all together as if it were switched off. I tried your suggestion on the power management, but to no avail. This is very frustrating as I've only had the laptop 6 weeks. If anyone has any other ideas, please pass them on. Thanks in advance.

Nice one indeed Acer. On my Acer M5-851PTG I have the same issue. I am currently running v 10.0.0.200. I will define telly download and see what's happening after the upgrade to 10.0.0.217 v3 though I doubt that..

As originally supposed the update didn't solve the issue of intermittent WiFi failure. Moreover - the failure is frequently now... I think I'll call for service a.s.a.p. For an almost 1000EUR PC this is unacceptable.
