Hello,

I use the V3-572 with the WLAN /BT Atheros AR5BWB222 Chipset. I already installed the newest drivers from the Acer HP but still:

I cannot connect to my 5GHz Network. 2.4GHz works, 5GHz just states : Connection not possible. Since I have 3 other devices connectet to my Lancom-AP via 5GHz, I know the Acer V3 is to blame.

What to do? I use WPA2 / AES encryption @ 5GHz and I bet the Atheros chipset can´t handle that. @2,4GHz I use mixed mode WPA1/2 TKIP/AES, which the atheros can handle. 

But I refuse to believe that in 2014 a chipset is unable to handle WPA2/AES @5GHz.... Smiley Mad

 

PS: I even tried the "unofficial" drivers v. 10.0.0.287, but the problem remains.
