Wifi dropping with AR9285 Atheros card on Fedora 16

I have a Acer Aspire One netbook, with a AR9285 Atheros wireless card. I've installed fedora 16 recently, and everything else works out of the box, but the wifi is very, very unstable (which is really annoying). I basically using two types of connection (college network and company network): One is WEP 40/128 bits, and the other is WPA & WPA2 Enterprise, with PEAP authentication. On both networks, I can connect, but it keeps dropping randomly. Sometimes it stays stable for an hour, give or take a few minutes, but then it drops again. I tried downgrading to kernel 3.1.0-7, and it got a little better, but still very unstable and annoying.

lspci:
01:00.0 Ethernet controller: Atheros Communications AR8132 Fast Ethernet (rev c0)
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

iwconfig:
wlan0
IEEE 802.11bgn ESSID:"KS Inovacao"
Mode:Managed Frequency:2.437 GHz Access Point: 00:18:E7:5E:3B:3A
Bit Rate=54 Mb/s Tx-Power=14 dBm
Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=70/70 Signal level=-33 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:40 Missed beacon:0
(as you can see, it's not the power management thing)
