I'm use Debian wheezy on a Acer Aspire One AO725. It has the following kernels:

The command lscpi | grep Network:

02:00:0 Network controller: Atheros Comunications Inc. AR9485 Wireless Network Adapter (rev 01)

The computer must have the following settings (IP Static):

allow-hotplug wlan0
iface wlan0 inet static

Some times the computer works fine with WIFI, in other times not works WIFI and Ethernet (with the same settings). What happened?

How can I fix my problem?

Does both the WIFI and Ethernet work and then not work or is it just the WIFI? –  slm May 13 '13 at 15:47
What happens is that I have configured the wifi stops working and configure the ethernet (turn off the wifi), but now it does not work. –  Cristian Chaparro A. May 13 '13 at 17:37
