Wireless unstable

Hello everybody!

I've configured my wireless connection on Arch Linux using "newlan" and, after follow all steps, i sucessfully got access to the network.

But, once connected, the internet becomes really unstable: i mean, sometimes nothing works, and sometimes everything works well.

I imagined that could be a weak signal, but the signal is strenght (50/70), and always works well on Windows 7.

Someone have any idea?

Below are some informations about the system:
