I have a Asus eee PC 1001PX running ubuntu 12.04. Everything works well but the wifi is unstable. When I boot the wifi works fine, but after about 5-10 min it gets slow, disconnects etc and the computer starts to run slowly. The it is ok after reboot, for about 5-10 min.
Any ideas? I have tried everything I have found with google but nothing works. I have tried a few different wifi routers and it is always the same.
