I don't think it's the case. I've just descovered even stranger behaviour: If I'm donloading/uploading something or just listening internet radio everything if fine!!! Look carefully at http://vovan.homelinux.org/stats/traffic/traffic.html and then http://vovan.homelinux.org/stats/ping/ping.html. In between 8 and 10 I've been using bittorent and ping has been as low at it should be! Now I _REALLY_ don't have any idea what is it... :( Liste de diffusion modem ALCATEL SpeedTouch USB Pour se d�sinscrire : mailto:[EMAIL PROTECTED]
