I have frequent disconnections from internet using wifi. It happens only when I'm on my home network and it doesn't happens on other devices that are connected to my router. So it seems specific to this computer with this network. Here some info about my setup.
- Laptop: Lenovo X230
- wireless card : Centrino advance N-6205
- Ubuntu 12.04 64bits
- Kernel: 3.5.0-23-generic
- Network encryption: WPA
When it happens, the network manager applet shows that I'm connected but it's impossible to open an internet page. I have to reconnect to the network to have internet back.
Thanks for helping, much appreciate.
