this is my story:
I left my laptop at home connected to the router and with teamviewer on. Remotely I was controlling it about 2 hours, at a specific moment the connection has disapeared. When I came back, the laptop was on and still connected to the router but no internet connection.
- The router is fine, if I connect another device it works.
- I still can see other wifi networks and try to connect to them.
- I was not installing anything new software on it while controlling it remotely.
- Nobody touched it.
- It was not a power failure, everything was like I left it.
- Tried with a life cd, same situation
- Ubuntu 12.10 on Acer Aspire 7730
