I have a Dell Inspiron n4030 notebook and I am connecting in a wired network in my office using the Atheros Network AR8152, running Ubuntu 10.10 Maverick.
After 20 minutes aproximately, the connections stops to respond, but the status is still "connected". I can't ping the machines in my network or reach internet. The cable and the IP I am using are the same I was using in my old workstation and works fine.
If I try to send an e-mail through gmail with attached file, the connection allways reaches this scenario above.
It works fine with Windows 7.
