I had installed Ubuntu 11.04 via Wubi in my Windows 7. I have a DSL conncetion in which I have to give a username and pwd given by my ISP in the edit connections. Recently I chose to upgrade to ubuntu 11.10 and then on ubuntu 12.04.
I am able to connect to my connection but I am not able to surf on my browser. But when I am able to connect and use the internet in my Windows 7. My connection loads the driver r8169.
I have Toshiba satellite L505-10X laptop. I had the same problem in Ubuntu 11.10 few months earlier but back then I chose to switch back to Ubuntu 11.04.
I was looking online for answers and i had read that it loads the r8169 driver instead of r8168 and that could be a problem. So I did try to solve the issue with those answers but it didn't work.
I am not an expert in ubuntu/linux so I don't know what the problem is. Please help if anyone ever faced the same problem and has solved it.
