Comment 30 for bug 79626

I have the same problem. If i start my system with ethernet cable disconnect, the kernel dont recognize my connection, but qhen i start system with cable connected it works well until i desconnect the cable, when i do it the ubuntu doesnt recognize the link anymore. So i reload NIC's module. But my speed lan is correctly detected (100Mb/s) and i prefer reload the module and the networking services. Is it a kernel problem? I was using Edgy without problems, this problems appears when i upgrade my system.
