I need your help, I face some network problems, ...during install and after install ubuntu wasn't enable to connect to the network. It keep saying that the network cable is unplugged or without connection.
I did an update throught wireless USB connection but it dosen't resolve the problem, I follow some post sugestion about downgrade network-manager and so on, but nothing change.
Here are some facts and details.
* In my router, the clients's DHCP table shows the machine host name and it assigned an IP... (that means that my router sees the PC in a right way?), although doing ping return nothing.
* Parted-Magic running on the same machine connects to internet without any problem, also I did try to compare some settings and information and everything looks the same (as far as I understand).
