So, I decided to upgrade to win 10 and I did but I was stuck with a network problem. So I decided to switch back to win 7 but now the same thing is happening.

My network stays unidentified and I can't seems to fix it with a troubleshooting.
When I do the troubleshooting the result says that my local area connection doest have a valid in configuration. I really don't know what to do, everything worked before I made the upgrade to win 10 and switch back to 7.

Thank for the help.
