Windows 7: Windows 7 unidentified network no internet access

Ok one week ago i brought a new PC with windows 7 so im kinda new to this OS.
Well today i got a Mcafee notification that some program i hadnt heard of before wanted to get internet acces so i pressed block.
After that i lost internet connection so i waited and after 15 mins i restarted my modem and router , now my whole network is gone.
And now when i press the option connect and i enter the username and password of my router i get an error message and now i got unidentified network no internet access.

Already tryed turning off mcafee and firewall.
