You configure an exception in the firewall on the Windows option " Service Access Network ". To do this , "Start " -> " Control Panel " - > " Windows Firewall "- > "Edit Settings " - > Exceptions tab - > check " Service Access Network "- > " Apply " -> " Ok ". Then I disconnected and reconnected to my network after a small delay of 5- 10s. I had internet in wifi. Conclusion do not forget to check the configuration of your firewall, it could block any programs used to connect to the net.

This means that this is not the website is blocked but the address resolution is not being done correctly. The DNS replies that he does not know so the browser does not have an IP address to contact the Web server. Take a look in the file C: \ WINDOWS \ system32 \ drivers \ etc \ hosts . After a series of lines beginning with. You should have only the following line.
127.0.0.1 localhost.

Public access to the Internet is a protected freedom , but sadly endangered . During the discussion of web laws, it was a time proposed by the Ministry of Culture establish a " white gate " to curb public access wireless and restrict them to a predetermined list of sites " clean. " Such a system could be applied in parks or town halls but also in libraries and other similar services providing wireless access to their users. Faced with the threat of attack on freedom of access to information, IABD had already responded through a declaration.
