3.I tried to reinstall Minecraft and deleting the ".minecraft" file, logging off and in mc restarting my modem trying many versions 

4.I tried turning off the firewall but nothing worked so please I need help I can't play the game like this 

I mean I don't enjoy it so please if someone can help me I will be so thankful
