I hope this will help your concern.
My computer has always had internet problems but nothing that doesn't fix's it self of i fix it with no issue. Recently my computer says its connected to the internet but when i try any websites(you tube, tumblr, wired etc), it says i'm not connected. I have opened cmd and used the ping command to see if anything comes up but nothing does. There is no response from the websites. Help would be much appreciated.
