Dhcp lease not updating dns
I rarely recommend system restore as a solution because most of the time system restore just mask the real problem and give a temporary solution.
But considering the fact that you tried all the above steps and none fixed the problem, try doing a system restore to a date when the internet was working fine in your computer.
Then I tried the diagnostic tool link that popped up in the webpage, which showed me DNS Server Not Responding Error.
If none of this worked, contact your ISP to get further help in fixing the problem.
I was just about to post an article on a different topic, but then I noticed that for some reasons, some websites were not opening up.
There were no error messages and the web page comes with an option to click on diagnostic tools to find the cause.
