One day when you least expect it, you or an end-user will discover no Internet connection on Internet Explorer. This may not appear to be a major issue since there are numerous free Internet browsers available to utilize but if the alternate browsers are not yet installed or at least downloaded, how will you utilize them? Most times, the installers for the browsers are trimmed down and must have an Internet connection to gain all the files to have a functional installation.
One of the thongs to check right away is the current time on the clock. If the time is incorrect, it can have sites with SSL Certificates form loading thus appearing that there is a serious network connection when in fact it is not.
When the time change has no effect or was already correct, the next thing to do is to try and access websites using private browsing to rule out issues with cookies.
Reset the Browser
When al else fails, just reset the browser and move on. This way, you can reach out toother user experiencing issues or get tasks done if the system was your own.
