I am using xfinity internet and for the last few days I have been unable to connect to most websites while using my Windows 10 based laptops and desktops. My Mac is able to connect to any/all websites and I have no problem connecting on my iPhone and iPad. I have tried using several different browsers and using both wireless and wired connections. I have tried using the "flushdns" command and essentially every other fix I could find. Aside from google owned websites and Wikipedia, I cannot seem to connect to any other sites. When I attempt to connect to other websites, I am met with the "This site can't be reached" message (ERR_CONNECTION_TIMED_OUT)...any help/suggestions would be greatly appreciated.
