Correction to the above solution. After further review. The issue was completely with McAfee Update. This is a solution that  resolved my issue. Please make sure you have your McAfee subscription information handy or your McAfee registration information: User Name and Password. First you will have to uninstall McAfee completely either using suggested link or Uninstall Program from Windows us.mcafee.com/.../MCPR2.exe If you will get an issue with the removal process try to do it from safe mode. To enter safe mode. Turn off your computer. Then turn computer back on and right away press several times F8 to get to the Advanced Boot Screen from which you can chose Safe mode with Network Support Second you will have to restart computer and you should get internet connection after that Install download and install Java from www.java.com Next Use this link to log into McAfee website and re download McAfee and install it again. home.mcafee.com/.../login.aspx There is a new installation file on McAfee website that resolves issue with the network connectivity loss. Hope this was helpful to all of you.
Hello! So yesterday my Dell XPS 15 L702X laptop was working just fine and then this morning I open it up and I have no internet connectivity, whatsoever, not even when I plug the ethernet cable directly in. -I uninstalled the automatic updates that took place last night, no change. -I updated the drivers. -I flushed the DNS cache. -I made an "Admin" user, logged on, still nothing. -I cycled the modem. -When I run a ping test it says "No response: default gateway, DHCP" server.  I know the internet is working because I'm writing to you on another laptop which is connected just fine. I'm running a full scan on McAfee but as of yet there are no results. I tried to connect to other wireless accounts with no success.
