I am really sorry that we still seem to be having the issues. As per the update, I believe that the computers do not have any issues and the connections are working fine on the computers and it is only the mobiles and tablets that has issues with authentication and internet access. If you could please let us know what is exactly is happening on the mobile devices. Please also update the case with your preferred callback number and time do let us know if we can call you back for further troubleshooting.
