Hello Flood
Thank you for contact to me.
Yesterday I uninstalled the karpersky internet security app
and I installed again. Today I go back to the Starbucks with the app Secure Connection and I don't know if it's help but it's working, I got internet.
Another difference it's that I go back with the web tracking unable.
I will still checking because it's a problems that I notice many times, until now only and Starbucks and only with my Mac, my iPhone always get internet.
Thank you for you help.
