DTEK 50 cannot log on to public wifi

Almost every time I try to log onto public wifi at a caf� or diner, the a message pops up that says my session has expired and I am re-directed to their home page. The most frustrating part is that every once in a while, I don't know how, or why, I am able to log on. Can anyone help?

Try forgetting those networks and then letting them re-register on your device. Also, keep in mind public WiFi is generally crap and overloaded running off of routers that have likely never been rebooted lol.
