Yesterday was the first time I used my new tablet. ALL FINE. Even on my balcony (I'm at the beach), had a great wifi signal/use. Today, can't connect to it. I have been through every single troubleshooting step and none of them fixed it. NOW...also today, I updated the system (said it was due/available). Wondering if there's a bug in the update. I need help, please. What do I need to do, outside of every single troubleshooting step that I have ALREADY done, numerous times??
