I'm new to Here & not very tech savvy to put it mildly. I have a samsung galaxy 10.1 tablet. Whenever I'm on the internet/websites, the following appears "couldn't establish a secure connection". It appears for every website and pops-up every few seconds. Another website referred me to the "type" of security on the tablet. It isWPA2 PSK which is supposed to be good security but I get the above popup EVERYTIME AND MORE THAN ONCE WHILE I'M ON A WEBSITE. What does this mean , ; why does it happen; &if it's a problem, how do I correct it.
