Just like my Galaxy 4 before it, my Galaxy Note 4 will show I am on WiFi before I even log in. In some instance, such as with my home WiFi, my secure WiFi will automatically log me in, but for the more public WiFi's I use at the multiple facilities I go to, my first sentence applies. When I do need to log in, often it takes several minutes to get the log-in page to really be on WiFi. It is usually an important WiFi site to be on, to communicate with my office, and engage in some activity for work. This false indication that I am on WiFi is one of the things I really hate about my Samsung dumb-phone. I'm sure there is nothing I can do about it. I have disabled smart network switch to no avail.
