Why does my Galaxy Tab S 10.5 not download with WiFi sometimes?

[AC Question]

Recently, my Galaxy Tab S 10.5 has intermittently stopped letting me download over WiFi. WiFi Analyzer shows that I'm connected and that the connection is strong. But the tablet won't actually bring up anything from the Web. Occasionally, though, it will work, then stop again. Any suggestions??

Welcome to Android Central! Does this happen on any wi-fi network, or only a certain one? Do you get an error message, or does the download just not happen? When this happens, are you able to browse the web normally?

Is this only happening with websites using your browser, or also with other apps?

It has happened on more than one network. I don't get an error message, instead nothing happens. I can't browse the web or download anything. It is happening both with apps and with several browsers that I've tried. As I said in my post, Wifi Analyzer shows that I have a strong signal and I'm connected.

Does it happen in Safe Mode as well? https://support.t-mobile.com/docs/DOC-28736
