Hey Guys
I Have A Galaxy S6 Edge Plus And I Updated To Lasted Version Of Android ( Marshmallow )
The Problem Is I Have An Active WIFI Connection But Apps Can't Detect It !!!
For Example When I Open Facebook Messenger It Says "No Internet Connection" But Actually I Have Connection ... What Is The Fix For This Issue ? Thnx For Answer ...

Look in 'More Networks' and see if there is anything there about WiFi being visible?

Also, in previous versions of Android, there is a setting for the WiFi to keep scanning for a better channel... it has to be turned off....

I have never seen Marshmallow, so just shooting in the dark.

just have to ask.... are you doubly sure, that an internet connection to the outside world exists on your WiFi router?

I have seen that issue happen, more than once. The WiFi is there, but no outside world.

I Will Downgrade My Phone From Marshmallow To Lolipop And See If Works !!

Can you connect to anything over mobile data? It could be your wifi set up. Can you browse web with another device over your wifi router?
