I have no internet on my tablet Samsung Tab A 2016 because it says "Connected, no internet" I have reset network settings but nothing… I have on all other devices, regardless of whether Android, iOS, pc, laptop…
do you have other solutions, I don't want to completely reset the tablet…
Can you reach the main fritzbox page with the tablet in the web browser?
do you have a lock or filter active? Parental controls active?
I can reach the website of the router with the IP address and a lock / child protection should not be there, because the father tried to solve it himself.
bdw i write as a friend of the owner of the tablet, so don't be surprised if you get confused when i swap people…
Ok, i would then look at wlan settings from the tablet, whether everything is set to auto DHCP.
