WiFi connected but no internet

[Ninko]

Hi,
I recently bought a Tab S6 for my partner but am having a problem with the WiFi.
It will be connected fine then randomly out of the blue the internet will stop working and the WiFi symbol will have an exclamation mark next to it.
The only way to fix it is to disconnect and reconnect WiFi - untill it happens again.
All my other devices connect to the same WiFi network fine without any problems.
Any help please?

Thanks

Hello! I've got a problem with the wifi on my Samsung Galaxy A10s and it’s that when I’m far from the router sometimes the internet is gone even it won't load any  page properly and the phone still connect to the wifi (but on another device, it still works fine) I just have to turn the wifi off and on again for solving this, but I wanna know if this is a hardware problem or is the simple answer: “I’m too far from the router “?

I had the same problem, but then I realised that I installed a game for which I had to change date and then I never reverted back to original time. I changed the date to real time, issue resolved , thanks

Thank you!  This fixed the problem on my Samsung Galaxy Tab A 10.1.

Dud you try changing time to Auto as recommended above?  I did and it worked for me.

This worked for me as well on my Samsung Galaxy Tab A, which is about 10 years old now and had no real issues other than this, which is now fixed thanks to the suggestion on this forum.
