Connected, no internet access

I followed the steps you told me, and it's still the same.
My TV is still under warranty; I don't know if that would make a difference... ????

Thank you first of all for the time you’re taking to help me.
I did as you instructed.
I replaced the IP: 192.168.1.128 with 192.168.24.128 (the number by 24 because it was indeed that). Everything else was as you indicated. I turned everything off and on again, but still the same, the status of my WiFi is "connected, no internet access."
For your information, when I turned my TV back on, the IP address went back to the original one, which is 192.....1.128.
I’ve had it for a year and my WiFi works with my phone, my computer, it's just the TV that doesn’t work anymore. I'm with Bouygues.

Good evening.

For your first request, no, I am not using a hotspot; I've never done that anyway.
Then, what do you mean by 'web browser on the homepage of my bbox'? If you’re talking about the Home button on the standard bbox remote, there is no web browser, and I also don't see it in the 'settings' - 'wifi' section. In 'settings', I can only check the configuration of TV channels but nothing regarding the internet.
If you mean the internet search bar on my TCL TV, nothing happens because I have no connection.
As for my PC, it detects my WiFi well, and I am connected. The keys on my keyboard are not functioning properly, so I can't perform your operation with the AZERTY keyboard, sorry.
I will contact the manufacturer TCL directly because this is starting to annoy me.
Thank you anyway for the time you took.

I reassure you, I wouldn't have thought of that myself. Suddenly I got a message on the TV asking me to re-enter my Gmail password and then everything worked again, it resynchronized.
