Problem connection to wi-fi internet

Question

Hello,

I installed and started my smart tv led 55 "model h6203. The TV correctly detects the wi-fi networks in the house but, by selecting one of these (which in particular comes from a range extender) and entering the password, you get the error screen where it is said that it is impossible to establish a connection.

Going in the control panel of the router however, the TV is detected among the devices present.

What must be done to solve the problem?

Thanks for the assistance.

Answer 1

In the end I found the solution.
Update the range extender firmware.
Simple as obvious, no DNS problem then.
I hope this helps.
