Samsung smart TV connected to Uverse cable box & Samsung Smart TV can not connect to internet
I have a Samsung 65" smart TV connected to Uverse cable box. I can access TV channels & Netflix/Youtube/HBOMax apps provided by At&T Uverse. But when I try to access any Smart TV app like Netflix, AmazonPrime or even Internet app --> I get no network connection. Looks like my smart TV is only connected to internet via cable box. It can not access internet using wifi. NOTE: Wifi works on all my other devices like phone, laptops, etc.
Sincerely need help with this as looks like I have a Smart TV but can not use it.
