Hi @Kushal Sharma, great that you could post a picture of your TV as well! Does manual selection also not work? I see that you split the Wifi network into two separate networks for the 2.4 and 5 ghz variants, could you try to connect the TV to the 2.4 ghz variant? Is it a possibility to connect your TV with an internet cable to the modem? This always give the best internet connection on your TV and the best viewing experience.

I'm curious to hear more about your situation, this is definitely a solvable issue!
