Hi, 

I just bought a new TV KD43XH8096 with built-in Chromecast and airplay support. I have a wifi router supporting 2.4GHz and 5GHz wifi bands. My TV is connected to the 5GHz band. Unfortunately, if my phone is connected to the same wifi band as my TV none of the supported cast services (Chromecast or airplay) is available, but as soon my phone is connected to 2.4GHz wifi band the cast services becomes available even if the tv is still connected to the 5GHz band.

Is anyone here experience the same issue? 

Regards, 

Martin
