I have a UE55RU7400U and I cannot connect it to my 5Ghz WiFi, I read that everyone have this issue, is there any kind of fix or what?
asking for info on amazon, manufacturer answer: we suggest to connect to 2.4Ghz cause the internal module is certified for that frequency
I was extremely disappointed to find out that the TV doesn't support 5Ghz, though it supports WiFi 802.11/ac. Is it locked in software level, or it is a hardware limit?
This is an old post but hope my story will help.
Samsung TV appears not compatible with 5Ghz if your Wifi Channel is higher than 36. I've been having similar problem. I have unifi AP so I was able to change my channel to 36 (tried 38 and 40 with no luck). 36 channel is the only one my Samsung TV can connect to. Hope this help.
Well, after deeper investigation RU7400 is one of Samsung's TV not supporting 5GHz network. This is discribed in the manual. In my case I have another series that is compatible.
