FireTV 4k YouTube buffering in 4k

I bought a FireTV 4k a while ago and wanted to watch YouTube-Videos in 4k. My TV is capable of displaying 4k and my connection speed is fine as well, but everytime I try to watch something in 4k it just keeps buffering. Other devices in my network display 4k-YouTube without any problems and other services like Netflix or Prime Video work in 4k. I also tried using Smart YouTube TV (smartyoutubetv.github.io) and SmartTubeNext (github.com/yuliskov/SmartTubeNext) with same results.

Does someone have similar problems?

Have you done a speed test on your firestick to see exactly what kind of speed you're getting....

I'm using the ethernet adapter and the speed is always at around 60mbps. It should be enough to display stuff in 4k as the recommended speed is at around 20mbps (see: https://support.google.com/youtube/answer/78358)

OK so I’m guessing you’re using the Amazon brand ethernet adapter... Ok so if you are paying for Internet speeds over 100mpbs then you are not going to want to you the Amazon brand adapter because it will Max out at 100mpbs.... now I got all my 4K fire sticks hooked up by ethernet cable I pay for 300mpbs and with the set up that I have I’m getting around 230mpbs... The Amazon brand Internet out there could be your problem and you wanna make sure the cable that you are using is capable of pushing the speed that you are paying for.. I use this set up with a IPTV service and I get no buffering whatsoever and I never have any problems..... is The set up that I have...

But do I need a better ethernet adapter for 4k YouTube? Shouldn't 60mbps be more than enough?

How much Internet speed do you pay for each month... The thing is you can always order that stuff and if it doesn’t work out for you just return it back to Amazon....

Noob question. Why would you need a 4 pack of the OTG's? Isn't one all you need? Full disclosure, I have the stock FireTV 4K, no add-ons.

Not if you have more then one fire stick I have 3 4k fire sticks and I hope all three of my fire sticks up to my router.... you can buy just one but you’re going to pay about $6 just for one so..

Also make sure your device has plenty of storage on board because cause if the storage is low that will cause some problems... so any apps that is running in the background you’re going to want to make sure to Force stop and then clear Cache...

Make sure to reboot you FireTV from the System menu. I've had this issue on a FireStick and that wound up fixing it. Clear your YouTube app cache too

Have you tried on a 5Ghz WiFi signal rather than the ethernet adapter? Even if the signal strength is not great, it will help rule out some possibilities.

When you try 5Ghz just run a speed test to make sure you are getting at least 60Mbps like with the adapter

Also, you have tried many different 4k videos? I have had issues myself where certain videos will just not load.
