Pi 3b non plus version
Hyperhdr 20.0.0.0
both are on 2.4ghz

It is connected for about 2-7s and then disconected 2-7s which makes the led just turn of and on. Also the preview is pretty laggy

This sounds like a common wifi issue.
Can you please try to use Hyperion/HyperHDR as a first attempt directly on the TV? If the preview is working fine here, it might be related to your local network. In this case you can also try to use an ethernet cable
