Question about stream quality

Problem:

Hey folks,

I finally got the video stream with ffplay working with my GoPro Hero 2018. I am still getting lots of error reports but the video is kinda stable.

It just looks totally horrible, like 144p quality.

I tried upping the Stream Bitrate but that doesnt change the quality, just feels like the stream is more unstable.

Is there anything I can do about the quality?

Details:

ffplay -fflags nobuffer -f:v mpegts -probesize 16192 udp://10.5.5.9:8554
Cam is connected via Wifi PCI Card

Any help is much appreciated ! <3

Here is the cmd log when I use 1 Mbps:
