Hey @Anthony_Yeung, I’ve moved your reply into it’s own post so that we can properly assist you.
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Additionally, as a first step, can you please try changing the DNS to see if this will allow you to stream higher quality?
We have seen users have a better experience in the past if they change their Router’s DNS servers from the ISP provided ones to Cloudflare DNS, Quad9 or Google DNS. Can you please give this a try and let me know if it helps?
Thanks!
