While you didn’t name names of what app you were using for streaming, I just got into a similar situation with my dorm and what I found worked was using wired ALVR for my streaming. Not wireless, but good, long right-angled USB-C cables don’t cost a fortune. https://github.com/alvr-org/ALVR/wiki/ALVR-wired-setup-(ALVR-over-USB)
Hadn’t heard of pikvm before. Will keep that in mind, thanks!
