Hi guys I have exactly the same trouble. Freeze on wifi, no problem with cable. Before Vero 4k+ also no problem on wifi. So it has to be Vero V problem.
I wrote a while ago different ticket about wifi channel width when I use 40 against 80MHz it is better.
Now for a while I have strange but working workaround.
I had to turn on bandwidth limiter for Vero V on my Asus rt-ax57.
Without bandwith limiter I get around 150mbps (no freeze when I measuring) freeze when I playing big movies. I set up bandwith limiter to 100mbps and no freeze. Usually 100,90 mbps is enough for UHD.
