Yes I did drop to NETGEAR 2.5.2.4 first to avoid the soft brick.@Gregger96 :
You speak of NETGEAR versions 2.7.2.104 and 2.7.3.22. You also mentioned you "reverted to stock". For Voxel's 9.2.5.2.X builds you have to downgrade to NETGEAR 2.5.2.4 first; then, you can drop Voxel 9.2.5.2.X on. Just validating that you have done this.
I am using 9.2.5.2.14 and I have video calls that last several hours without interruption. I have 2 satellites, one is wired to the router, the other is wireless backhaul to the router.
