Wireless Joint

take a look at the project https://github.com/TalalMash/SmoothWAN
its build base on OpenWRT and using Speedify bonding more than 2 wans together,
i tested on ras pi 4 and r4s nano pi, speed is over 500Mbps.

I want to build this as well.
How stable is this setup for whole-house:daily use comparing other routers with the same modem?

Thanks
