I guess my ISP uses some subpar hardware because the connection keeps dropping at peak hours. I want to implement a failover system without having to buy some expensive router which I would not be able to justify with my normal usage.
Wanted to know some other ways how people do it .
I have gigabit cable and fail-over to VDSL2.
I use a UDM-Pro with dual WAN configured. I previously used PfSense with load balancing and feel it did it better than the UDM-Pro, but there are other benefits to the UniFi ecosystem.
