Hi there,
I run 2 ipq806x routers (Netgear R7800 & Zyxel NBG6817), which are connected to each other via ethernet cable. However, that cable is running outside our house (weather can damage it / someone can cut it) and I would like to have an automatic failover, when the cable connection fails.
About 2 years ago, I ran a wireless WDS between both routers, which worked remarkably fine, which I honestly didn't expect. No connection losses over the course of a few weeks, performance was great, I could stream and even game. So there is definitely no concern in that regard.
I want to set it up in a way, that the WDS / wireless connection always stays established, but all the traffic gets routed over ethernet cable. Once the cable connection fails, I want the device to transparently and seamlessly route over WiFi. Both routers run OpenWRT 19.07.4.
Afaik, the technical term for it is failover / teaming / bonding and I've heard it in context with two identical LAN / WAN ports. But I couldn't find anything like I want to do: bond (failover mode) LAN and WiFi.
It's very likely I'm searching with the wrong technical terms, but I couldn't find a way to accomplish it with OpenWRT. Hope someone can give me a few hints about this.
Thank you for your time!
Cheers,
Tolga
