Pi-hole has a habit of crashing in the middle of the day when family is working. Fixing it takes some time which is unacceptable to them. I am using an Asus router with Merlin firmware. Pi-hole is Version 5.0 so it has the groups feature, but if the pi crashes , the by-pass feature using groups is useless.

Path 1) run another Pi-hole on separate Pi for redundancy.



OR path 2: The fix I Was thinking was: have a separate wifi for my devices that uses pi-hole as DNS. I want to leave my primary router and its wifi untouched, so under normal circumstances people use pi-hole based wifi. In case pi crashes, quickly shift to the other wifi.

The 2nd Asus router works as a LAN to WAN bridge and has a different subnet / wifi SSIDs / Pi-holes etc, so acts like a complete separate network.

From what I have read, in Bridge mode (called media bridge) 2nd Asus will not broadcast wifi. I don't want to run a LAN cable between the 2 routers (impractical) and if I keep them close i have noticed 2 wifi routers running close by interfere a lot.



I am not too bothered about the speed, I have read repeater/bride mode splits BW by 50%, I am ok with that.



If anyone has such a scenario running, please help.

If your issue is the DNS server crashing on your Pi, just add in a secondary DNS server as a backup in case the primary goes down. This way you don't have to mess with having to set up a completely different layer 2 network which contains a specific DNS server you're looking to do as a backup.
