My three rb750 routers with version 7.1, always restart automatically.why,please?

thanks

Are you using cake or codel on simple queue with interface as target?

Why you install unstable firmware on 3 devices, without wait if is stable on at least one?

Use netinstall for install back 6.47.10

no,the rb750 have been reset configure,set pppoe only,but always restart automatically.

The network use SSTP+OSPF+EOIP now. Becoase SSTP is speed low, I will use wireguard+ospf+EOIP .I found that wireguard cannot be multicast

Unable to work properly. Has been rolled back to version 6.47.10
