Hi @Kenny029, I set the reboot schedule so that nbn modem and the px50 (using app's reboot schedule) reboot at different times( half hour apart). All px50 are connected by Ethernet cable. when losing connection, it simply say no internet connection in app. network layout is: modem -- main deco -- switch -- two other px50. The issue is the reboot schedule in deco app. I have tested that if I set up the reboot schedule in the deco app, after rebooting, all deco lose internet connection, only after I manually reboot my nbn box, the system will be back to normal. I also tested several times: if I just reboot the nbn box, no the deco, it works fine (internet connection restores) after the nbn box reboot, no action is needed; if I manually reboot all deco (I click "reboot deco" in deco app, choosing all deco), it still works fine after the reboot is done. I believe there is a bug when using "reboot schedule" in deco app.

I have this on two ISP, one uses dynamic ip, another one uses the credentials. I have the old nbn box for HFC.
