I bought a set with 3 DECO M4 routers, configured the operator's router as Bridge and DECO as a router. With each power outage, the main DECO loses all configuration and I have to reconfigure it again, I have done this dozens of times. What is the problem with this type of router? This is very annoying, I gave up changing the name of the devices on the network, there are more than 30 devices and always changing all names, doing parental control, changing DNS ... THIS IS VERY CHAT. It is the worst router I have had to date, I have been in the IT field for over 20 years and I never got a router that bad, I want to know if this is NORMAL, is it really bad?
