Model: Deco M5  
Hardware Version:
Firmware Version: 1.5.7 Build 20210819 Rel. 43499

So I tried just about everything in the book when hooking up these deco units. I've factory reset I don't know how many times, and tried switching main units but whenever I setup the units I get to configure the WiFi and then the light goes red. However, when I hook it up to my old router thats connected to the modem it works fine and I get a green light... But when its connected directly to the modem I get a red light.. I've updated it to the recent firmware.

Hi, May I know who is your internet service provider?

Maybe you could try to do a MAC clone on the Deco:

How to Configure MAC Clone on Deco if Deco fails to connect to the internet?

And the following link will also be helpful:

@TylerM 

How about the MAC clone on the Deco?

(Or you could find the WAN MAC address from the web UI of the old router and manually copy it into the Deco.)

Would it work?

And please also have a look at the private message.
