@Saint 

 

Thanks for the information provided. 

 

When the Deco M4 stops working and became red, please connect your computer to the cable modem directly to verify whether you can access internet. 

 

In the meantime, please click here to get the IP address and gateway obtained by your PC. 

 

If it works well, please connect the PC back to the main Deco via ethernet cable and open Deco app to clone MAC address. 

Note: Open Deco app, go to more-advanced-MAC clone, enable it and choose " Use Client MAC Address" and select the computer. 

 

Besides, you can swap the locations of the Deco units or switch the slave Deco to the main Deco to give it a shot.

@Kevin_Z

 

Can I connect to the M4 from a desktop browser vs. a device app?

If so, how?

 

F

rom a browser, how do I take steps needed to correct this disconnect?

 

I installed for my bro-in-law in another state.  so I have the app but he only has a browser.
