CBR750 Downstream LED always blink white light

My Orbi CBR750 is getting internet connection from my ISP router via LAN connection and its always blink its downstream LED white light all days. I really want to turn it off but in the settings, there isn't such an option for that.

Can someone please help me?

Blinking usually means its scanning for a downstream channel. 

do you have a screen snip of the cable connections page? That shows the link status

You have no locked upstream or downstream channels. 

Is your connection working? I've never seen one without locked/downstream upstream working. Smiley Happy

Did you get it activated by your ISP?

check your coax for kinks, damage, old/bad/cheap connectors. 

Remove any splitters, amplifiers, or attenuators from the line.

Ensure you're connected to the coax where it enters the home to ensure you have a direct connection.

Yes, its working and its getting internet connection from another router. I only use CBR750 as wifi router so i don't use coax connection.

That's why you're having issues with the lights blinking. 

Its searching for a modem connection when its not setup as a modem. 

That model doesn't have an option to disable the modem portion. 

 

Why are you using a different modem? The CBR750 has a docsis 3.1 modem and is one of the more advanced modems out there.

Sadly, you'll probably have to put up with it unless you can return it/exchange it for the unit without the built in modem. (RBK750)

A little black electrical tape might help cover the light Smiley Happy
