Orbi RBR20 does not have wifi internet while connected to a switch

[casadlocho]

After so many factory resets i finally figured out why i keep losing my wifi internet.

My home network looks like this:

COX > MODEM (CM1100) Port 1 > ORBI RBR20 INTERNET PORT > ORBI ETHERNET PORT > SWITCH 

Anything that's hardwired to the switch have internet connection but any device connected to the wifi does not.

Can someone explain to me why?

ardware Version	RBR20
Firmware Version	V2.5.1.16
GUI Language Version	V1.0.0.375
Operation Mode	Router

Not to confuse anyone.

COX > MODEM (CM1100) Port 1 > ORBI RBR20 INTERNET PORT

ORBI ETHERNET PORT > SWITCH

As soon as i remove the connection to the switch and connect all device to wifi alone then it starts working again.

People have reports issues with some green switches or managed switches. 

What switch do you have? 

[casadlocho]

I have the netgear prosafe GS108.

My goal is that all house hold mobile devices to be connected through wifi.

And for my desktop and laptop to be wired via switch.

Faulty switch or cabling? Try a different switch. CAT6 LAN cable is recommended.

Switch and Cables are all a week old.

Cables are CAT 6.

This is an entirely new set up.

I am always connected to wifi. but since i started working from home i wanted to connect my work computer wired.

Also, if switch is connected directly to my modem. Every device connected to it gets internet connection.

If Modem is connected to Orbi all wifi devices gets internet connection.

The issue only happens when orbi is connected to a switch via the ethernet ports. It shuts off wifi internet but devices connected wired still gets internet. I hope i am explaining my self clear.

Has a factory reset an setup from scratch been performed since last FW update? 

Disable Daisy Chain on the RBR.

I would try a different brand switch to see if reset or daisy chain doesn't do anything. 

Is very odd behavior. Switch should not effect any wifi operations. I know my RBK50 is connected to many switches including the RBS which is ethernet connected as well.

I just tried replacing my ORBI with my linksys EA7500 router and it does not have any issue.

Right now i have my modem connected to linksys EA7500 , and a cable is connected to a switch via the routers ethernet port. All devices wired and connected via wifi have internet.

I strongly believe that something is wrong with my Orbi. But since i purchased it 2018 it is out of waranty.

I just hope i find away to solve this as i definitely do not want or need a new router.
