Is anyone using Orbi RBK 852 with comcast business gateway
Trying to determine the most stable way to add this router to my network and if it is possible to only turn off the wifi function of the comcast gateway and still use the ethernet ports as the router has too few but I do already have an unmanaged switch on my network. Is bridge mode acceptable for this I keep seeing there are ip conflict issues in bridge mode. Network has around 60 devices currently and low signal strength on the far side of the shop which is why i am adding the router and satalite. Hope this is in the correct topic and sorry there are multiple questions here firt time reaching out to a community but I am in dire need to resolve this issue as it is effecting my business.
Thank you in advance to anyone that can help.

Your kind of caught with a problem that'll either require an investment (another switch) or to run the netgear in access point mode.
Right now you're in a double nat.
A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions. But then you can't use the ethernet ports other than the 1 to connect the netgear to.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference. Problem with this route is the 2 devices are still in seperate subnets and devices on the seperate ones might not be able to see each other.
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

4. Put the comcast device in modem only, run the netgear in router mode, and add another switch.
Kind of up to you which route you use.
